How to Choose the Best Fish Finder for Kayaks

When you’re picking out the best fish finders for kayaks, there are certain factors to consider and a few different things to look out for before buying. Here’s our list of the most important things to check for when shopping for the best fishfinder for kayaks:

Sonar Reading

If you’re looking for the best fishfinder for kayaks, it’s essential that the model you choose is technically advanced. Look for a minimum sonar reading of 83/200 kHz to ensure that your chosen fish finder is accurate enough to pinpoint where the trout, bass, or bluegills are.

Another thing to consider is whether you need down-imaging or side-imaging, which depends largely on what you hope to catch. If you go for bass and bluegill, you’ll be casting on or just below the surface so side-imaging will be most useful for you.

However, if you’re into deep water angling, you need to look for down-imaging instead. The best fish finders offer both, but they might come with a premium price to match.


The transducer is the key to how well your device will work. It’s the transducer that actually creates the sonar waves and sends them out to pick out where the fish and other objects in the water are. The transducer picks up the echo and uses this to form an image of what’s happening below the surface.

You really want to look for a model that has a transducer included, as the best fish finders and the larger brands all do.

Compatible with your fishing kayak

You might be looking at the best fish finder – top brand and all – but if it’s not compatible with your kayak, it will serve no purpose at all. So one of the first things to check is whether you have space for the model you’re looking at.

Also, find out what battery power it takes and whether you’ll need to have a power supply on board, whether you’ll need to attach it to your kayak, float tube or pontoon boat (and how), plus how the transducer attaches to your fishing kayak. Once you’ve ticked these questions off and got suitable answers, you’ll know if you’re looking at a winner or not!


Display Size

The display size can vary vastly and you can often choose between black and white vs. color display, too. This is partly down to personal preference – black and white can show up more easily in bright sunlight, for example. However, a color screen can give much more detail than a black and white screen can.

The size of display you go for depends on how much space is available in your kayak. Some of the best brands offer a range of sizes, which is handy as it allows you to pick out your favored size.

Ease of Use

The best fish finders for kayak are simple and easy to use. You want a kayak fish finder to enhance your angling experiences, but you don’t want to waste too much time out on the water studying the manual!

Some models operate on a touchscreen, while others have a keyboard or buttons to control the device. We generally find that the best kayak fishfinders have buttons or a keyboard, as this is less finicky and fiddly when you’re out on the water.

GPS: Yes or No?

GPS or not? If you go kayaking further from home, you might benefit from having a combined GPS and kayak fishfinder, all in one. You can also combine two devices into one and save some space on your kayak – always a bonus!


How portable a fish finder can really vary: some are very easy to attach and remove from your kayak while remaining sturdy and durable for lots of use. However, some do require more intensive installation that cannot be removed easily without some planning and effort.

The advantage of having a fully portable version is that it’s not just limited to kayaking. You can switch things up and fish from different boats (for example, if you decide to team up with a buddy and spend a day out on the water together). You can even choose to cast out from the shore or from a pier with most models these days.

The most portable devices are small and lightweight, and many can link right up to your phone rather than having another device in your kayak.

Battery Power

Some models are rechargeable, while others take normal batteries that you can replace when needed. You’ll find that some fish finders will need to be connected to a large power supply source like a marine battery. This can take up valuable space on your kayak, but it does mean that your fish finder won’t run out of battery halfway through the day!

Weigh up how much space you have available and compare this with how long you need the battery to last on your angling trips. Some high range models do have a good, long-lasting battery, so if this is important for you, make this a priority when you’re shopping around.

Optional Extras

A good kayak fish finder will also offer extra features like the ability to measure the temperature and depth of the water and the speed you’re traveling at. You can also look out for functions like tracking the river bottom and more. This really varies, with basic fish finders for kayak offering fewer extras, while the best fish finders for kayaks will have a whole range of functions.
