Nevertheless, finding the right fish locator for your kayak is trickier than it seems. There are a few characteristics you should keep in mind:

Size: The most important consideration. A kayak isn’t a large vessel. Many of your options will be portable fish finders – with waterproof batteries built in – as a big one would be a bit out of place and inefficient on a kayak. You probably won’t want anything bigger than a 6” display, and you’ll want to make sure it’s relatively lightweight.

Transducer Compatibility: Certain kayak companies have partnered with companies to make sure that the transducers fit right into the scupper holes of the kayak. You may want to Google your kayak’s compatibility before you purchase your fish locating device.

GPS or Non-GPS: If you’re fishing on a big lake, you may want a GPS so that you can mark your favorite spots.

Now that we’ve got the basics nailed down, we’ll explore the nitty gritty details of five of the best fish finders for kayaks.

There Are Two Types of Best Fish Finders For Kayaks

1. Non-GPS Models

Garmin Echo 150 Dual-Beam Finder (1200 ft)

Display Size: 4”The Scoop: A no frills and budget-priced fish-finder down to its black and white display, the Garmin Echo 150 does exactly what you need without any of the bells and whistles that you don’t.

The Garmin Echo 150 can reliably scan for fish at depths up to 1200 feet in freshwater, and the 120 degree viewing angle gives you a wide berth for finding fish. It’s easily installed, and with its compact design, it’s not a hassle to use and won’t get in your way while you’re fishing.

A couple minor gripes – the plastic protective cover that is probably a necessity is sold separately. The instruction manual isn’t very helpful, so you have to figure everything out for yourself. And finally, this particular model wasn’t specifically designed with kayaks in mind (although it works great with kayaks), so it may require some adapting.

Lowrance Elite-4X Fishfinder

The Scoop: Boasting a color screen with a relatively small 4.3” display, the Lowrance Elite-4X is another great budget fish GPS model. The extra height of the screen is a bonus, as the screen’s vertical design is unique, useful, and easy-to-read. in terms of interface, this model is one of the best fish finders for kayaks.Also best suited for freshwater, the Elite-4X is relatively easy to install, only requiring plugging in two wires. However, some users say that its use isn’t very intuitive. Like the Echo 150, it’s user manual isn’t the best, and you’ll have to figure out how to do a lot of things by pushing buttons and experimenting.

2. GPS Models


Garmin EchoMAP 44dv

Display Size: 4.3”The Scoop: Though versions of this model have been discontinued due to a lawsuit with Lowrance, you can still get it off of the official Garmin website or other retailers.

Boasting a GPS and a 500 W HD-ID sonar, the EchoMAP 44dv is a big step up from the budget fish finders. The GPS feature is huge for tracking your locations, and the sonar’s timing is coordinated with your boat’s position. The Garmin DownVü sonar is arguably the clearest scanning sonar available right now.

The cables plug directly into the mount, so mounting and installing are a breeze. The screen is extremely clear, and the maps are, by all accounts, excellent.

Nevertheless, this uptick in features comes with a sizeable uptick in price, and only you can decide if it’s worth the money. The EchoMAP 44dv certainly has everything you could desire in a GPS finder, but it’s one of the pricier models on the market.

Humminbird 409470-1 HD GPS/Sonar Combo

Display Size: 7”The Scoop: Although the screen is a bit big, this Humminbird model made our list because of it’s fiercely loyal following among certain kayak fishers.

The Humminbird 409120-1 has a lot to live up to. Humminbird is known for their excellent customer service, and that’s good to know going in when you buy one of their models. The color picture is crystal clear, the sonar is informative, and the GPS is by all means relatively affected.

That said, this Humminbird model doesn’t necessarily offer anything that its peer models don’t. It sits among the best fish finders for kayaks out there, but doesn’t really stand out. It does the basics very well, but may not necessarily warrant paying the extra money. Moreover, it’s a bit big for a kayak, although the display is very easy to read in all conditions.

However, there is a cluster of kayak fisherman that ardently support this Humminbird model, and if you try it out, you may find that you’re one of them.

Raymarine Dragonfly 4PRO

Display Size: 4.3”The Scoop: The Raymarine Dragonfly 4PRO offers GPS technology while also keeping your wallet relatively full. The maps are solid, including many lakes, rivers, and coasts, and the sonar and LED display to make this model one of the best on the market.

One cool, social, millennial-type feature – with Raymarine’s Wi-Fish app, you can save and share your days catch with friends on social media.

Moreover, at a sleek 4.3”, the display is perfect for a kayak. One user even claims to catch 3-10 largemouth bass in a relatively dry river thanks to the Dragonfly 4PRO.

The Dragonfly 4PRO’s Achilles heel is likely Raymarine’s tech support, which has been roundly criticized by a few users. Perhaps more importantly, a limited number of users have reported huge navigational issues in slightly more remote areas.

As such, the Dragonfly 4PRO is a cut below the Garmin EchoMap 44dv; however, that’s to be expected with the drop in price, and the Dragonfly 4PRO is a good middle ground if you want a fish locator with a GPS but don’t want to break the bank.


As with most outdoor gear, you usually get what you pay for. If you are a casual kayak fisherman who is mainly fishing in the shallow fresh water, you may want to opt for less-expensive models. If, however, you find yourself out on the ocean casting for a bigger catch, the

If, however, you find yourself out on the ocean casting for a bigger catch, the Garmin EchoMap or the Humminbird may be your choice. When you’re looking for the best fish finders for kayaks, always weigh your needs against your budget.
