Best Kayak Fish Finders Buying Guide

The type of fish finder that you buy will all depend on the style of fishing that you intend to do. If you are a deep-water fisher, then ideally you’ll want a finder that has downward-imaging software.

Transducers emit sonar waves downward, which then bounce back up to the boat, giving you a clear picture of what lies beneath.

Here are a few things that you’ll be looking for with your next fish finding device:

How Long Does The Battery Last?

This will all depend on what power supply your fish finder will take. Most of these portable units will only take AAA batteries, so your fish finder’s power will always be limited to just a few hours.

Is It Waterproof?

It should go without saying that you’ll need your fish finder to be utterly waterproof, as you will be surrounded by water the entire time.

Is It Down-Imaging Or Side-Imaging?

Down imaging will be when your fish finder will scan vertically down the side of your boat. This is to find the fish that are deeper in the water. More often than not, these will be larger fish.

The downside of having this vertical imaging is that you’ll only be able to see the fish directly underneath your boat and you will have to position your kayak accordingly.

If you choose to go with a side-imaging device, then you can expect to see a lot of the surrounding of your boat, as it will cover more space around the sides of your boat, rather than the down-imaging scanners.

However, these side-imaging scanners will generally cost a lot more than the down-imagers.

Does It Matter How Much Space You Have On Your Kayak?

The weight of the boat will certainly affect your fishing experience. However, you can get fish finders that float on the surface of the water, transmitting the location of the fish to your smartphone. This is a great feature that will save you a lot of space if you have loaded up your kayak with gear.

How Do You Mount Your Fish Finder?

Different fish finders are designed to be mounted to the side of your boat in different ways. There are some that are designed to be clipped into the mount that is built into your kayak, whereas others are designed to stick right to the bottom of your kayak.
