How would you feel if you get to catch that fish you always dream of almost every time? Well, if you think this is not achievable, I am here to disappoint you because technology has been developed to make this achievable.

Having the Best fish finders for kayaks will motivate you more as you continue to get the best catch of your life.

A fish finder will help you get the best fish in the water without much hassles and stress. But wait a minute, before you jump to purchase a fish finder for kayak, there are some things you will have to consider especially if you are just new to this technology.

You wouldn’t want to attach a fish finder of about 10 inches screen to a small boat or kayak, it’s certainly going to get in the way and cause lots of distractions.

What to look out for when buying a fish finder for kayak

A fish finder basically have three parts/components: the screen, the transducer and the power source.

It is very necessary to take these into consideration so you would be satisfied with your purchase on arrival of the device.

Screen size

The screen size determines how large the fish finder would be. If you use a small kayak, then it would be weird to attach a big fish finder to it, it’s going to look too clunky. Normally, most kayak aren’t wide, so it’s wise to settle for smaller fish finder, anything from 5-6 inches display size will just be great. If you are going to be mounting the fish finder on a ram mount, then anything larger than 6 inches will be too heavy. The idea is to make the mount ridged and firm as much as possible. In summary, we recommend you shouldn’t go above the 6’’ mark for screen consideration.

The transducer

This is one of the most important component of a kayak fish finder. It’s responsible for sending signals into the water and receiving signals and transfer them to a visual from on the screen. Most of the transducer will come with a transom mount transducers out of the box and you won’t encounter any challenges installing it. You will also want to go for ones with wider cone angle which covers more area view. If you are using either in-hull or thru-hull transducers, you should consider plastic housing for fiberglass and metal hulls while Stainless steel housings will be great for steel hulls aluminium hulls.

Power Source

You will need to find a power source to supply power to both the traducer and the display. This is where you will have to come in. you can get a marine battery for this purpose. For safety purpose, it will be wise to wrap the battery in a waterproof box. If you feel this will be challenging for you, then you can opt in for portable fish finder that comes with built-in waterproof battery pack – this will ease the job of doing all those DIY.

Screen Resolution

The higher the resolution, the better. Resolution is rated in pixels and a high resolution implies a better pictorial representation of the underwater world. So if you don’t want to be discouraged by the display on the screen, it is better not to settle for resolution below 240 X 160 pixels. Once you can get the best resolution that will display clear view, you wouldn’t bother about the size of the display.

Cone angle

If you are lucky to get a wider cone angle, you will be able to see a wider view. This is an advantage. But the challenge with this is that as the cone angle gets widen, the focus and sensitivity reduces with depth. There are different ranges of options from 9-60 degrees, but to be on a better side, a cone angle of about 20 degrees will be great, however, going wider isn’t a bad idea.


The frequency of the transducer is something important to consider when buying a fish finder. They can either be single, dual or multiple frequencies. Some few dual frequencies transducers would normally come with 20 and 60 degrees cone. Some frequencies you could get are 50, 83, 192 and 200 kHz. Basically, for shallow waters, it is better to get higher frequencies like 192 and 200 kHz. The lower frequencies will work better for deep waters.
