Kayak Fish Finders Buying Guide

If you’re just about to start your fishing journey, the chances are that you do not know how to choose the best kayak fish finder. It’s not that easy since a simple search will throw countless products your way. Therefore, no matter if you want the best fish finder under 300 or the best fish finder under 200 – you have to know what to look for while shopping. As such, here are a few things to keep in mind when you want a fish finder for kayak:


While it should not necessarily be the decisive factor when you’re looking for a new fish finder, the brand may be something to take into consideration. Some brands have been doing this for a long time, meaning they have the experience needed to create the most amazing products.

So, if this aspect matters to you, then check out products from brands like Garmin, Humminbird or Lowrance, although an Eagle fish finder may be just as amazing. Buying from a reputable company will not only give you peace of mind as you know you purchased something of high-quality, but it will also give you a good warranty.

Installation Process

The last thing you want while you’re in a kayak ready to start your fishing day is having to spend too much installing your fish finder. Not only that you want to get to action already, but it can also get annoying when you were looking forward to a nice day. Therefore, you need to settle for a fish finder that is easy to install. There are plenty of them, even from big brands, that make the installation process a piece of cake. By purchasing one of these, you will be able to focus on the fishing aspect instead of having your day ruined by anger.


How far away from home or shore do you intend to travel when fishing? You need to ask yourself this question before you invest in a fish finder. If you plan on going far away from the shore, then getting the best fish finder GPS combo may be the best option. Something that comes with GPS options will be more useful than you think, as it will let you know where you are when you need to fish.

However, these units tend to be a little pricier than your average fish finders that have no GPS circuit.

Water Resistance

You want your fish finder to last, don’t you? If that’s the case, look for waterproof devices. You’re on a kayak, after all, so there’s always a high chance of your device being splashed with water. If you don’t look for something resistant to water, you risk ruining it and you will have to spend money on a new one.


Price is an essential factor to consider as well because you may not be able to afford the high-priced units from popular brands, in which case you may need a cheaper one. At the same time, it would be a big mistake to only consider the price when you buy a fish finder.

The best way to make a decision is to also check what the device offers for the price. Does it have everything that you need? Furthermore, are the reviews good? Were people pleased with it, or did they have issues with it? When you’re about to settle for a cheaper product, don’t hesitate to ask yourself all these questions.

Sun Glare

Isn’t it annoying when the sun makes it hard for you to see what’s on a screen? Some fish finders have this issue, which would make it hard for you to find out where fish is located. For this reason, you need to invest in a fish finder with a glare-resistant screen or use an LCD film. These will help you read the screen even when the glare from the sun is strong.

Screen Size

Screen size matters because larger screens will make it easier for you to read the details on them. However, since you’re on a kayak, you have limited space, which means you might want to settle for a smaller screen instead.


When shopping, you are going to find both portable and permanent fish finders. Permanent ones can be a great option when you want something to fix on a boat. As such, since you’ll be on a kayak, you can settle for a permanent one.

At the same time, this doesn’t change the fact that portable ones are easier to carry with you. They are lightweight for the most part. If you want, you can even settle for a castable fish finder.


We’re talking about finding a real fish finder here, not the Terraria fish finder, so depth needs to be considered too. When fishing, it’s hard to know how deep fish are swimming, so if you want to find that out, getting a device that can scan the area at larger depths is ideal.

You might want to get a deeper fish finder that shows you how deep the water below your kayak is and can also locate fish that swim deeper. It’s a great feature to have.

Frequently Asked Questions

Q: What is a castable fish finder?

Castable fish finders are devices that are attached to a cast line. In order to function, they make use of sonar technology and map the body of water to be able to locate fish. In essence, they are great at showing you the graphic representation of what’s under your kayak.

Q: What is the transducer?

The transducer is an essential part of a fish finder that gives your device details about the scenery below your kayak. It uses sonar technology and thus sends out signals or waves, which then bounce back to give you details. It’s a great system if you want to stay away from hazards and find the best fishing spots.

Q: What is the ideal depth for a kayak fish finder?

The best depth scanning capacity of your fish finder should be considered based on where you’re fishing. Some devices can deal with a 750 feet range, while others can scan at 500 feet, 250 feet, and so on. It’s essential to look at your favorite fishing spots and pick a depth based on that.


If you want to make sure you have the best fishing experience, then it’s essential to get the best fish finder. After all, you don’t want to waste your time in spots that barely have any fish. With one of these amazing devices, you’ll make your family and friends proud of your skills.
