How to Choose the Right Kayak Fish Finder

To find the best kayak fish finder, there are a number of things you should consider. These include:


You can tune into the depths under the surface by using the frequency of the fish finder. The frequency operates in single, dual or multiple frequencies. These different frequencies have their benefits.

Fish finders come with frequencies of 50, 83, 192 and 200 kHz. Consider where you will be fishing to determine the best kayak fish finder to buy. If you will be fishing in shallow waters, go for fish locators with higher frequencies. For deep depth water fishing, you need locators with lower frequencies.

A good rule of thumb is to map out the area you will be fishing most of the time to get an idea of how deep the water is. From there, you can know whether to get a lower frequency or higher frequency fish finder.

#Cone Angle

Another important consideration when looking for the best kayak fish finder is the cone angle. These part comes in different degrees, from 9 to 60 degrees.

If you usually fish in all water depths, go for 20 degree cones. You can change the cones from depth to depth.

Keep in mind that the higher the cone degree, the larger the area it can cover. While this is ideal when fishing in large water bodies, the cone’s sensitivity reduces at a higher angle. Therefore, before choosing a cone angle, consider where you will be fishing most.


One of the most important parts of a fish finder is the transducer. This part produces sonar waves into the water. The sonar signals bounce off the water and come back to the transducer.

There are different types of transducers in the market with varying performances. For kayak fishing, you need a transducer that is easy to install. If you have a fiberglass kayak, the best fish finder to go for would be a bronze one.

Get a transducer that will perfectly fit in your kayak and provide correct readings.

#Screen Resolution

Avoid buying a fish finder that has a display that is difficult to read. After all, your eyes will always be on it when fishing.

The fish finder display screen resolution is measured in pixels. The more the pixels, the better the display quality. The size of the screen and its resolution should help you determine whether or not to choose a particular fish finder.

The best fish finders for kayak fishing have a minimum resolution of 640 x 640 pixels. If you are on a small budget, the least resolution your fish locator should have is 240 x 160 pixels.

The pixel resolution makes a huge difference when in the water and can differentiate between a fish and a rock. Look for a fish finder that will work well when you are in the water. The device should be easy to read.


Consider the device’s wattage. If your kayak fish finder has low power wattage, it can be difficult to read the information output. Moreover, when you are out in a kayak and have no idea of the water depths, a low-wattage fish finder can be slow.

You can get away with a low wattage fish finder when you are in shallow waters. When in deep water, the device will not be any good.

Choose a high wattage fish locator that will run faster to keep up with the water.
