Best GPS for Kayaks: Waterproof Navigation, Fishfinders and Maps


One of the best parts about owning a kayak is getting to explore places you never thought possible. One of the worst parts — if you don’t own a good kayak navigation GPS system — is not knowing how to get back out.

In the days of LTE and 4G data speeds, it can be tempting to think a smartphone is all you need for kayak navigation. Out in the wilderness, though, there aren’t usually an abundance of cellphone towers, and it’s not worth taking the chance.

The best kayak GPS devices offer a lot more to the intrepid paddler than a cellphone ever could, anyway. With offline maps, waterproof touchscreens and world-class (literally) navigation — not to mention kayak GPS fishfinders, water maps and longer battery life — these devices are built with adventuring in mind.

The Best GPS for Kayaks – American Paddler’s Reviews

Garmin is generally recognized as the leader in GPS technology, so most of our recommendations reflect this. Our kayak GPS reviews are organized in four categories: fishfinder GPS combos, budget kayak GPS units, midline units and high-end devices.

If you’re planning to embark on longer kayaking adventures, you’re gonna need to do better than a rubber ducky and a compass. A good kayak GPS device allows you to chart your course, plot interesting points and even get weather alerts.

How to Choose the Best Kayak GPS

Most kayak GPS units have standard features such as basemaps, the ability to set waypoints and save favorite locations. However, there are some key differences to watch out for.

Made for Water?

All of the kayak GPS reviews on our list are waterproof to IPX7 specifications — which means they’re resistant to splashes, rain or even immersion up to 1 meter for 30 minutes. However, some offer extra marine-specific features, such as:

  • Built-in fishfinders
  • Marine cartography maps including shorelines, coastal charts, depths, harbors and marinas (or the ability add such maps)
  • The ability to float
  • Mountable backings for use with kayak gear tracks

Battery life can be important, too, when out on the water, and a backlit, sunlight-readable display can help when shade or cloud cover can’t be found. A few units even offer weather updates.

Navigation speed and accuracy

GLONASS and GPS: Whenever possible, look for a kayak GPS device that features GLONASS support in addition to a standard high-sensitivity GPS receiver. Standard U.S.-based GPS technology relies on 31 satellites to track location. However, some GPS devices can be paired with GLONASS, a Russian-based satellite system that tracks 24 additional satellites — greatly increasing your device’s speed and accuracy.

HotFix satellite prediction: Another great feature on some GPS units is HotFix, a technology that greatly speeds up loading times by allowing your device to “predict” the location of satellites based on data collected over a period of days.

Compass and Barometer: Some of the best kayak GPS devices also come with built-in electronic compasses and barometric altimeters, which can detect both changes in the weather as well as your elevation. Both are handy kayak navigation tools if you’re paddling in mountainous or remote areas.

Mapping and Tracking

best GPS for kayaks
The best GPS for kayaks depends on what’s important to you. Some units are better at tracking, while others have bigger screens or more versatile mapping options.

Course charting and waypoints: If you’ll be using your GPS as a sea kayak navigation aid — or paddling any kind of long distance — the ability to chart your course and plot waypoints is critical. Not only does this allow you to find your way back, but your GPS can also help you track your speed so you can predict arrival times.

Adding maps: Most units come with a built-in basemap (usually covering North America or worldwide), but depending on your needs, it may be worth it to invest in additional maps. Some maps that are commonly available include topographical maps, coastal charts, city (road) maps, hunting maps and satellite images. It’s important to make sure your GPS can support additional maps, either via an SD card or the unit’s memory itself. This is especially important if you’ll be using your GPS for multiple purposes.

Additional features

If you’re looking for more than just simple kayak navigation, some GPS devices come with additional bells and whistles, such as:

  • Paperless geocaching with automatic downloads
  • Wireless Internet and Bluetooth connectivity for emails, apps and text alerts
  • Built-in digital cameras to allow you to geotag locations with images

If you’ll be mounting your GPS on your kayak, pay attention to screen size, too. Larger screens will be more easily readable from the cockpit.

A quality GPS fishfinder at a very good price, Humminbird’s Helix 5 offers a boatload of technology for serious kayak anglers. Dual-beam sonar and down-imaging technology let you scan a wide area to see where the fish are, or scan right below your boat for high accuracy and bottom visibility.

One of the best features for kayak anglers is this GPS fishfinder’s brightly lit, 5-inch HD display. Backlit for excellent visibility in both sunlight and at dusk, it also features Humminbird’s SwitchFire monitor, which allows anglers to control how the unit displays sonar images — either in clean mode (showing just the fish) or max mode, which displays a full sonar picture. Despite the large display, the unit still includes analog buttons for easy operation.

The precision internal GPS lets you chart courses and fishing spots — which is made easier thanks to built-in watermaps of U.S. rivers, lakes and coastlines. For venturing into uncharted waters, there’s Humminbird’s AutoChart Live feature, which makes a map as you go. And Humminbird’s SmartStrike technology helps you find where — and what kind — of fish are out there.

For the price, this is without a doubt one of the best kayak GPS fishfinder combinations out there.
