What Is A Kayak Fish Finder?

Best Kayak Fish Finders

Simply put, a kayak fish finder is one that you can use in a kayak. Technically you could mount the biggest fish finder out there and use it in a fishing kayak.

However, that is not going to be very practical. There are both weight and room restrictions so while possible, it may not be to your benefit.

Ensure that your fish finder comes with a transducer as well. Sometimes they come separate and this just adds another expense. Also, wi-fi is a plus, as having a backlight and a micro-sd card slot.

An LCD screen will also ensure clarity, along with a color screen. A color display is not needed but it helps locate spots more efficiently. 

Instead, you’ll be using something much smaller. Most kayaking fish finders will be in the 3-7 inch range. These are small enough that it won’t take up too much space, and it also won’t be as heavy as some of the larger counterparts.

A quality fish finder will have sonar technology and could be mounted near the trolling motor with the transducer being able to go through a scupper hole.

Benefits Of Kayak Fish Finder

Using a fish finder instead of your naked eye to locate structure and fish is going to be very beneficial to you as an angler. A whole new world is going to open up and your ability to locate and catch fish is going to increase significantly. 

Even if you are not able to catch the fish you find, you’ll still be locating the areas where they hang out and you can continue to try new lures each time in order to get them figured out. No longer are fish finders only for anglers on large boats.

Considerations Before Purchasing A Kayak Fish Finder

Below, we’re going to go over a few different features and considerations you should be on the lookout for when purchasing a fish finder. Check them out and see which of these are going to work best for you and your style of fishing.


The size of the fish finder will all depend on what you need as well as the size of your kayak. Larger seats on tops that are more stable and can hold more weight will be able to handle a larger fish finder.

Smaller kayaks are going to be better off with smaller options that have greater portability. The smaller options potentially have lower khz, and pixels. Making the screens not as clear. Look for these to around four inches in size.

GPS Integration

Having a GPS combo in your fish finder is a great added feature. It allows you to see in both shallow water and deep water, you will be fishing and can allow for easier decisions while out fishing as to where to go.

Also, many fish finders with GPS also allow you to add waypoints. This is great for when you find a great spot where fish are located and want to mark it so you can always come back.

Also, having GPS will allow you to easily find and get back to the boat ramp after a long day of fishing. Which may not be that big of a deal on your local lake.

However, on new water, you could find yourself tired at the end of the day, and having GPS could mean the difference between getting to your truck at sunset or getting lost.

Mounting Type

If you have a larger kayak that can support a bracket and mount for your fish finder then you should utilize it. Ensuring that your fish finder is one spot and securely allows you to have peace of mind that it will be falling overboard and getting lost forever. Something that can happen if you have a handheld fish finder that is not secured.

It might be difficult to mount it on a kayak. However, all you need to do is locate the transom and mount it there. From here you can install android or IOS and BlueTooth capable fish finders that come with dual-frequency and high functionality. Making it easier for kayakers to find fishing spots that are castable. 

Portable or handheld fish finders are great. Especially for smaller kayaks. However, as we mentioned above it does open up the possibility of dropping it overboard.

Since you will be holding it and moving it around the kayak then you could easily drop it into the water by mistake. So, keep that in mind when purchasing your fishfinder.


You may think that all fish finders are waterproof. However, you would be mistaken. Be very careful if you do wind up purchasing something that is not waterproof. A big rain, or drenching it from holding a fish over it could lead to your new fish finders going haywire and not working.
