How to Choose Kayak Fish Finder

Use of kayak fish finders has become popular among anglers, many of whom have benefited from the nifty devices. The main challenge that arises has to do with choosing a good unit that offers lasting reliability. This section discusses important factors to consider when shopping for a kayak fish finder.

Screen resolution

The screen resolution is the most important factor to consider when it comes to choosing a kayak fish finder. Go for a screen with a larger resolution or the highest number of pixels you can afford. It will help you see clearer and more detailed images. Whatever you choose, make sure the screen resolution is not less than 240×160 pixels or higher than 640×640 pixels.

Transducer compatibility

In the past few years, kayak manufacturers have teamed up with fish finder brands to make scupper holes that match transducers. This allows for a stress-free installation and is something you will have to consider. For instance, Necky, Old Town, and Ocean Kayaks are owned by Johnson Outdoors. This is a brand that exclusively designs scupper holes for Hummingbird transducers. Hobie and Wilderness Systems kayaks come with Lowrance compatible mounting features.

Mounting space

The next thing you have to think about is the amount of mounting space available on your kayak. You will need space for the cables, small 12V battery, and charger, rods, tackle as well as a RAM or Scotty fish finder. The fish finder should have a large enough screen to view detail yet compact enough to not be in the way when casting or paddling.


This is calculated using units of wattage and the higher the number of watts, the more powerful it is. Higher power allows a unit to display clearer images more quickly. Sonar wave speed depends on a unit’s power. If the power is low, then the sonar speed will be slow and the displayed image blurry.

Cone angles

The cone angle determines the width of the beam transmitted through the water by the transducer. A wider cone angle allows the transducer to cover a wider area. However, it’s important to note that the image starts to diminish if the cone angle is too wide and waves too spread.
