How to Choose Fish Finders for Kayaks

How deep do you want to fish?

In order to find the best fish finder for your specific purposes, you’ll want to first consider how deep you’re planning on fishing in the water. Fish finders are really only meant for those that want to fish in waters more than eight feet deep, so any shallower waters can be fished in using sight skills. More specifically, you’ll want to think about whether you’re planning on engaging in structure fishing or shallow water fishing.

Structure fishing

Structure fishing ultimately refers to fishing in deeper waters. That being said, structure fishing is the best for using fish finders in. These models work best in structure fishing because they can display the overall structure of the water beneath the kayak’s surface, and they can display the temperatures of the water at certain depths.

Shallow fishing

Opposite from structure fishing, shallow fishing refers to the type of fishing methods used in shallower waters. Usually, they encompass bodies of water that measure less than eight feet deep. That being said, you may not need a fish finder device, and you may even be able to more accurately catch fish using sightseeing skills.

Features included

There are a few features that you can look at in order to help distinguish the higher-quality fish finders from the lower-quality ones. Most makes will have the ability to display at least the depth of the after as well as the structure of the bottom ground. But you’ll see as you’re browsing that the different features offered by more expensive models can make your fishing experiences more convenient.

For instance, most expensive fish finders will have CHIRP sonar technology, which is essentially the ability to better identify fish throughout the water. With CHIRP technology, fish finders can more accurately notify you of the types of fish below the surface as well as their distance from one another. Additionally, some of the higher-quality and better models will come with GPS map functions. You’ll usually want a fish finder that has built in GPS technology because you can more easily track your routes and personalize your kayak fishing experiences and mark favorite fishing spots. Also, GPS technology can give you more accurate readings of the slopes and edges throughout the underwater structure.

More expensive and higher-quality fish finders will also come with the ability to display easier-to-read screens, especially when reading them in direct sunlight. Overall, some of the more expensive models will offer you better and more accurate readings of the underwater strata, water flows and temperatures as well as more detailed readings of fish in the underwater world below your kayak.

Do you want it mounted to the kayak or handheld?

You should also consider whether you’ll want to purchase a fish finder that can be mounted to the kayak or a portable fish finder that you can hold while you’re kayak fishing. You should really only consider handheld ones if you’re known to use other people’s kayaks or if you don’t use the same kayak often since you can more easily transport the whole fish finding system to a different boat when needed.

You’ll ultimately benefit more from using mounted fish finders, since they can be mounted in any location that benefits you the most and you don’t have to worry about holding the device to read the results it displays.

The Transducer

The transducer is the main device on fish finders that’s responsible for providing the readings of the underwater world. A higher-quality transducer will deliver more accurate readings, since they can better convert the electrical pulses into sound waves under the water. It functions by sending out sound waves into the water and using the returned waves to determine the waterscape of the underwater world. It’s a separate unit from the readable fish finder device, so you should consider if a certain fish finder is compatible with your kayak and where it’s attached.

Is it compatible with your kayak?

Different transducers require certain conditions that you’ll need to accommodate for if you want accurate readings of the underwater world. Ultimately, they require different mounting and visibility methods, so it’s important that you adhere to them for your specific kayak. Most Fishing kayaks should be compatible with side-mounted fish finders because the transducer can simply be installed on the tracks, but you’ll have to ensure that your kayak has tracks.

Attaching a transducer

Transducers have different mounting requirements, so you’ll want to read the instructions thoroughly to determine whether you have to attach the transducer in a certain location. More specifically, transducers can either be installed onto the tracks on the side of the kayak or through the inside of the hull. Either way, you should make sure that you’re capable of attaching the transducer according to the assembly guide that it comes with.


You’ll want to consider what type of software the fish finder operates on, since this will ultimately determine the level of usability that the device is compatible with. Many companies release software updates frequently that can help to improve the user’s experience, so it’s important that you learn how to access and modify the settings on the installed software of your fish finder device.

Power Source

The power source refers to what powers the fish finder and where you’ll need to install it. Most finders can function off of at most a 12-volt power supply, but you may be able to use a battery with less power depending on how often you’re planning on using the device.


Where can you install it?

Where you install the fish finder device ultimately depends on your personal preference as well as the requirements of the device. Some fish finders require a certain mounting location, while others give you the option to choose where you mount it. Regardless, you should read the instructions that come with your fish finder and accommodate for the location that it requires. Most even come with the mounting gear to install the device, so you may want to consider purchasing a device that includes this option.

Which is the easiest fish finder to install?

The ultimate easiest fish finder to install is the Deeper PRO Smart Portable Fish Finder, since it features a castable design that’s compatible with your smartphone. Aside from a castable design, you can also benefit from the Garmin Striker 4 Sonar Fishfinder that has an easy-to-install transform/trolling motor mounting kit.

Final Thoughts

Overall, the best fish finders can make your kayak fishing experience much easier. When using the right inns of kayak fish finder, you can more easily find out what the structure of the underwater world looks like and, in turn, you’ll be able to find the best places to cast and effectively catch the types of fish that you’re looking for.
