Fish Finder For Kayak Buying guide

When you want a fish finder for kayak, there is more to it than if it offers imaging sonar or HD display.

Most fish finders are unfortunately designed for powerboats. Designs for specific use in a kayak are, unfortunately, rare. Because of this, the best systems for a yak are smaller, portable designs.

The vast majority demand 12V power sources, and you will need to think about where you can place them.

Does the Fish Finder Fit?

The first step when buying a fish finder is where to mount it. Take your yak out on the water and paddle. Check if the fish finder would get in the way. Try various strokes and also stop your kayak and place your paddle across the gunnels. Make sure you wouldn’t hit your mount.

Can You Cast?

Start fishing and pay attention to how you’d cast in all conditions. Open water could be clear, yet under low-hanging vegetation, and you could find your fish finder has to be mounted low. Center console fitting makes the most sense unless you can get a positional mounting arm.

Battery and Cables

Once you know where to fit your fishing kayak fish finder, know where to run cables for the battery and transducer. Keeping them dry and also any fitting plates needs consideration, as do securing cables in place.


It may be a choice here, as some fish finders are portable yet may come with the risk of falling in the water. Permanent designs may offer a more secure offering yet will be exposed to the elements and can be damaged or even stolen during transportation.

Frequencies Used

Fish finders use sonar to locate fish. Cheaper models use dual frequencies, while the more current and better offerings use CHIRP or Compressed High-Intensity Radiated Pulse.

  • Low frequencies penetrate water and enable the fish finder a better chance to see deeper, although it may lack the fine detail needed to locate schooling fish.
  • High frequencies deliver more detail to pinpoint fish but are not very good at passing through water. For example, they can’t tell you much of the water bottom, especially if it is deep.

Dual frequencies enable your fish finder to carry out both readings simultaneously.

The angle of the transducer beam isn’t as vital as you may have been led to believe. Wider angles see fish suspended in a water column, yet narrower angles find fish near the bottom.


CHIRP technology uses longer pings across multiple frequencies. CHIRP systems deliver better accuracy than dual-frequency systems and pass data to the fish finder, thus improving performance.


Mounting a transducer correctly makes the difference to your fishing experience. You can find many ways to fit them.

  • Hull mounting: Used since the early days of kayak fishing. Cut a sponge to accept the transducer, then rest at the bottom of the hull in your kayak. It loses some signal, but not much.
  • Transom mounting: Here, you use a mount to attach an arm to your kayak. The transducer will be submerged in the water as it’s supposed to be. It can be damaged, however, should you hit rocks or stumps.
  • Scupper mounting: Kayaks come with scuppers to accept common transducers. Should your kayak do so, then check fish finders that will fit. Often you do find these come as added extras and more cost.

Maximum Depth

A fish finder should be able to read to a decent max depth.

Display Size

It may feel as if larger is better, yet not always. Larger screens can be easier to read, yet they easily get in the way as you fish.

Display Resolution

Small screens with good display resolution are easier to read than larger displays with not-so-good resolution.


GPS and maps or waypoints are great tools for anglers. Finding your way to good fishing spots or back home in strange waters can be a worthy addition.

A great way to use your fish finder is for map structure and cover, thus returning to where fish school and feed.


You want a fish finder that is good on batteries. Many don’t use regular batteries, but you will need a good rechargeable 12V before heading out on the water.

What’s the bottom line?

In testing, we put all the fish finders to work and quickly came up with the Garmin 010-01550-00 Striker 4 as the leader of the bunch.
