Best Fish Finders for Kayaks 2018 – The Ultimate Guide & Reviews

Fish finders need to adapt to your boat, kayak or any other vessel just as much as the person on it. And finding one for a kayak is probably one of the most daunting experiences due to the size and build of the kayak itself. But we are on a mission to send you home with one of the best fish finder for kayaks by the end of our article, and we aim to deliver.

Read through our article and find out how to easily pick the best fish finders for kayaks using a few simple points. We have also put together a list of some of the most assorted kayaks fish finders that will make your search so much easier. Enough yapping, let’s get started with the basics!


A fish finder

It is very unlikely that an avid fisherman doesn’t know about a fish finder, but for anyone who’s new to it, we will explain happily. A fish finder is basically an instrument or device that uses sound energy or waves (sonar) to find out about certain specifications like water depth, water temperature, bottom contour, underwater bodies ( reefs, discarded tires, rocks, logs, etc) and of course, the approximate locations and whereabouts of fishes.

The transducer transmits or emits frequencies into the water which reach into it and bounce back against anything that it touches. Next, the receiver simplifies these reciprocal frequencies and produces information based on this on its screen. One can easily guess that the fish finder is used for a lot more than finding fishes when they look at what else they are capable of.

Won’t any fish finder work on your kayak?

This is important so pay attention.

Yes, any fish finder will work on your fishing kayak. In fact, it will just as well work on any other water vessel as long as it floats. But at the end of the day, it all boils down to comfort and smart-thinking due to prolong hours of use. Furthermore, you have to understand that kayaks and boats are not the same thing. Here’s the problem with kayaks:

  • They are thinner than boats so you have less space to work with
  • Are less spacious so storage is a problem
  • Offers less mounting facilities so transducer is at risk

The circumstances in a boat or most other vessels are however very, if not entirely, different. So, keep these points in mind since you have to pick fish finders that complement and adapt to your kayak and its body without compromising on the quality of your experience. There are a few points to consider when you are on look for some of the fish finders for kayak. We will them explore now.

Things to Look For in the Fish Finders For Kayaks

1. Compact

First of all, try and look for in a fish finder for a kayak lies in its size. Look for finders that are small, compact and portable. They should be just big enough for you to comfortably hold it; no more! As a rule of thumb, you should be able to easily travel or carry around the device with you at all times. In addition to this, smaller fish finders also mean you can easily mount, install or store it in your kayak where space is so extremely limited.

If possible, avoid buying fish finders that come with receivers (or display monitors) that are too large. They should be comfortable to look at but not so large that it costs you its very safety at some point.

2. Mounting

Because kayaks are extra low and extra close to the water surface, you have to make sure that your receiver sits securely, snuggly and super safely on top of the kayak, and in front of you. One loose screw and there goes your device for good!

Conveniently, chances are that your finder will come with all the necessary accessories to mount or install it. All the finders on our list have been chosen wisely keeping this in mind, at least. Anyway, most receivers come with brackets so that you can set or screw them into a flat surface while others may come with adhesive or suction pads and so on. However, we recommend getting finder that come with receiver which can be attached to a neck strap. This way, it’s always close to you, you can look at it any second and there’s lesser risk of it falling off.

3. Waterproof

You are in closer contact with water on a kayak than you would be on a boat. Needless to say, it is common sense that you get a fish finder that is waterproof.

Now, transducers are made to be dinked or floating in water so they are, but receivers are often skimped on. In other words, receivers are not always made waterproof. Now, this isn’t entirely a deal-breaker since it is made to stay on the surface away from the water, but you never know when it might get splashed on sprayed with water!

4. Wireless fish finders

First of all, let us just start off by saying that we are in no way saying that wired transducers are inferior or any less than wireless ones. In fact, we have mentioned a few on our list of the best fish finders for kayak. However, there are some perks to using wireless finder over wired ones on a kayak.

First, wires are trouble. These things may look thin and skinny but they chomp down a lot of your kayak’s premium space. And to add to that, let’s not forget how annoying it can get to detangle and unravel a messed up and tangled wires line. No one needs this drama in the middle of the water, seriously.

Second, wireless fish finders mean smaller and lighter transducers (sensors). These will often come to you looking like a ball, usually the size of a tennis ball, and they float on water.

Third, these transducers are easy to carry, easy to cast and so much easier to retrieve.

5. Wired fish finder

Like we said, we have no hard feeling against wired transducers since they are just as effective. But if you must get them for you kayak, try and follow a few rules.

First, do not get finders that come with a gigantic transducer. These are heavier so need to be more securely mounted; and are more difficult to detach too. Instead, go for one that come with smaller and more petite transducers. Look through our list; there are plenty.
