Choosing the best chartplotter

When shopping for a marine GPS chartplotter, one of the most important considerations to make is your financial situation. The price of these useful devices might vary substantially depending on their size and the features they incorporate. The establishment of a budget will not only help you cut down your possible choices, but it will also assist you in determining which features you absolutely require and which ones are only good to have.

Dimensions and display

The majority of marine GPS chartplotter reviews agree that screen size is important, particularly when it comes to navigation. Even if there are tiny-screen models available, it is crucial to understand that this also means that the unit has a small screen. Compact variants are ideal for usage in tight places. You want to select a marine GPS and chartplotter with the largest display possible that also falls within your budget in the majority of circumstances. Larger screens not only make it simpler to read from a distance, but they may also display more information at the same time. It is generally recommended that the screen be at least 5 inches in size, unless you intend to spend the most of your time crouched over the gadget rather than really fishing.

Apart from opting for a larger screen, you need also consider the pixel count, which will define the resolution of the display. Higher pixel counts result in a picture that is sharp and bright, and is therefore generally easy to read. It is feasible to get reasonably priced GPS/chartplotters with a screen resolution of 480 x 480 pixels, despite the fact that higher resolution screens will increase the price of the device. This guarantees that the maps and charts, as well as any fish that have been spotted by the transducer, can be seen clearly at all times. If you can afford it, you might also want to consider an LED display with backlighting, which will allow you to view the screen clearly even in low light.


Because you will be using the marine chartplotter on or near the water for the majority of the time, it is critical that it is constructed from a sturdy material. In general, most models are made of plastic, which is rather lightweight and durable, and can withstand the occasional tumble in the water. When comparing the many marine plotters available for purchase, it is critical to search for the IPX or JIS ratings. This refers to the International Protection Code and the Japanese Industry Standard, both of which assign a water resistance rating to various products. Because they are both based on the same fundamental standards, either rating will provide you with the information you require.

There are some low-cost marine plotters with a rating of 4, which is essentially deemed “splashproof.” This indicates that the gadget can withstand a few drops of water on it without short-circuiting, but it will not survive being on the water for an extended period of time. For those on a tight budget, a marine chartplotter with a rating of 5 or 6 is preferable, as this indicates that it can resist periodic splashes and sprays of water but cannot be immersed. It is likely that you will want to invest the extra money on a unit that has a rating of 7 or 8 if you frequently fish in rainy weather or on rough water. A “7” indicates that it can tolerate being submerged for up to 30 minutes, while a “8” indicates that you shouldn’t be concerned about anything. For the sake of affordability, it may be necessary to sacrifice some features in order to obtain a chartplotter with a higher rating. When it accidently falls into the water for the first time, you’ll be glad you took the precautions.


When determining the appropriate power, it is also necessary to consider the transducer. Typically measured in watts, the power has an impact on the depth capacity and accuracy of a device’s depth capacity and accuracy The majority of the time, if you are fishing in water that is 200 feet deep or less, a marine chartplotter that produces between 100 and 300 watts would suffice. There are some chartplotters that come with a transducer, and the wattage of the transducer will decide how far the sonar beam can go. The size of the transducer crystal will also be important because it has the ability to multiply the power.


Many fisherman overlook the need of connectors, at least until a fire breaks out on the water, and then they realize their mistake. It is not recommended to use plastic connectors for electrical devices if you plan on disconnecting the device on a regular basis. Although most chartplotters are equipped with plastic connectors, metal connectors are meant to survive a little longer.

Antenna ports are among the several types of connectors to take into consideration. This can be particularly essential if the device also has GPS capabilities built in. Although having an inside antenna is convenient, reception is not always the best, and information transmission is frequently delayed as a result of this. An external antenna will give you with a consistent signal, allowing you to receive weather updates and maps information as rapidly as you would want. An additional feature to consider is a USB port or SD card slot, especially if you intend to save and exchange data or connect to a computer.


Q: How does a marine chartplotter work?

The fact that you are wondering what a marine chartplotter is or how it works means that you are not alone. These devices are intended to display charts or maps of the water on their screens. In case you’re in unfamiliar waters or looking for something special, such as a hot fishing spot, sunken wreck, or great diving spot, this can be quite beneficial to you. Your boat will appear on the screen, and all you have to do is guide it in the direction of the course plotted on the chart. This should also provide an answer to another frequently asked question, “what exactly does a maritime chartplotter do?”

Q: How to use a marine chartplotter?

Thankfully most chartplotters are designed to be incredibly easy to use. Simply turn it on and wait a couple of seconds for the GPS positioning satellites to lock onto your signal. Once your device has been located you will see your position marked on the chart and you simply follow the course shown. Most screens will continuously display your longitude and latitude so you can easily tell if you start to drift off course. If you are wondering how to set your course that is also pretty easy.

Simply enter your destination and let the chartplotter do its work. Some models come with touch screens so you just have to tap the display, while others use directional arrows to move the cursor where you want to go. Once the destination has been entered the chartplotter will find the best course for you. To get back to the marina simply choose it as your destination.

Q: Who makes the best marine chartplotters?

It’s hard to decide which marine chartplotter is the best, especially when some of the manufacturers are top names like Garmin and Lowrance. These companies are responsible for some of the best units, especially when it comes to combining functionality and ease of use. Another manufacturer to consider if you are looking to replace an old unit or buy your first one is Furuno, as many of these chartplotters have great water resistance ratings. Raymarine is another recognizable name, and many of their devices are also priced with the budget conscious consumer in mind. Simrad is also gaining notice for its marine chartplotters, especially for accuracy and durability.

There are other manufacturers of chartplotters that are worth considering and if you want to find the best one for you it might be worth it to do a little research on your own.

Q: Even though I’ve read all about it on the internet, I can’t seem to figure out how to use a marine chartplotter. Can you give me some tips?

It all depends on the model you have chosen. We can give you some general pointers; however, we can’t tell you exactly how the unit you’ve purchased needs to function or how you’re supposed to utilize it as its interface might differ from the models we have come across. If what you plan to do is navigate in close-quarters, it might be a good idea to zoom in as much as your device allows you to. This practice can help you avoid getting deceived by the info displayed. If you’re on your boat and intend to engage in some long-distance navigation on open water, you should pay attention and try to set up a waypoint or at least select it so that you’re safely guided toward it. Despite their reliability, marine chartplotters stand no chance when compared to a good old compass, as it can get you out of a tricky situation if the battery has run out or if you have no means of powering up your device.

Q: How does a marine chartplotter work?

The simplest way of answering your question is to tell you that chartplotters can tell you the exact position of your boat on the chart displayed on the screen. This way, you’ll be able to determine your location without finding it hard to understand the data. Any chartplotter comes with one map or the other, depending on the area you live in or plan to do your boat fishing in. In a nutshell, a chartplotter works much like a GPS navigational unit that you might have in your car. The difference between the two is that the chartplotter can also display charts on the screen. As we were saying before, this makes it easier for you to tell where you are.

Q: Should I get a new or a used marine chartplotter?

Most marine chartplotters tend to cost a pretty penny, especially if you go online and check for prices for new devices. That’s why many anglers are wary of such an expense. Despite the fact that manufacturers have a set of tricks when it comes to attracting potential buyers, every second-hand purchase is risky. On the one hand, you can’t be sure that the prior owner of the device has treated it with care. What’s more, if you’re going to buy an older model, you might have to at least consider doing a bit of research to see whether or not it’s compatible with the maps and charts you can download for free online. It’s difficult to check for faults when buying a used marine chartplotter, so we recommend getting a new one.

Q: I’ve done a bit of research on my own and I keep noticing that Garmin seems to make the best marine chartplotters. Unfortunately, most of the units I’m considering are way too expensive for my finances. Do you think I should save some money and get one or choose a cheaper model?

By all means, you should try to devote a part of your budget on a monthly basis so that you’re able to get a high-quality chartplotter manufactured by a trusted brand. Whether you choose Garmin or some other company in those lines, the fact of the matter is that you’ll be able to benefit from the brand’s return policies and other perks. Cheaper models will always be available, but it might be a good idea to stay away from them as they might break down and force you to spend more money in the long run to replace them.

Garmin 010-01524-01 echoMA

This Garmin variety might just as well be the best marine chartplotter, considering the amount of appreciation it has acquired over time. It’s simple to use and easy to install and features one of the most capable screen displays in the industry today.

Garmin has been building marine electronics for quite a while now, and so the company is well-known for developing top-notch products. This is the exact case of the Garmin 010-01524-01, as it does what it is supposed to do and does it well.

The model has a built-in 5 Hz GPS antenna that makes updating and setting waypoints as easy as pie. Additionally, the chartplotter manages to combine the capabilities of a DownVü scanning sonar and the ones of a traditional HD-ID sonar.

The pack contains the actual chartplotter, a quick-release mount, a flush mount, the GT21-™ transducer, a transom mount, a power cable, user documentation, and hardware.

This Garmin variety has been granted only positive ratings, which brings us to the conclusion that it might be worth considering if you still have not made up your mind.

Lowrance Elite-4m HD

Both the design and the price of this item suggest that it is destined for the people who are not willing to break their entire budget over buying an expensive marine chartplotter. All things considered, if you’re a beginner and have little to no experience in choosing fish finders, this one might be the best alternative to consider. In fact, it has gathered just positive reviews, so it’s definitely worth the money. The Lowrance Elite-4m is a tad older model that features a 4.3-inch backlit display and a built-in GPS antenna, complete with Navionics Gold cartography. The unit has a detailed US map that includes over 3,000 coastal contours, lakes and rivers.

As is the case with other products in the line, the Lowrance model is water resistant.

Let’s see what buyers had to say about this variety. Some characterize it as being a great budget chartplotter, while others state that it’s worth the 5-star rating they’ve given it. An Amazon customer claims that the screen resolution is exceptional.

Lowrance HDS-9 GEN3 

Lowrance chartplotters and fish finders have been known to take the game to a whole new level as the company seems to be focused on developing new technologies that can give a helping hand to anglers out there. When it comes to ease of use, this unit is a clear winner as it will help you get the most out of your fishing trip without being bothered by various technicalities.

Since it is equipped with a 9-inch touchscreen, this model can offer you the freedom to choose the way you can use it. As such, you may either enjoy the multi-touch or the full key pad operation, depending on your personal preferences as well as the water conditions that you might do your angling in.

The neat thing about this unit is that it combines Structure Scan HD sonar imaging with CHIRP sonar technology, so you can get all the information you might need in regards to the bottom structures and the areas around you.

Another detail that you are likely to appreciate about this product is its screen as it is backlit and can shine brightly both during the day and at night. The display is an improvement for older generations of chartplotters in this series.

Garmin GPSMAP 536s 

This 5-inch chartplotter came up second on our list, and that’s because it is not as cutting-edge as others. Compared to some Lowrance models that cost over one thousand dollars, this particular device has been outfitted with a somewhat smaller screen and requires a bit of more work on the part of the person using it. As such, it does not boast a touchscreen, so you’ll have to rely on using the buttons placed on the side of the chartplotter.

The neat thing about the GPSMAP 536s, however, consists of the fact that it has been NMEA 2000-certified, which means that it works perfectly with other Garmin devices in this category. It’s both radio and weather compatible.

A dual-frequency transducer is included in the deal, so you needn’t worry about spending a penny more. Therefore, as is the case with other products we have analyzed, this particular one meets the needs of anglers by allowing them to use it both as a chartplotter, a GPS, and a fish finder.

The user feedback about the built-in maps of this unit is somewhat confusing as some say that they have helped them a lot whereas others claim that they are useless.

Furuno GP1870F

If your budget allows it, you can check out less affordable variants as the Furuno 7-inch one. The neat thing about this unit is that it is both a chartplotter and a fish finder. Other than that, it specs do not greatly differ from the ones of other high-end models we’ve analyzed. Yet the model does come with a large 7-inch LCD that is backlit and bright enough to be readable even in direct sunlight.

The mapping system of the Furuno alternative is a basemap, but the model has a SD card port which can be utilized for loading extra maps.

The Furuno is a dependable fish finder that is waterproof, durable and compact, as attested by some of the reviews we’ve gone through. To make installation a breeze, the manufacturers have made the GPS antenna of this variety internal.

The memory of the Furuno allows users to set up to 30,000 waypoints and up to 1,000 routes.

This model is capable of discovering and displaying fish of which the length is between 4 inches and 6 feet.

Garmin GPSMAP 640

For years Garmin has been one of the leading manufacturers of GPS units for vehicles, so it only makes sense that they would be able to design a high quality marine chartplotter. This sturdy device comes with GPS and chartplotting capabilities so you can use it in your vehicle and on your boat. Find the best route to get to the marina and then use the GPSMAP 640 to plot a course to your favorite hot spot. Since it only weighs a little over a pound it is also convenient and easy to carry.

It comes with a 5.2 inch diagonal color display that is easy to see at a distance. The diagonal design of the screen allows it to hold more information without overcrowding, even when you are looking at the map and the marine chart side by side. You will also love the touch screen functionality that makes navigating the menu quick and easy. For additional help, the GPSMAP 640 also comes with a handy instructional manual. To ensure that this marine chartplotter will last for years it even comes with a protective cover.

EchoMAP CHIRP 53cv US Lakes Xdcr

It is possible to learn more about what is in the water and around the boat by using this tiny alternative. The high-frequency sonar can provide you with visuals that are so accurate in terms of detail that they appear to be photographic photos in some cases.

It is possible for the CHIRP sonar to transmit a continuous sweep of frequencies in order to give you with new information that is streamed live. The maps that it comes pre-loaded with cover no fewer than 17,000 lakes in total, 13,000 of which are in high definition (HD).

Your location is constantly updated by the integrated GPS, which can assist you in returning to certain locations quickly and efficiently. This particular model consists of two sonars: the 2D CHIRP, which has a maximum depth capability of 2,300 feet, and the ClearVü CHIRP, which has a maximum depth capability of 1,100 feet.

This option is equipped with a CV22HW-TM, a four-pin transducer that produces two separate power outputs of 600 and 500 Watts, respectively. In addition, the product can perform solar-related activities such as bottom lock, data graphing, sonar recording, rewind, and other features.

In order for the sonars to provide the angler with the best possible reads, the boat that you are utilizing must not cruise faster than 30 miles per hour. If the boat is traveling at a faster rate, the data may not be accurate.


This fishfinder, which has one of the most extensive internal libraries of lakes in the industry, with over 17,000 highly precise maps, might be a lifeline for anyone who is going fishing in a new region.

Beginners will find it particularly handy for both navigating and fishing, as it is incredibly user-friendly and easy to navigate.

There are only a few real-time sonars that can compete with the great definition provided by the most recent CHIRP technology, so you can easily spot both large and small fish schools using this outstanding high-frequency sonar.

You will have no trouble navigating with this high-quality GPS device, and it will keep you on the prescribed path regardless of the weather conditions, allowing you to make the most of your fishing excursion.


While the working speed of the transducer has not been raised as a source of concern, some customers have expressed concern about the speed at which it operates. While this does not affect detection in any way, it may cause some issues for high-speed boats that require accurate real-time transducer readings.

Buying guide

Nowadays, it’s difficult to get the right value for the right money. The market is filled with some of the best fish finders ever have been manufactured, which is why customers can often times end up feeling baffled. Which unit should you pick? If you’re having trouble separating the wheat from the chaff, it might be a good idea for you to check out the following short buying guide. Remember, always correlate your needs to the specs of the product you intend on buying.

Power and frequency

With fish finders, power and frequency always have to be correlated. In deep, murky waters, frequency might prove to be more important compared to wattage. That’s why with wattage, the matter’s actually pretty simple: the higher it is, the better. Dual frequencies are great for individuals who want to fish in deep and shallow waters, depending on their momentary preferences.

Battery life

Once you’re out on the lake or at sea, you want to know that your chartplotter is capable of working for as long as possible. Since manufacturers occasionally leave out this particular detail from their product descriptions, we recommend going through some consumer reviews.


Some fish finders don’t include the transducer in the pack. Pay attention to this detail if you’re looking for the right cost-to-benefit ratio.
