If you’re an avid kayak fisherman or even a novice, there are often some challenging days. You may only get a few bites or none at all. A kayak fish finder could be just what you need to ensure your kayak fishing remains a very relaxing activity. This article will review some of the best kayak fish finder options available on the market today for kayakers.


A fish finder is basically sonar. When you purchase a fish finder you typically receive a two-piece device – a transducer that acts as a transmitter of sonic waves. The second is the receiver, which is the display that converts that information into a picture.

You may find that some of the newer kayak fish finder devices only have the transducer. This is because you are able to connect it directly to your smartphone. A fish finder device not only tells where the fish are, but tell you how big they, if there is weed and debris below you, and the shape of the river’s bottom.



    The first thing to pay attention to is the transducer. This is the main and the most important part of the fish finder. You need to check the device’s cone angle. Smaller angle means that the beam of sound is more concentrated and the beam can penetrate further into the water. A wider cone offers wider field of vision but less depth. There are transducers that combine the two.


    The larger the display, the better the view, of course. Having a large display will give you more information, but will make the device clunker and risk dropping it into the water. The frequency of the transponder is also important. The higher the frequency of the sound the transponder is emitting, the more detailed the information gathered and the sound will penetrate deeper.


    Finally, you need to decide whether the device is portable or fixed. Many find that a portable kayak fish finder is the best option. This particularly true for those who may lease or rent a kayak from time to time. They can move it from one to another.

    Fixed fish finders do of course have great benefits. With a fixed version it allows you to skip the entire set up process and jump right on the water.

Obviously, the most important benefit of a fish finder is that you’ll be able to catch more fish, and catch bigger fish. But there’s more to it than that. Firstly, kayak fish finders are specifically built for the kayak. They are smaller in size and not cumbersome at all.

Secondly, a fish finder helps you survey the terrain underwater. It helps you detect debris and weed and avoid those places.

And finally, the device allows you to see the body of water’s bottom, which may help you figure out where are the fish hiding or what particular areas are rich with fish.
