Buying Guide

Purchasing the best marine GPS chartplotter is considered an investment that should benefit you for years to come, so you want to ensure you are making a choice that is going to serve your needs long term. To determine which is the best marine GPS chartplotter, there are many features to consider and you will want to work with a budget that makes sense for you as well. With the right mindset, selecting a chartplotter does not have to be stressful!

Understanding what a marine GPS chartplotter is

Marine GPS chartplotters differ from traditional GPS devices in several major ways. These advanced features have proven essential in modern boating, and many do not wish to go on the water with a chartplotter on board.

Marine GPS chartplotters feature a traditional GPS system with the added capability of showing charts. This chart plotting allows you to monitor the position of your boat, where your boat has been, and where your boat is heading! It makes navigation much easier.

Due to this functionality, many rely on the chartplotters to locate, mark and find favorite spots. They are also used to find your way back to your original locations and note various objects below the water.

Various levels of sonar, water resistance, materials, and screens are used to create a single GPS chartplotter. Due to these differences, it is important to know what you’re looking for and why you need one before making your selection.

Consider Where and How you will Use the Chartplotter

The size of your space and nature of your activity should have direct influences on the chartplotter that you select.

For example, a smaller console and deck space require a smaller chartplotter. Some of the chartplotters with larger displays can be quite bulky and harder to store, so keep this in mind when making your choice.

Additionally, pay attention to specifications. If you know you will use the chartplotter in saltwater, search for one that tolerates deeper saltwater depts and has more maps of saltwater areas for your convenience.

Compare Screen Qualities

When considering what the best marine GPS chartplotter is for you, some key qualities to look for in a screen are visibility, size, and brightness. Traditionally, the larger and brighter the screen the better the user experience will be. However, keep in mind that larger screens usually result in an increased price.

Also, consider if a touch screen is important to you or if you would prefer traditional keyboard buttons. Either choice is fine, but make sure to pay attention to what the model includes.

Decide what Features you Need

There are too many features to count on modern-day marine GPS chartplotters. To get a good idea of what is important to you, make sure you know what to look for.

Many chartplotters come with preloaded maps with thousands of lakes and areas. Ensure you are looking at the right type of GPS so that the maps can pertain to you and your habits.

Additionally, there are many types of sonar used. If you want continuous sonar, downward, side, etc., make sure the chartplotter you select has these and that you are prepared to pay a bit extra.

Finally, many modern-day chartplotters have Bluetooth and are mobile compatible! If this is important to you, consider selecting a chartplotter that will show your phone notifications, so you don’t have to risk getting it wet!

Construction and Durability

Since many marine GPS chartplotters are considered relatively expensive, you must get one that you feel confident will last. Luckily, as technology has advanced the companies have kept up with protective features to protect that technology.

A common feature to look for is the IPX rating, which is an indicator of water resistance. It is recommended by professionals to go with a rating of 5 or more to ensure water resistance that can handle large splashes. If you can go higher with an IPX-7 rating, that is even better.


It has been mentioned a few times and is no secret that price is a big factor in the purchase of the best marine GPS chartplotter. Let’s face it, they can be expensive.

It is important to view your chartplotter as an investment and not let price be the only factor you consider. Lower prices often mean fewer features, smaller screens, and possibly a shorter lifetime. So try to find a balance and remember that this is an investment.

When all else fails, try to remember the rule of thumb that a larger screen positively correlates with a higher price, and use this to guide your search.

Customer Satisfaction

At the end of the day, what matters most is your satisfaction with the product. It is a good idea to check for companies that have solid warranties and allow you to return or exchange the product if you don’t find what you want. A good warranty offers peace of mind and ensures you will end up with a nice product in your hands.


Here are some frequently asked questions about marine GPS chartplotters.

How deep can the best marine GPS chartplotter detect objects?

This answer depends on the model you purchase. Many have different depts that range from several hundred to a few thousand feet deep. Additionally, a single model can have different depth capabilities in freshwater versus saltwater.

Is my marine GPS chartplotter waterproof?

The way to tell how water-resistant your chartplotter is to take a look at the IPX score. We recommend a score of 5 or higher because this is resistant to splashes. A score of IPX-7 is the closest to waterproof and even then it is not recommended to intentionally submerge it.
