chartplotter Buyer’s Guide

Remote controls and mobile devices

Remote controls and portable readouts are available in some form on almost every plotter system. These are typically simple, powerful devices – fully waterproof and ruggedized – such as the Raymarine S100 remote pilot control. Now, manufacturers have designed apps so that tablets and mobile devices can provide full-featured route-planning and second-screen services. New plotters have WiFi connectivity built in – older devices need WiFi units that are sold separately.

But even more powerful is the ability to interact with online services offering live weather data, navigation warnings and other water users in real time from the plotter screen (or its mobile device extension). Owning a Furuno TZtouchfor example, now links you in with the online community surrounding the ActiveCaptain website providing anything from fuel prices locally to marina availability and urgent marine navigation updates. Garmin’s Quatix watch features a plethora of sailing-specific navigation features, but it is also capable of remotely controlling a Garmin autopilot – an interesting safety consideration in the event of a man overboard, if cruising single-handed. And Navico’s GoFree system, which serves B&G, Simrad and Lowrance devices, has been spun off into a company all of its own. For the latest in network-enabled boating instrumentation, see: Digital Yacht launches iKommunicate gateway box.

Garmin Quatix GPS watch can be used as a remote control for your autopilot.

Almost all of the current ranges of plotters from B&G, Garmin, Simrad and Raymarine offer sailing specific software features including laylines, tacking angles, heading and course-over-ground lines and true wind data fields. B&G’s powerful SailSteer and Sailing Time screens on the Zeusand cheaper Vulcan range take all of the guesswork out of VMG and upwind ETA calculations. And Garmin offers racing technology in its high-end 7400 series and top-of-the-range 8000 series, with more generic features throughout the rest of its range.

But these manufacturers also offer instrument-sized screens that can be customised to show raw data as well as offering advanced calculations and processing power. In the case of Raymarine, the i40, i50, i60 and i70 ranges of multifunction instruments and its range of wireless instruments (formerly known as Tacktick) offer great sailing-specific info – especially for racers. Garmin offers the GMI 20 display, Simrad offers the IS40 and B&G offers its Triton range.

BG Triton instrument range – an able extension of the multifunction display.

The other really useful added extra is the forward-looking sonar that is available from B&G and Simrad, and Panoptix from Garmin. Although this would be of benefit to any boater, yachts typically have a much deeper draught than a powerboat of the same size and move more slowly, enabling them to take evasive action based on the instrument’s readout.

Sonar wars

When specifying your sonar weaponry, check carefully that you’ve budgeted for the transducers. The 3D systems, such as Garmin’s Panoptix and Navico’s StructureScan 3D require a bewildering array of supporting kit, some parts of which cost over £1,000. Installation may also be a challenge if retrofitting. Some transducers need precise positioning angles on the boat’s deadrise to operate efficiently. Transom and in-hull options are also available.

All the major players provide sounder modules to go with their top-of-the-range screens. These screens and modules are very pricey, but bear in mind that as sonar technology continues to improve, the next generation modules will only work with today’s newest systems.

Lower down the scale, the market divides between dedicated fishfinder-plotters and “fishfinder versions” of plotters that include processing software built in. The Furuno GP1870F, for example, is a dedicated fishing version of the GP1870. Raymarine’s A Series and C Series are also available with dual-channel sonar processing built in.

Dedicated plotter-fishfinders include Garmin’s EchoMap range, Lowrance Hook and Elite Ti and Raymarine’s Dragonfly range. Check carefully to ensure the built-in software meets your fishing needs, because apart from occasional software updates, there may be little leeway to expand the screen’s capabilities as technology progresses. Also, these units vary in terms of the amount of NMEA connectivity and other “standard” chartplotter facilities they can accommodate.

Beware dedicated fishfinders that have no chartplotting capability at all. Of course, there’s nothing wrong with simple GPS-enabled fishfinders, or the Humminbird Onix series and Helix series, which offer plotters as optional extras, but don’t assume the plotter is built in. It’s easy to get carried away with all the sonar capabilities of the Garmin Striker, say, and forget the navigation side altogether.

Handheld

Many people own a handheld GPS unit which they bring with them hiking, bicycling, or driving. A marine GPS unit looks very much like these, except that it includes marine charts. Handheld models are as portable as they come, and they tend to be less expensive than the other types as well. They have fewer features however and the small size of the screen may sometimes be inconvenient.

Fixed mount

These are the largest marine GPS units and come with a mount. They do tend to be the most expensive, especially if you purchase the touch screen variety. If you are willing to pay even more, you can get a unit which you can network with your radar and sonar.

Chartplotter

Remember, always keep some paper charts handy in case of a power failure.

Fish-finder

If you are a fisherman, you definitely will want to look for a marine GPS unit which includes a fish-finder. A fish-finder uses sonar technology to measure the depth of the water and also to track the positions and movements of fish. This allows you to lower nets and lures to just the right depth to catch unwary underwater denizens.

Adequate screen size and resolution

It is important to try and purchase a GPS with a reasonably large screen and high resolution. Screens which measure at least 5” diagonally are best; others squeeze the view too much when using zoom or split screen. The higher the resolution the better—you will be able to see more detail.

Less expensive marine GPS devices feature an output of around 100-300 watts. This is sufficient if you are fishing at a depth of 200’ or less, but for deep sea fishing, you need more power.

Transducers

The transducer in your fish-finder focuses the beam. The more focused that beam is, the deeper it can penetrate—even at the same power level. If you double the diameter of the transducer crystal, it will have the same effect as quadrupling the power.

Electronic compass

While your basic marine GPS can track your position, it cannot tell which direction you are facing. That means it can only tell you if you are going the right way when you are moving—but it cannot point you in the right direction when you are still. For that, you need an electronic compass.

Additional charts and maps

You can also buy additional maps to go with your marine GPS device. Obviously the more built-in maps and charts your device includes, the better—but you may wish to shop for detailed maps of areas you frequent which include enhanced contours and labeling. This can streamline navigation.

Garmin’s 78sc marine chartplotter. Its display is easy to read at any time of the day, plus the depth alarm feature will keep you from running aground.

Awesome display. Some displays are hard to read in direct sunlight, but the Garmin GPSMAP 78sc’s screen is easy to read no matter what time of day (or night) it is.

Extended battery life. You can get 30 hours of continuous use or more out of this device, which is more than enough for a full day of sailing.

Fast performance. The processor is powerful enough to allow you to switch screens with ease.

Garmin technology. Like most Garmin products, the Garmin GPSMAP 78sc features excellent support and an easy-to-use navigational interface.

Floats on water. If you drop this device into the ocean, no problem. Just scoop it up and keep on sailing.

OTW Staff

In 2016, the lines between “marine” electronics and “personal” electronics continue to blur as fishfinders, radars, and multifunction displays take technology and design cues from the smartphones and touch screens we use in our everyday lives. The electronics on our boats are becoming more connected to our personal devices and to the cloud, and the result is better performance, greater usability, and an incredible wealth of information at your fingertips every time you hit the water. If you haven’t upgraded your fishfinder in a few years, you’ll be blown away by what’s available and by the incredible technology that can be purchased today for a fraction of what it used to cost to consumers. Take advantage and make the most of your limited time on the water by making it safer and more productive.

LOWRANCE TOTALSCAN TRANSDUCER

Receive the benefits of greater fish-target separation and less interference for a more clutter-free display with CHIRP sonar, plus photo-like images of fish-holding structure on both sides of your boat with StructureScan HD, along with the same photo-like images directly beneath your boat with DownScan Imaging—all in one transducer. The Lowrance TotalScan Transducer reduces the number of separate transducers required to take full advantage of all the latest fishfinding features of Lowrance systems. The Lowrance TotalScan transducer offers additional versatility with multiple mounting options.

ICOM M25

The M2handheld VHF radio is a sleek, stylish unit with big features and long battery life. Although it’s compact, it has a large LCD display and easy-to-operate buttons. A built-in lithium-ion battery will typically provide up to 1hours of operation and is charged through a micro-USB connector. If you happen to drop the fully-buoyant M2overboard, the Float’n Flash feature lets you know where it is with a flashing red LED light.

SIMRAD G0XSE

The Simrad GOXSE is a powerful, full-featured standalone marine chartplotter/fishfinder packed into a compact, easy-to-use display. The GOXSE features a super-bright multi-touch display, internal Hz GPS receiver, StructureScan HD and CHIRP sonar, autopilot integration/control, engine data monitoring, full audio entertainment integration with SonicHub 2, integrated wireless connectivity and the powerful, new Simrad TripIntel trip computer.

STANDARD HORIZON HX380

The HX380 from Standard Horizon is a commercial-grade submersible handheld VHF packaged with a 1,600 mAh lithium-ion battery that provides up to 1hours of use on a charge. It is factory programmed with all USA VHF marine channels and features a dedicated button for quick access to emergency channel 1and hailing channel A preset key allows quick access of up to commonly used channels. A 110-volt AC and a 12-volt DC charger are standard.

SIMRAD SONICHUB 2

SonicHubfrom Simrad upgrades the original SonicHub audio entertainment system to allow complete control from Simrad’s NSS evoand NSO evoMFDs and glass-helm systems. Features include Bluetooth audio streaming, a video output for playing files from a USB drive, dual USB ports for connecting and charging multiple devices, a 50W-by-amplifier and integrated support for Pandora internet radio via mobile device.

FURUNO NAVNET TZTOUCH12F

With a 12-inch multifunction display, an internal GPS antenna as well as an internal fishfinder, the NavNet TZtouchcombines striking design with simple operation for a sonar/chartplotter combo that helps you stay on the fish.

Garmin Echo 551DV Fish Finder

The dual beam transducer uses the 77/200 kHz frequency and 50/200 kHz dual frequency. Additionally it has DownVu capabilities that allow to nearly photographically view the structure and fish underneath the boat.

The 5-inch high resolution display offers zoom, horizontal and vertical viewing, and a split screen mode for viewing the broadband sonar and down image side by side.

Other features include waterproofing, audio alarm for when to be ready to cast and catch. For easy installation the device comes with quick-release tilt-swivel and transom mount, and low profile trolling motor transducer.

Garmin Echo 100

For those looking for a black and white best fish finder under 200, we would recommend considering the Garmin Echo 100 model.

It features innovative target tracking technology that gives data on fish, structure and bottom. It features single beam sonar with the frequency of 200 kHz, which allows monitoring the underwater to the maximum depth of 600 ft. So it’s a more suitable device for fishing in freshwater lakes.  The sonar power of the model is 100 watts (RMS).

This unit is also small, so it’s also the perfect choice for a small craft. The installation of the Echo 100 is a snap with the included quick release tilt mount.

Humminbird 140C Fishin’ Buddy

Humminbird 140C Fishin’ Buddy is one of the top rated fish finders among the portable type. So you can use it on your boat, on the leased boat, on the dock or for fishing from anywhere else. To use the device you won’t need to do any rigging or wiring. Instead it uses extendable transducer tube housing with the length suitable for most small and mid-sized boats.

The wattage for the device is 1000 watts. Purchasing it, you have several options. You can either choose a black and white or color screen option. One more selection is of either dual or single beam sonar.

Humminbird ICE-35

For ice fishing enthusiasts one of the recommended and top rated fish finders is the Humminbird ICE-3model. One of the most liked features on this device is the zoom flexibility. It allows you to zoom in not just to the bottom, but also zooming in for more details in any part you choose of the water column. The three color fiber optic display gives you a clear view of the readings. The extreme temperature LCD technology reports the lake bottom and automatically sets the flasher. Other features include dual frequency, maximum 200 depth capability and 800 watts peak-to-peak.

Transducer

Transducer is the main part of the fish locator. It sends the sound waves and shows what is underneath the surface of the water. The sonar signal that the transducer sends into the water, bounces off of the objects that are underwater and then gets picked up by the transducer. The signal is then translated into a picture.

When checking the transducer, the most important feature is the cone angle. For a bigger perspective of the verges underneath, choose a bigger degree on the cone. The wider beam gives more coverage of the under water and allows locating more fish within it. However, its drawback is the quick loss of strength. Due to this, it cannot penetrate the water as deep as the narrow cone. The narrow one can go really deep even in shallow waters and can also give information on the composition of the bottom.

To get the most of the both there’s the dual beam type of transducers. It’s also called dual frequency and which combines both features in one unit. Other types of transducers are more specialized. They include multiple beams (can be or more). These cover a larger area of the underwater and can even give a 3D image on the display. One more option is the side beam transducer. These units shoot their signals to the sides, which increases the search area for fish.

Frequency

When choosing the fish finder, you also need to choose the unit with the right frequency, which is also an important feature of the transducer. The frequency is directly related to angle of the cone. On most of the transducers you can find the following frequencies: 50, 83, 19and 200 kHz. A higher frequency will give you more detail on the screen. You can find models that offer dual, single and multiple frequencies.

Fish Finder and GPS in One Unit

If you are looking for an ultimate fishing tool, consider adding GPS to it. The Global Positioning System (GPS) with the help of satellites calculates your exact position.

A GPS is a must have for many fishers and having it in one unit with a fish detector is economical, space saving and convenient. Having the addition of a GPS gives you many benefits. It will give you the ability to mark hot fishing spots and easily return to them in the future, as you can mark the spot on the GPS and then track your way back to it later. These spots are called waypoints and on most units you will be able to mark hundreds or even thousands of them.

A GPS also gives you navigation through the waters. For this you will need to select a unit that comes with background maps and charts. One more benefit of the addition of the GPS is safety. Wherever you fish, you will have the confidence that at the end of the day the GPS will easily point you home. For example, you could be fishing throughout different locations during the day, or you could lose sight of land, or some severe weather could suddenly roll out. In such situations, a GPS will give you the exact direction to your home and will tell you how far it is.

How Does a Fish Finder Work

Understanding how a fish finder works will help you to understand how to use it. Fish finders work using sonar. It’s a technology that uses sound waves to display underwater objects. The fish finder produces the sound wave and with the transducer sends it through the water. Penetrating the water deeper, the sound wave starts to spread in the form of a cone (commonly called a beam). As the wave encounters objects within this beam, it sends the signal back to the transducer.

By calculating the amount of time between when the sound wave was sent and when it bounced back, it measures the distance and shows it on the screen. If the wave doesn’t encounter anything on its way, it reaches the bottom. If the bottom is soft and it’s just mud and weeds, the signal gets absorbed. A rock bottom will reflect a stronger signal back.

If actual screen size is not as important as advanced features, then the Humminbird 409460-688ci HD DI is a great choice. This internal GPS/Sonar combo fish finder puts the cost where users really want it, the features. It is an upgrade from the lesser Humminbird models and maximizes the fishing experience with GPS chartplotting, DualBeam PLUS sonar, memory storage capability, and a 25color digital display. When combined this all the best standard Down Imaging it is a superior device on in the fish finding market.

Garmin echo 500c

I have nothing but praises for this unique fish finding tool. Somehow Garmin has outdone the competition with a fish finder that has all the right features. The Garmin echo 500c Fishfinder is a slightly better item, than the one reviewed above. For users that have the extra money to spring for this upgrade, this is the better purchase. The 500c Fishfinder is the intuitive level fish finder, as it uses an uninterrupted sonar view. The product boasts about its priority software or Garmin Smooth Scaling technology. With this device handles depth changes without losing sight of any sonar histories. An additional feature allows users to rewind through their sonar histories. That is a sure way to not miss a stroke during any fishing adventure.

Humminbird 409470-600 698ci HD SI

As Humminbird products increase in price, so does the quality of their devices. The Humminbird 698ci HD presents an effective Side Imaging innovation at a value without extreme prices. It has a splendid 25color on a 5″ illuminated screen. The 698ci sparkles like a fish discoverer and chartplotter should. It uses very conventional 2D sonar includes Side Imaging and Down Imaging. This gives users the opportunity to see pictures at 100 feet deep. Wow that is really cool.

Humminbird 409140-859ci HD DI

Another Humminbird combo? Well it isn’t just bias. When the objective is to catch all the fish possible, the correct hardware is significant. Poles, reels, and watercraft can take an angler far. To ensure they know where the fish are gnawing, more fishermen are swinging to the Humminbird 409140-859ci HD DI Combo Color Fish Finder.

Humminbird 409150-899ci SI HD

I rank the Humminbird 409150-899ci SI HD Combo Color Fish Finder as superior. Except for the online media hype being unclear about what you are getting or how to redesign. This isn’t to say that this is a bad Humminbird model, but lets assess it fairly.

How does a fishfinder GPS work

In orbit around the earth in geosynchronous positions, numerous satellites are sending out radio signals that your GPS is picking up. By doing mathematical calculations, it figures the angle between the location of the receiver and multiple satellites that give you a fix. This them is converted into latitude and longitude and inside your GPS on the charts that are calibrated in longitude and latitude and icon symbols is displayed indicating where your boat is now.

When your boat is moving the calculations that indicated the direction and the amount of time of travel between point-to-points gives you your speed. Waypoints on the chart and line between them and your simply compare your icon against where the line is. The closer you follow the line between two waypoints the more accurate your navigation.

How to mount a fishfinder GPS

After opening the box, verify that all mounting hardware is there. Mount the transducer where the directions say. Run the wires to the unit. You have to drill holes. After doing so make sure you waterproof and seal all of them. Take particular care where the transducer cable enters the hull of your boat. The fish finder’s mount mounts where it is easily accessible and visible. This will depend on the type of boat you are using. Most anglers place the transducer on the transom. They place the display unit near where they sit while maneuvering the boat.

A depth sounder is a coarse device that you send out a pulse and measures the return to give a bottom sounding. A fishfinder has much more discrimination. It allows focus on smaller objects at varying depths. The controls, therefore, are more sophisticated. With units that have a multibeam capability. You can see a three-dimensional view of what is beneath your boat. This allows you to identify fish much better. It also gives precise depth positions.

How we tested them

We made up a temporary washboard to fit in the companionway of Polly, my Impala 28, and mounted our plotters and instruments into this.

One major advantage of NMEA 2000 is that it means all compatible instruments can talk to one another, regardless of manufacturer, so we connected our B&G, Raymarine and Garmin instruments to the same network. That meant they were getting the same wind, speed, depth and heading data and their functions and computations could therefore be easily compared.

Starting from just off Cowes, we placed a waypoint on each plotter miles upwind, at Pol Roger buoy just off Lee-on-Solent, hardened up and looked at each plotter’s presentation of laylines and upwind angles. We experimented with tidal offsets, true wind angles and real-time settings. As we approached the mark we could zoom in and compare each plotter’s predicted laylines.

Once round the mark, we looked at each plotter’s downwind settings, then set up a startline at Coronation buoy to try out each one’s start line features, if available.

B&G Vulcan 7

B&G introduced the concept of laylines to plotters, and their clear and simple display has changed little since. A major advantage of the B&G kit is the ability to ‘damp’ the instrument data, which makes the laylines much easier to interpret as they aren’t swinging around as the boat goes over the waves.

Laylines are displayed as solid red and green lines, while an optional dotted line shows historical layline data to inform your decision about when to tack. They can be set to automatically take tide into account, and you can either use a manually-set target wind angle or the actual TWA. You can also upload a polar diagram if available, which will improve the accuracy of the system.

The SailSteer display can be overlaid on the chart.

You can add vector lines for heading and COG, or use the ‘SailSteer’ overlay which displays wind, tide, COG and a compass rose on your vessel. It’s a simplified version of the main SailSteer screen (see panel, p86).

Laylines are enabled via an easily-navigable ‘Layline settings’ menu.

A large amount of data can be displayed on a one- or two-column panel to the right of the screen, including ‘SailTime’, an ETA based on layline distance to sail, distance and time to each layline, which shows which tack is favoured and which will get you there faster.

As we approached the layline and considered tacking, the damped display showed clearly and equivocally when we should tack, with the historical wind overlay adding a useful safety margin in the shifty north-easterly breeze coming off the land.

Downwind, the laylines were equally easy to interpret, showing optimum angles to sail as well as laylines set to encourage you to gybe to bring us to the mark at optimum angle and speed – in our case a pre-set TWA of 145°, although a polar plot would give you a more accurate readout for your particular boat.

B&G

B&G have long led the market in this area, but startline data is currently only available on high-end systems connected to one of their standalone processor units. The Vulcan can’t display startline information, even when connected to a processor: you’ll need to invest at least as far as one of their ZeusTouch MFDs to gain this facility. Processors are available in various guises, from the H5000 Hydra to H5000 Hercules and H5000 Performance, which have increasing levels of functionality. Starting from £1,799, they add significant levels of calculation and accuracy to the system. Startline assistance comes with all of these processors, together with a host of other performance functions beyond the scope of this test, but familiar to nearly every ocean racer of recent years.

Garmin’s startline software was impressive. You can place marks at both ends of the line, either by entering their lat/long or by ‘pinging’ each end – sailing to the mark and pressing a button as you arrive. The startline is then placed on the chart, but the really clever bit comes on the ‘sail racing’ combo screen. This shows a simplified diagram of the startline, with laylines for each end – particularly useful in the pre-start so that you can hit the layline for the committee boat easily without being above the layline and liable to be shut out by other boats. Also useful is a one-minute position line, based on a target speed which you can input. This dotted line shows where you should be with around minute to go. There’s a ‘time to burn’ indicator to show how early or otherwise you are for the start too, and you can enter an offset for the distance from bow to GPS antenna. All in all, this is a useful function that, if visible from the helm, would be an invaluable aid to getting good starts.

There is no line bias information, which is a shame, as the necessary data is all there and available. The race timer, also available on this screen, can be synchronised to the nearest minute, up or down. It links with the software to tell you how early or late you are for the start.

Inputting routes via shortcodes

One other feature that Raymarine have introduced is the ability to quickly input routes via their shortcodes, by entering the ‘routes’ menu and selecting ‘build using racemark IDs’. For instance, Solent racers will be familiar with the shortcodes (4J, 3A, etc) given by the SCRA to racing marks, and these can now be combined into a route by typing in the shortcodes, separated by commas to create a quick route. You can then go through the route plan and mark each waypoint with its rounding direction, which will then show on the chart with an arrow indicating which way to round it.

Instrument pages

Garmin Garmin’s instrument screen can be customised as required, but is useful ‘out of the box’, as seen here. As such, it displays graphs for average wind angle and true wind direction, so they can be monitored for a customisable period of time. Displays show apparent and true wind angle, as well as tidal rate and flow, overlaid on a compass-rose-style overhead view of the boat. Other useful information such as boat speed, depth and VMG can also be displayed, but not laylines. A larger screen would make this data easier to see and understand from the helm.

B&G’s SailSteer screen can be overlaid on the chart, but is also visible separately. This is a compass rose overlaid on the vessel which displays COG, heading, wind data, laylines (both real-time and historical, which appear as the shaded colours), speed, tide and as much data as you want. It takes a little time to get to grips with the screen, but once you’ve familiarised yourself with what each icon means, it provides a useful graphical representation of what’s going on. The central rose is big enough to see from the other end of the cockpit when under way.

Raymarine Raymarine’s sailing instrument page can be customised to display anything that is available on the SeaTalkng network. We selected tide, apparent and true wind, COG and heading, with waypoint information (displayed as the waypoint’s symbol on the compass) also overlaid on the useful ‘dial’ type screen. Laylines are not displayed. The ‘dial’ displays offer a useful interpretation of the data available but, on the 7in screen, we found them too small to steer by and stuck to the digital readouts when viewing from afar. A bigger screen would resolve this issue.

Screen size

Having a small skiff usually means that free dash or console space is an issue so just by considering this you can eliminate almost all the chartplotters with large displays. They will most likely simply not fit. Smaller displays also have the advantage that they tend to be self-contained. Components like antennas are built-in right into the display head. This doesn’t mean that units with bigger screens aren’t recommended. If you have enough space to accommodate them, they will definitely provide a more rewarding experience. Seeing details in the charts will become difficult and frustrating with a small screen. If you wish to avoid having to constantly zoom in and out just to find out where you are, then by all means, go for a larger screen size.

Sonar

If the unit has a sonar on board it’s nice to be also able to accessorize it properly. Some advanced units come with Wi-Fi capabilities to display sonar on smartphones and tablets.

So there you have it, these the are the most important features that you have to keep an eye out for when you go hunting for a chartplotter. To simplify your buying process even further, this article presents the best products that you can rely on when you go on a marine adventure. They are all extremely well-balanced when analyzing the cost relative to their features. Some of them are better suited for those with lower budgets and others will be very appreciated by the seasoned veterans who want something more advanced.

Product Highlights

Garmin is a very appreciated maker of chartplotters and the last unit worth looking at is the GPSMAP 7which is suitable for those with more limited budgets that still want a quality device. It’s not as reliable compared to other devices on this list and the 2.6-inch display is not exactly optimal for looking at the charts, but it does have some interesting features worth exploring.

Due to a high-sensitivity GPS receiver, this device will locate your precise position very quickly. Even during those times when you find yourself in heavy cover and deep canyons, it should be able to maintain an accurate GPS location.

When it comes to the maps it’s important to mention that the base model has no sensors or charts and you might want to look into it and decide which is the right version for you. The microSD card makes it easy to add detailed marine as well as road and topographic maps. If you’re worried about water getting into the card slot, it should be noted that it’s located inside the waterproof battery compartment.

With solid functions overall and portable enough for a variety of outdoor pursuits, this Garmin model is especially recommended for those who need a more compact unit that’s also less costly. The lack of pre-loaded marine charts in the base model can be a problem as you will have to spend more for the version that includes them but the price is still pretty reasonable. It may not be a perfect device but it seems to accomplish its purpose without any glaring flaws so it’s recommended.

Chart Plotters

Changing technology in the recent years has drastically changed the face of modern boating. The emergence of GPS chart plotters has made boating safer, problem free and worth having one of the best GPS chart plotters for smaller boats aboard.

With the best chart plotter, you can comfortably cruise to new destinations and back ashore with the capability of mapping out the water bed terrain. Several factors should be considered before buying a chart plotter to ensure your needs are adequately met.

Simple To Use

No one likes a device that comes with a lot of complicated switches, buttons or a bunch of complex applications that can make any operation a difficult task.

The ease of installation of the unit should also be considered; this means it should not require the need of a particular person to perform the task. Some chart plotters come with easy to read display screens that can still be clearly visible even in bright sunlight.

These well-designed screens are installed with auto dimming screens that can be regulated depending on an individual’s light intensity requirement.

Its out-of-the-box sonar transducer supports 200/77/50 kHz and operates at 500W RMS & 4000W PTP. You will get outstandingly detailed images on either depth and large area. At 7kHz, 73SV spots fish at 2300 ft. in freshwater and 1100 ft. in saltwater.

The GPS module of 73SV is one of the best in its class. The Hz GPS updates position times per second to help you with accurately marking and returning to your waypoints. Speaking of waypoints, you can now transfer them, tracks, and frequently used routes stored on another manufacturer’s or Garmin’s GPS product to your Garmin chart plotter via GPX software formatting.

Worried about the display? 73SV features an 800 x 480 color 7-inch display, which will allow you to keep track of every detail on the area map! It will provide you with data on temperature, time, depth, and alike.

You can chart your course

Even if your fish finder doesn’t have preloaded maps, you can do that yourself with the majority of the modern models by setting waypoints.

You can go ice fishing!

Doesn’t matter whether you are a professional angler or just a passionate beginner, when it´s about getting the biggest fish we all agree that we want the latest, newest and most useful gear with us. Considering your requirement we’re presenting all the best fish finder reviews through this site. After you finish reading this article you will be such an expert that you will want to sleep and kiss your fish like my friend here.

Getting to the point, we know how important it is for every angler to find the equipment that fits them the best. Therefore we have chosen ten (10) of the best Fish Finders in the market that will take your experience to the next level. Since we know not only professional anglers will read this article we would like to give a little overview.

Fish finders are useful equipment that allow the angler to see a graphic representation of what’s underneath the boat to identify or not the presence of fish.

Before you go to any seller and order one you have to ask yourself what kind of Fish Finder you need: standalone, chartplotter combo or network? If you have a small boat, your budget is limited, you are just starting on the angler world and don’t want to risk so much, or you just like to go as old school as you can, the standalone version is the best for you.

It will fulfill the main propose of the equipment which is to let you see what’s beneath the boat, and whenever you want to go bigger is always possible to connect a GPS sensor later to convert it into a chartplotter combo.

The installation of a transducer can convert your chartplotter into a combo unit as well. Read more about the transducer in our “Buying Guide” at the bottom. At last but not least the fully Networked system are suggested for all major suppliers because allow huge range of data sources as are radar, video, satellite radio, raster and vector GPS charts.

Usually this type of equipment allows Bluetooth/WiFi connections and is compatible with Android and IOs. In this same range we can consider the multiple-display network systems that are the perfect match for medium-sized to large vessels.

Now that we have a clear panorama on at least the main three categories of fish finders we can start with our list.

Device Screen

It’s a widespread fact that LCD Displays consist of so called “Pixels” which are nothing more than the smallest controllable elements of a picture on a physical display device. The more pixels are being stacked up on each other (vertical orientation) the higher is the depth oft the resolution.

The amount of Pixels in horizontal orientation determines the life cycle of an Object on the screen before it gets swiped out of the view by gestures supported by modern Technologies like Touchscreens.

A high density of Pixels per square inch result in a better detail of Images and a general improved ‘feel’ oft the Screen. It also allows you to recognize better what’s below you and the split-screen images are also of higher quality. A decent amount of Pixels, screen resolution and screen size make it easier for you to spot air bladders of smaller fishes, fishes on the ground and target individual fishes.

Another important factor is the contrast that your display offers. It has to be sharp and exact for a cleanless identification of your target fish and its separation from mud. All in one you should consider aiming for a device with a good display resolution.

Diagonal measure of screen size

A widescreen display has the ability to display more meaningful information at once. For example you can locate your elements individually or you can use it to run and display the different programs your device offers at once (e.g. GPS, Radar and other Sensor signals).

CHIRP and Broadband fish finders

Broadband fish finders are a modern trend on the market they are also known as Compressed High Intensity Radar Pulse, shorty CHIRP. The difference is that these fish finders don’t operate statically on one or two frequencies like the traditional fish finders.

It sends out a signal on a specific Frequency and swings it up to another predetermined frequency. A CHIRP fish finder differs in its performance from traditional fish finders by having less peak power.

However the advantage of its wide-band frequency technology allows it to transmit long during pulses and therefore put up to 50 times more energy into a water. Because of the application of scientific algorithms like digital pattern matching and signal processing a CHIRP device offers outstanding screen resolution and intelligent target detection. Instead of spotting masses of fishes you’re able to locate individual fishes within its groups.

A depth range of 300-500 Meter is easily attainable with these broadband devices which also offer highest sounder technologies.

Higher frequencies should be used for mid-water depths.

Orientation

It’s important to identify which features you really need. There are devices with high frequency transducers that allow sight into different angles like side, straight down or a 360-degree View.

There are many variants of features which often lead to a confusion in the selection of necessary attributes. For example an inland angler who’s mainly looking for fishes in shallow lakes won’t have any use for a feature that allows you to stare down 2500 Meters.

Avoiding devices with that feature will most of the time save the fisher some money. Instead he should focus on a horizontal-based view. Nowadays you can identify devices that suit your needs by its names like “StructureScan HD” or “CHIRP DownVision”.

In-hull

An In-hull transducer doesn’t require a direct water contact. It’s glued with silicone or epoxy to the inside of the hull. Unlike other transducers it doesn’t work on cored or steel hulls but on stable fiberglass. Just like the transom-mount transducers In-hull transducers are popular on trailer boats.

Trolling Motor

A trolling motor is clamped to the outside or permanently installed inside the propeller hub of the trolling motor. Some models include a built-in 200 kHz transducer that suits a lot of popular fish finders.

Points to be careful

We know that it is really hard to pick the product that fits you the best, so we want to make a little resume on steps to consider when choosing the best fishfinder followed by our useful Buying Guide.

SideVu needs improvement

Powerful Fish Finder With GPS: Humminbird Helix Di is one of the latest best fish finders in the market. It offers a whopping big display of 800×480 resolution. It’s super bright display can be seen at heavy sunlight very easily. This is one of the best fish finders by Humminbird which provides highly accurate data on a big screen.

This powerful fishfinder offers down imaging. Via this down imaging technology, you will be able to see what is under beneath you. High-frequency sound waves are used to create the images which will tell you what’s under beneath you. It gives you the fish eye’s view.

Transducer is slightly tough to install

Cheap portable fish finder: Are you a big fan of portable fish finders like my friend Sara? She likes portable fish finder as she loves to move a lot. This small fish finder is very powerful in comparison with other ones.It is straightforward to use by enabling the power and casting the sonar sensor from bank or boat.

Cone Angle 

Cone angle is significant features to choose the good fish finder for yourself. Assume the cone angle as a point from the beginning of the transducer. It starts spreading from the point and the deeper it goes, it becomes wider. Please note that the more it widens and goes underwater, the more it loses its sensitivity. Usually, the cones range from degrees to 60 degrees. Normally the transducers come with a cone angle of 1to 20 degrees. Most of the time, 20-degree cone angle is good for most anglers.

Most of the transducers have a single beam. More advanced transducers come with dual beam, triple beam, side beam and more. These superior beams offer you the service to cover more water beneath your boat. This option comes very handily when you are looking for fishes in a big lake or river. If you are looking for the best fish finder, try to get a fish finder with at-least dual beam.

Display

The display is another important factor while choosing the best fish finder. If your fish finder has a big screen, it can offer more data easily. Advanced fish finders come with color display along with other features. Advanced fish finders with big color display come with high resolution and great image like pictures of the objects below your boat.

Most of the advanced fish finders come with a GPS option. It is basically included in the device which will help you to find the spot you previously found. This will even help you to navigate through the lakes, rivers or in the ocean. This actually helps to minimize your effort to find the best fishing spot you found previously.

Fish Finder Transducer

When you’re looking around for fish finders online, the display image is often on the console/screen that you look at while in the boat. However, this piece doesn’t really do the “heavy lifting”, rather, another piece called the transducer is where the bulk of the work takes place.

The formal definition for “transduce” is the process of converting one type of energy to another. In the case of a fish finder, the transducer emits sound waves (or “pings”), then receives the returning signal and sends that to the console in the form of an image. Therefore, the transducer is often mounted on a different part of the boat than the console, usually connected by a cable.

Most fish finders will already come with a transducer, so you don’t have to worry about trying to match a fish finder with the correct transducer. However, we do recommend paying close attention to the transducer specs because different water conditions will require different transducer settings for optimal detection of fish and smaller objects. Similarly, perhaps you already have a fish finder and want to change to transducer because you now own a different boat or fish different waters than you used to. In any case, knowing the basics of transducers can really help you feel comfortable in the choice you make.

Transducer Frequency

Frequency is measured in the units “Hz” (Hertz), where HZ means per second. Fish finders typically operate in kHz, so if you see this unit, then you’re looking at the frequency! Some of the most common frequencies you will see are 50kHz, 83kHz, and 200kHz.

If you have been looking for a fish finder already, you may have noticed that often times there is a “/” (slash) between two numbers, such as 50/200. This means that the transducer can operate both at low-frequency and high frequency. The fish finder will either be able to toggle back and forth between the frequencies, or sometimes they can display both in a split-screen appearance.

Low frequency pulses can travel further through water. Therefore, if you are fishing in deep water and want to know the water depth, as well as see any bottom dwellers or snag-prone objects, then a lower frequency may be best in that situation. If the water isn’t too deep, then you may prefer a higher frequency, as the pulses simply won’t need to travel as far. Furthermore, high frequency pulses offer better detail on the screen, and therefore may be better at picking up smaller fish or details about the vegetation in the water. If you’re on a lake with varying depth, type of fish, or water clarity, then it may be beneficial to have a Fish finder with both low and high frequencies available.

It’s tough to know exactly what frequency will be needed for a particular depth because it also depends on water temperature and murkiness (lower frequencies are better for murkier water). The “general” threshold commonly used is 200 feet, whereby higher frequencies, especially a single frequency, may be best suited to water depths under 200 feet. Lower frequencies, such as 50kHz, are likely to be better for water depths greater than 200 feet. But like we said, this is a general guideline and not meant as a written-in-stone rule.

Transducer Power

If you’re on the hunt for a new fish finder, the power, which is basically the strength of the signal being emitted, won’t be an overly important spec to consider assuming you are already considering the frequency. In a nutshell, lower frequencies are typically coupled with a higher power, and higher frequencies are usually coupled with a lower power. Given what we already know about transducer frequency, we can guess that lower power is ideal for reaching greater depths. This is in fact the case, and is why you will often see frequency reported in the product description, but power may be a little more difficult to find. If you are looking for the power of a particular transducer, it will have Watts (W) as the units, and they usually range in the area of 100-1000W (RMS).

One thing to note about transducer power is that while you may be able to mix and match components of different fish finders, mixing components from systems with way different power specs can decrease the longevity of your fish finder. So while it could work in a pinch, and sometimes even improve the quality of the images you receive if you swap to a transducer with a higher power, that may come at the cost of decreased durability.

Transducer Beam Width or Angle

If you’re learning about the different features of fish finders, often times you will see information about the beam width or beam angle of the transducer. This can be considered your area of coverage, or the area you are able to “see” underwater. When the sound pulses are emitted from the transducer, they are emitted in the shape of a cone, whereby the covered area grows larger the deeper the sound penetrates (like an upside-down ice cream cone). Therefore, smaller beam angles cover less area while larger beam angles span a larger area.

The beam width of your fish finder will depend largely on the frequency. The lower the frequency, the larger the beam angle. The higher the frequency, the smaller the beam angle. Low frequency/large beam angles are great for covering a large area underwater and gaining a general sense of where the fish are and how many there are. High frequency/narrow beam angles are great for shallow depths and provide more detail of the underwater environment.

Fish Finder Console

Alright, enough about how best fish finders work, just show me the fish! The console is the part of the fish finder that will map out the depth and display any fish in the area. There is actually quite a variety of consoles available, from black-and-white to color, from a small to the large screen, different resolutions, etc. So while it’s extremely important to focus on the transducer specs, knowing more about the console can increase the chance that you will end up with a fish finder that is perfect for your needs and wants.

Console Screen Size

This is a pretty simple one. Many people like consoles with a larger screen, but they tend to be more expensive as well. Chances are if you’re looking at a fish finder that is relatively expensive and has a large screen, that it may also be capable of displaying more than one image. For example, dual frequency fish finders can sometimes display a split-screen image, but you need a large enough screen for this. So if you’re wondering why it’s so much more expensive for a fish finder with a larger screen, check the more specific capabilities like dual frequency and split-screen display, as that may be a factor as well. However, please keep in mind that a large screen doesn’t have to mean advanced capabilities, there’s just a decent chance that it does.

One thing to keep in mind about screen size, especially if you are looking for a fish finder as a gift, is eyesight. While fish finders are often mounted in convenient locations on the boat, you won’t always necessarily be directly next to it. It can be a hassle to always have to get to the screen, move in close, and squint to see what’s on it, so if any eyesight issues are at play, it’s probably better to lean towards a console with a larger screen.

Console Screen Resolution

Without going too in-depth, there is a little bit of interplay with screen size. Larger screens are usually capable of packing in more pixels, so it’s a good idea to consider both. For example, let’s say we have the one really small screen and one really large screen, both with the same resolution. There will be no difference in the amount of information displayed. The big screen will simply display a larger image. However, let’s say we have two screens that are the same size, but one is high resolution and the other is low resolution. The high-resolution screen will provide more detail than the low-resolution screen.

Down Imaging

On certain fish finders, usually the higher-end models, you may notice they talk about “down imaging”, “DI”, “down view”, or “DV”, or some variation of that general form. This is a pretty cool feature that can definitely come in handy at any time, but especially if you are in an area with lots of vegetation on the sea/lake floor, or if you’re trolling close to the shore.

The benefit of down imaging is that it can provide a much clearer view of what is directly under your boat. In this case, a high-frequency sound waves are sent out in really small “slices” instead of a wide cone. The result is a very clear image that almost looks like a photograph because it provides so much detail, it just cannot cover as large of an area as the standard transducer function. However, these down view images can usually share a screen with the standard display in order to provide a comprehensive sense of the underwater environment around you.

Black and White vs Color Console Screen

Color screens tend to offer better contrast and are often better for identifying fish that are close to other objects, such as the bottom and associated vegetation. Color screens can also sometimes employ higher resolution, which could further assist in this matter.

So when is a black and white display favorable? For starters, if you are on a budget, then you can definitely find cheaper black and white displays. Similarly, if you are a beginner and not really sure what your preferences are or how much you will use it, then we would suggest a basic model learn on first, and this will likely be black and white.

At the end of the day, it’s not only about black and white versus color. All features need to be considered, and perhaps one particularly important feature to consider along with display color is screen resolution. In our opinion, resolution, or “pixel count”, is much more important than the color of the screen. So let’s say you are deciding between a black and white display and a color display. If you notice the black and white display has a higher screen resolution than the color display, then the black and white display could be a good option if you are looking to save some money with the best fish finder and don’t need anything overly advanced.

Display Size

The most expensive model, the CHIRP SI GPS G2, has a maximum depth of 1500 feet out of the box and 2500 feet with an add-on. It has a wide frequency range along with that, meaning this can be considered the best fish finders in the series for its depth range.

Most sonar systems send one frequency at a time. You can look for information from a high frequency or a low frequency, but you cannot look for information for both at once.

Over the course of an afternoon, this can mean missing out on dozens or even hundreds of fish.

But the Lowrance Hook 7 can be considered the best fish finders for people looking for stellar sonar and a series of cool features beyond sight and sound.

As a matter of fact, this feels so high-tech that it makes you think Lowrance should be making technology for James Bond. Anglers can really rejoice in the fact they work for us and not MI-6.

With other fish finders, you need to manually adjust your settings to see fish and other details clearly. With the Lowrance Hook-7, you can avoid that responsibility with advanced signal processing. This feature gets that done for you, making it easier for you to focus on catching fish.

TrackBack allows you to review your recorded history after your journey or on your next one. Everything from structure transitions to fish targets can be reviewed easily.

That makes the Hook-the best fish finders for anglers looking to keep track of their fishing trips after they return.

Fishing Gear Labs

A Global Positioning System (GPS) is an important feature of a fish finder. A GPS will help you locate a fishing ground you previously marked without much effort. Not only this but it will also help you navigate through the waters easily. With a GPS fish finder combo, you can fish even in new environments and still chart your way home. However, not all fish finders will come with a GPS option, so you need to make a right choice when buying fish finders.

Speed Sensor

In most cases, this functionality will come built in the GPS system. It will help improve your fishing efficiency as you will know whether you’re moving at the right speed for a particular type of fish.

Power is an important consideration when choosing a fish finder. In depth finders, power is measured in watts. A good fish finder should be powerful enough. High wattage means the device will show faster and accurate readings. The best fish finders have a minimum wattage of about 600 watts. However power will also depend on the depth of fishing, shallow water requires less power compared to deep waters.

Uses Patented WiFi Signal Technology

Lowrance 000-12635-00Hook-3X Sonar

Lowrance Hook 3X Sonar is another top quality fish finder that features a 3.5-inch LED-backlit color display with wide viewing angles. This intelligent device can identify fish targets, structure detail, thermoclines, bottom contour, bottom hardness, and more. Plus, it supports a dual-frequency operation to generate an accurate view beneath the surface of your boat. Take a quick look at the major features of this fish finder.

Powerful Transducer with In-built Water Sensor

The model features a powerful transducer with a built-in water-temperature sensor that can track bottom upto 75mph. It 3.5-inch clear and lucid screen displays fish icons so that you can easily identify fish targets and catch them gently.

Wireless Bluetooth Connection

You do not need to use your mobile data or a Wi-Fi internet connection at your fishing spot! In fact, the Deeper device comes with a powerful internal Bluetooth access point which connects to your tablet and smartphone.

Dual Frequency Operation

Featuring a dual frequency operation, this excellent fish finder offers twofold area coverage. For an instant, you should use the narrow beam or 290 kHz (15) for higher accuracy scans of the bottom structure. Whereas, you can use wide beam frequency or 90 kHz (55) for an extended search area.

Mobile or Fixed

For more settled fishers and watercraft owners, a much better option is a fixed unit that they will be able to mount at any precise location on their ship. In accordance with your preference or needs, it is possible to mount the transducer either on the stern, hull or trolling engine.

Considerations when researching new echo sounders

Because today’s echo sounders and transducers are manufactured to the highest technological standards, it is difficult to make comparisons between the different models within the same price range. This is because they generally use similar technology and have similar screen view presentations, operating functions, frequencies and settings. The only real difference is in the menu systems.

Screen view options  Full screen view showing the complete water column from the bottom to the surface.  Split screen view with each side showing a different section of the water column, using a bottom follower.  Full screen View Bottom Lock.

Often this is no major issue because echo sounders specifically designed for fishing usually feature a range of screen view options that allow the operator to enlarge, expand or zoom any section of the water column within the display screen.

Some examples of the situations described above are shown in screen captures hereabouts, which are acoustic images of fish and bottom structure, using different screen view presentations commonly found in echo sounders designed for fishing.

Some fishers prefer to use the seabed bottom-lock function even in calm conditions; I am also one of them. I commonly use the bottom lock display when fishing rivers, to obtain information about the nature of the bottom; this can be achieved by closely observing the changes in the bottom echo signal below the bottom lock line. An amazing range of information about the nature of the bottom can be obtained from this function.   Viewing a section of the water column using depth range function. The column to right is the A Scope.

Transducer power output and frequency selection

For example, if you are fishing in a depth of 200 meters and your beam angle is 4degrees, the transducer’s detection area, directly under the boat, will cover an area of approximately 15metres in diameter.

Lightweight

Due to the fact that you need to carry this device from one location to another location. And then, you will also carry other stuff. So, prefer a light fish finder device.

This has something to do with the transducer, which features a sonar system. It is through the transducer, where you can get further information from the underwater creations. It varies from to 2degrees. Wider angles allow you to see more of the area under the water.

Playing the Field

The Garmin 547xs in our test was pinging through the depths with 200/50 kHz.

The Humminbird 587ci HD DI Combo features Down Imaging, and was the least expensive finder in the mix.

Our second batch of technology focused on down-looking scanners/imagers, which operate on a much higher sonar frequency to paint a picture of what lies below with vastly enhanced detail. In a nutshell, high-frequency sonar waves are much more sensitive than the lower frequency waves used by traditional fishfinders; the down-side is weaker depth penetration. Here’s an easy way to picture the difference between high- and low-frequency sonar waves: think of them like the ripples in a pond. If you toss a pebble into the pond, it sends out a series of small, tight, fast-moving waves which are easily reflected back. These waves are like those produced by high-frequency transmissions. But if you throw a boulder into the pond, it makes larger, slower, widely-spaced waves. Those large waves will go a lot farther than the pebble’s ripples—but they’ll also roll right over small items, instead of being reflected back. These are your low-frequency waves. In other words, your traditional 200/50 kHz fishfinder takes a far-looking X-ray, but your higher frequency 455/800 kHz scanner takes a short-range MRI.

Out of the Lab and On the Water

The rigging process proved to be quite educational, exposing a few high points and low points that may not be related to technology, but which I’d certainly want to know about if I were buying one of these units. For starters, the Dragonfly’s mount looks slick and curvaceous, but it’s too flimsy. It’s also a bear to get the unit into and out of the mount, and frankly, I think they should replace it. The single-plug connection, however, is easy to rig and looks clean. The Garmin, meanwhile, feels plenty sturdy and sits securely in its mount. But the plugs don’t twist-lock into place. You simply push them in—over and over again, because when you adjust the unit, a plug sometimes falls out. The Lowrance’s plugs do have a twist-lock, and in my opinion are second only to the Furuno in ruggedness. In fact, the Furuno is over-built in every way possible, from the huge sturdy plugs to the stout mount to the heavy casing. If I had to bet on which unit would stand up best to long-term use and abuse, this would be the one.

For the shallow water test I headed out into the South River, a Chesapeake Bay tributary that’s about 25’ at its deepest. The first stop was a creek where there were some eelgrass beds, because the manufacturers of scanning/imaging units often claim their units are much better at picking up wispy targets like weeds—an ability that’s quite important to some anglers. And from what I saw on-screen, those manufacturer claims are correct. The scanner/imagers showed the grasses clearly. CHIRP-light picked up slightly less conclusive returns. I could tell there was something there and with experience I think I’d know the difference between weeds and whatever, but the picture wasn’t as crystal-clear. Meanwhile, the traditional frequency units pinged right through the grass without showing it on-screen. But the real shocker came when I went over a tree branch. Both scanners showed it laying on the bottom in amazing detail and I could clearly see the branches shooting off the main trunk. The Dragonfly also showed it, though in a bit less detail. The traditional sounders, however, showed just a red streak breaking slightly off of the bottom. You could tell something was down there, but you’d never identify exactly what.

Though it was impossible to get identical shots from all of these units at exactly the same time and place due to the motion of the boat and interference between the units, this stock screen shot gets the point across. Detail levels with the scanner/imagers, seen at right, is greatly enhanced.
