marine gps Buyer’s Guide

If you keep the before points in mind, you can easily go out to the market and buy marine gps, right? No!


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.


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


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.


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.

Man overboard button. If someone falls off the boat, hit the man overboard button to mark their position on the map.

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.

OTW Staff

In 2017, 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.


Garmin has added several new chart plotters and combo units to their popular GPSMAP product line, the 74and 94touchscreen chart plotters, and the 104and 124keyed chart plotters. Available with and without built-in sonar, they are designed for the budget-conscious customer who desires premium features. They are compatible with Garmin’s new Fantom Doppler/MotionScope radars.


The ICOM M93D VHF marine transceiver with GPS and DSC offers watts of output power and up to nine hours of battery life. It features a large LCD display and a redesigned flat keypad. The handheld floats and comes with dual/tri-watch function and 50-waypoint memory.

Fusion StereoActive

Fusion’s portable, waterproof, floating watersports stereo offers built-in Bluetooth audio streaming, AM/FM radio with weather band, and USB audio playback. Boaters and kayakers can easily attach the unit anywhere on board with the Puck-It mount system.

Anglr Tracker

Connect your fishing rod to the “Internet of Things” with the ANGLR Tracker, which seamlessly auto-logs entire fishing trips while you enjoy the day. Use it to track every cast and every catch, and then understand your key patterns of success.

Vexilar SonarPhone T-Pod

The SonarPhone app connects via Wi-Fi to the T-POD, an ultra-portable Wi-Fi transmitter system that has a self-contained battery and can be pulled behind your boat or cast from shore. Turn your smartphone or tablet into a fully functional sonar system that works without cell phone coverage—the SonarPhone creates its own Wi-Fi hotspot and you can share your signal with as many people as you wish.

Humminbird 409460-688ci HD DI

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.

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 25color TFT screen gives a clear image that can give you readings of depths of up to 240 ft. The charge of the unit can last up to 30 hours. It features SideFinding sonar that gives accurate readings. Its benefit is that you can point it in any direction and get full coverage of the area to find more fish. The temperature feature is included.

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 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.


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.

What is Handheld GPS

You know GPS is the Global positioning system which help us to find the target location on the land of see or land of soil. To get pinpoint location which device or network system help this is the handheld GPS. This is the easy to carry.

Accessories & Gear

So you love to go fishing on your kayak? A lot of people does. Some even use trolling motor to go to remote lakes for fishing on their beloved kayak. Everything sounds ok, till you get lost in the remote area.

This could be a nightmare if you don’t know the way back home or if you don’t have an active GPS system with you. If you are kayaking on a remote area or you are just new to the place, a kayak GPS would be very helpful on such occasions.

Even though I am well aware of the places I visit, I always bring a kayak GPS to face such accidents. So if anyhow I forget the way back to home, I will just open the GPS system and get back easily. Sometimes I mark my favorite fishing spots on the GPS, so I can always come back later to the same place to stow the biggest fish on my kayak catch cooler.

For battery purpose, you can use either the rechargeable NiMH pack (which you need to purchase separately) or with the traditional AA batteries.


You will find different GPS devices with different display sizes. The resolution will very upon devices. A good resolution will allow you to see data more clearly. A kayak GPS might be between 2.inches to 5.inches. A small screen would be hard to read, while a big screen GPS device would be hard to carry. My suggestion is to choose a GPS device with 3.inches to inches. Thus, you get to see the data more easily and quickly.


An equally important factor to consider is the build of the chart plotter. These gadgets are designed for use in marine applications which means that the gadget may come into contact with water at any time. Ultimately, it is of paramount importance for anyone buying a chart plotter unit to ensure that the unit is constructed durably.

To determine the water resistance capabilities of a unit, one should look out for the International Protection Code (IPX) or Japanese Industry Standard (JIS) ratings. A rating of is considered resistant to a few drops of water while a rating of between and six is seen as resistant to splashes and sprays of water. However, such units cannot survive submersion.

Many experts recommend getting a unit with a rating of at least or Anyone looking for higher ratings of between and eight may have to spend a little bit extra to get these units. Units with a rating of can withstand as long as half an hour of submersion. GPS units with a rating of are considered the most water resistant. The construction of the chart plotter is critical as it determines the durability and longevity of the gadget.


This is perhaps one of the most critical factors to consider when looking for chart plotters. As noted in the above sections, the prices of marine GPS units often have significant differences based on the size of the unit and even the features included in the unit. The more complex the chart plotter is, the more expensive it is.

Power and Transducer

Chart plotter shoppers must also factor in the power of the gadgets in question as well as the size of the transducer. Power is stated in watts, and it plays a huge role in determining the depth capacity as well as the accuracy of the GPS unit. For example, chart plotters of between 100 watts and 300 watts are ideal for anglers fishing in waters that are at most 200 feet deep.

Transducers are electronic devices whose core function is to convert energy from one form to another. In chart plotters, larger transducer crystals are considered to have more focused beams. Subsequently, this allows the beam to penetrate deeper into the waters.

Electrical Connector

Most people tend to overlook connectors, yet they are extremely important. A connector that is made from plastic or even thin metal prongs is likely to break or bend quite fast. Further, replacing these connectors is in most cases, a costly affair.  It is important to ensure that it is tough and durable, considering the constant plugging in and out of the connector.

Additional Features

Thanks to technological advancements, modern chart plotters often come with a wide array of extra features. For example, while many units have inbuilt antennas, there are those who have external antennas or antenna ports. These are highly preferred since they have stronger receptions as well as enhanced mapping and weather forecasting capabilities.


GPS receiver and HotFix™ satellite prediction both of which enhance the ability of the device to locate the user’s position conveniently and accurately even in rough conditions such as heavy cover.

Garmin Connect ™ allows users to not only store but also review their activities and even share their experiences on social media such as Twitter and Facebook.

The device also allows users to add maps either using preloaded microSD cards or through BirdsEye ™ satellite imagery. However, for the latter, the subscription is required.

This model contains a 77/200 kHz dual beam transducer and the brilliant DownVü capability. The dual beam transducer is very powerful and offers 500 watts that is efficient enough down to 2.300 feet. Also, this unit is known for its precision and dependability, and current owners give this fish finder two thumbs up. By using the Echo, you will enjoy excellent target separation and an exceptional view of the structure of the bottom. The sonar is able to deliver photo-like images of everything below your boat. It will brilliantly portray photograph image of the bottom and every object under the water surface.

You will find so many awesome qualities of the Echo 551dv, and this is one of Garmin´s best-selling portable fish finder on the market today. The awesome Utra scroll feature was designed to deliver reliable information when you are traveling fast.

Another highlight is that you can set the finder to lock the bottom, meaning that you will always see the bottom on the screen. Moreover, there is the Smooth Scaling feature that works to deliver consistent information when you move from deep to shallow water or vice versa. There is also an adjustable depth function that shows you, clearly on the screen, detailed depth of every object below the boat. A white-line identifies if the bottom structure is soft or hard and together with the AutoGain innovation, the gain settings are adjusted automatically to ensure that the sonar only returns top quality and reliable information.

Overall, this unit is receiving raving reviews from users all over the country. Here we have a fantastic, portable and efficient fish finder that was built to last. It is water resistant to ensure top performance in all fishing conditions. Also, there is no need to be glued to the screen at all times, as this model comes with an audible alarm to let you know of any activity near you. It is very easy to mount this device to any boat using the quick release swivel/tilt along with the transom mounts. If you prefer to mount to the dashboard, you can invest in a flush mount kit separately.

Next up is the fantastic Fishin Buddy MAX DI from the Humminbird family and here we have a fish finder that is full of surprises. The Fishin Buddy is extremely compact and fits easily in your pocket. If you have a small boat, kayak or you need to move from one lake to another, this would be an excellent solution for you because it hardly takes up any space.

Moreover, it features the awesome DownScan Imaging feature that provides photo-like graphics of everything bellow the boat. Also, it includes a Dual Beam Sonar with 2400Watts PTP. Although this unit is extremely portable, it features only quality and solid materials. This is a durable fish finder that works flawlessly in any weather condition as it is weather and waterproof.

The installation process is very easy, and you should be up and ready in amatter of seconds, even if you are not the typical tech-person. If you are a complete beginner, you might have to refer to the instruction manual to understand how to identify fish, but for anyone, this is just a few minute process.

Special editions

The Apple Watch Nike+, Apple Watch Hermès and the Apple Watch Edition all have the same internals and specifications as the Apple Watch Series 3, but have distinct aesthetic appearances. And you can choose between aluminium and stainless steel for the case of the Apple Watch Series 3.

The Apple Watch Nike+, which is made from aluminium, is aimed at those who love running and are looking for a sport-orientated smartwatch. We see the Nike+ as an Apple Watch Sport replacement.

The Apple Watch Hermès and the Apple Watch Edition are both aesthetically different to the standard Series 3 watch, too. The Hermès is made with stainless steel, with a unique strap and a Hermès stamp on the back, while the Apple Watch Edition is made with white ceramic, giving it a unique design. Both of these watches start at more than £1,000, and are only available for the cellular model.

Apple Watch Series vs Apple Watch Series 3

If you’re not looking for the latest model, there’s the Apple Watch Series 1, which is a rebadged version of the original Apple Watch that has a new upgraded processor.

The Apple Watch Series 3 features built-in GPS, optional cellular internet, a faster processor, a faster wireless chip, IP6water and dust resistance, a 50 percent brighter screen, and a barometric altimeter – as you can see, there are plenty of improvements compared to the Series 1.

Both the Series and Series 3 come with a dual-core processor. It’s important to note, though, that the Series comes with a S1P dual-core (not to be confused with the single-core S1), while the Series 3 houses an Sdual-core processor, which should deliver substantially faster performance.

Looking at the materials used, the stainless steel version of the Series 3 has the sturdier sapphire glass screen, while the Series is protected with Ion-X glass. It should be noted that the aluminium models of the Series use the same Series glass material.

Price-wise, the Series starts at £249, while the Series starts at £32for the regular model and £39for cellular. Prices increase when you start changing size, straps and materials, though it’s worth noting that the Series is only available in Silver or Space Grey aluminium.

There is only the Sport Band available for Series models, but if you want a different strap you can purchase it separately, but that will of course cost you a few more pennies – all the same straps are compatible regardless of your watch model.

Given the price difference of just £80 between the Series and the base Series 3, it’s hard not to recommend the later model. It’s not only faster, but has several features the older model is lacking, is available in more colours, and will enjoy Apple software support for longer – it’s a better bet unless you really can’t stretch your budget beyond £249.

The straps are

Each of these is available in multiple colour options, which vary according to the model of Apple Watch you’ve selected.

There are some nice third-party straps out there too. We’ve collected our favourite first- and third-party Apple Watch straps in a separate feature on the best Apple Watch straps.

Lowrance Electronic

A manufacturer of consumer sonar and GPS receivers as well as digital mapping systems, Lowrance Electronic  is best known for its High Definition Systems (HDS) and add-on performance modules which include Broadband 4G Radar, StructureScan with SideScan and DownScan Imaging.

It has been a leader in marine electronics since it invented the first consumer sonar device in 195Extremely easy to use yet packed with the features anglers the world over know and love, Lowrance continues to set the bar for the best recreational fishing technology.

There are so many models these days that offer additional feature for your convenience. The best way to go about the specific feature is to identify what you need when you are out in the water. Surely, there will be a device or two that offers solutions to your requirements.

Didn’t Like

This is one of the most budget-friendly handheld GPS devices that I found. Despite being cheap, however, it is pretty durable. An interesting feature that is unique to this device is its monochrome display that adjusts automatically in different light conditions.

This may seem like a backward thing, but I personally find this feature refreshing and super easy to use. This 2.inch-screen navigator has a built-in worldwide base map, and is supported by GLONASS and HotFix, which make it accurate and reliable.

I highly recommend it for its sunlight-readable display and expanded memory of up to 8GB. It also comes with other handy features that I normally do not require, but are pretty useful now that I consider it such as its capacity to wirelessly receive alerts, texts, and emails.

Its quad helix antenna makes connectivity faster and more accurate. Plus, I think it looks really cool with it. More importantly, its software allows you to view and organize maps so you can organize your trips ahead.

Again, it all boils down to what your fishing plans are. To be honest, most of these devices offer more than you need so that the manufacturers can justify the price. Therefore, if you are looking to save some money, be specific with your requirements and consider the features as described in this review.
