Benefits of Fish Finders for Kayaks

7 best fish finder for kayak

First, let’s discuss why you should buy a fish finder. It is an effective tool that comes in handy when you are fishing. It allows you to see the fish and know where it is.

A fish finder works using Sonar technology. Sonar stands for Sound Navigation and Ranging. This is not just a concept from your high school physics textbook. It serves as a great tool for finding fish.

It sends sound waves of different frequencies that echo back and help you locate the fish underwater. You will be able to see a graphic representation of everything that is underneath your boat.

The fishing finder does more than find fish for you. You can see all the weeds, debris, rocks, and sand under the boat. You can also view the precise depth on the screen.

In short, the best fish finder can be a great gear for kayaking. If you are a big guy, you may want to look at our hand-picked kayaks for you or our list with the 10 best fishing kayaks under $1000.

Buying Guide

What Features should you Consider when Choosing the Best Fish Finder for Kayak?

You will find many brands of fish finders that boast different specs and numbers. It is easy to get confused with the sheer amount of information. You may even end up buying the wrong fish finder.

The following is a list of the features you must remember before buying the best fish finder. The correct fish finder will surprise you with its performance. This is a great way to catch a lot of fish.

Portable or Permanent Fish Finder

You will find both portable and permanent fish finders on the market.

The permanent fish finders can be fixed on large boats. For a kayak, a portable fish finder can be a great option. A portable fish finder will let you enjoy many types of fishing.

Moreover, it is the best option for rental boats. It is lightweight, so you can easily move it on the boat.

Screen Size

Screen size is another important feature when choosing the best fish finder for the kayak.

A rule of thumb is to buy the biggest screen size that aligns with your budget. With a bigger screen, you can see more information at one time. You should choose a smaller screen because kayaks are small and low to the water.

Screen Quality

Also, keep an eye on the quality of the screen. The pixels of the screen determine its quality.

A pixel can be thought of as a single dot on the screen. So, the more pixels you have, your screen will be more detailed.

Ensure you are not sacrificing quality in getting a larger screen size. When choosing a cheaper fish finder, look for one with a good screen resolution.

Grayscale versus Colored Displays

This is another essential feature to consider when choosing the best fish finder for a kayak.

Colored displays have taken over black-and-white displays. However, with a fish finder, a grayscale display works just as well. Furthermore, a black-and-white display is cheaper than a colored display.

While a color display looks better, it provides the same functionality as a black-and-white display.

Glare from the sun

When purchasing the best fish finder, it is essential to keep the real conditions when fishing. The glare from the sun makes it hard to read the fish finder screen.

You can use some LCD films that can combat glare. You can even invest in glare-resistant screens.


GPS, or Global Positioning System, is the most important feature when you go out kayak fishing. A GPS device can help trace your route and save your favorite fishing spots. Moreover, GPS is more essential for kayak fishing than for shoreline fishing.


A transducer is a very essential part of the fish finder.

Transducers serve as the senders and receivers for the sonar waves. The sonar waves that bounce off different objects are detected by the transducer. The signals from the transducer are then processed. The output of these signals is a graphical representation on your fish finder’s screen.


If you have the budget, you should always consider high-watt fish finders. These will help in giving quicker readings. A low-power fish finder sends waves very slowly and isn’t as reliable for deep-water fishing.

However, if you intend to fish only in shallow water, you will do well with a low-power fish finder as well.

Water Resistance

A good fish finder should be water-proof. Otherwise, the water splashes will ruin it. Therefore, you need to make sure that the brand you purchase offers a good level of water resistance.

Number of Frequencies

Most transducers work well with dual frequencies. A higher frequency will give a clear and detailed picture of your display screen. The higher the transducer frequency, the more sonar pulses it will send out.

For example, some fish finders can get up to 400,000 Hz while using different frequencies.


Often, people think that price is the most important aspect of fish finders. Choosing the fish finder by the price alone is a big mistake.

A fish finder is an essential tool that fishers in the past could only dream of having. So, you must ensure you don’t compromise on essential features for a cheap price.

The display specs, GPS, sonar, and wattage are vital factors you must consider before making the final decision. Otherwise, you will regret buying the wrong fish finder.

Final Thoughts:

Most kayakers do not know what specs and features to look for when purchasing a fish finder. We hope this article will help you find the best fish finders for a kayak.
