Thinks To Consider Before Buying

Reading reviews are indeed very useful when you want to buy the right fishing gear. Moreover, there are a few factors that may arise in your mind before you finally choose one.

So, here we will compile some of the crucial factors that you should consider when choosing a perfect fish finder for Kayaks. Let’s read them –


Always keep in mind that, when you go for Kayak fishing, you must choose lightweight and portable fishing gear. It’s also true for a fish finder. Fishing on a Kayak becomes more comfortable when you have a portable fish finder.

Because Kayaks contain very narrow space to keep all necessary fishing gears. So, a portable and easy to carry fish finder saves you from space hassle and make your fishing a lot easier.

Screen Size and Quality

Although a large screen fish finder is more user friendly than a small one. But for kayak fishing, large and heavyweight fish finders won’t be suitable.

But that doesn’t mean that you compromise with the quality. As Kayaks are tiny boats, you must choose a small fish finder that comes with a clear screen.

Generally from 2.2 to 4 inches screen size is enough for Kayak fishing. And we know, quality of the screen is measured by pixels. So, the more screen pixels you will choose, the more details you will get from the screen.

Waterproof Feature

A good fish finder must be water-resistant. Always choose a fish finder that has a waterproof feature.


If you tend to switch in different waters for fishing, you must look for a versatile fish finder. Choose a fish finder that works equally in freshwater, saltwater, or in shallow water.
