Best Kayak Fish Finder Buying Guide

As long as a fishing device is concerned, there are always some factors that determine which product you need, based on the requirements and budget. The same goes for choosing a fish finder for a fishing kayak. Therefore, here we have added a well researched comprehensive buying guideline containing all-important buying factors-

Frequency of the Fish Finder

There are two factors related to signal frequency of a fish finder- The Cone Angle and The Frequency. Cone angle is of mainly two types- 60 and 20 degrees. On the other hand, most transducers come up with fishfinders of 50, 83, 192 or 200 kHz frequency. Also, the can generate Either Dual or Single or Multiple signals. If you think about the combination, then most of the dual frequency fish finders are of 20 or 60-degree cone angle. And as an expert, I prefer to purchase a dual frequency fish finder.

Power Source and Consumption

Fish finders are all remote to use. Therefore, your fish finder will run on batteries when functioning. So, eventually, you have to ensure that it has maximum power backup inside to serve you longer.

Powers in fish finders are usually measured as Wattage. The greater the wattage, the faster it works and get you information from deep of the water. Also, if you are like to fish in shallower water, I suggest not to worry that much on the Wattage.

Display Resolution

You will be analyzing whatever data the fish finder provides on the screen of it. So, the display that comes with the device needs to be clear, nice and colorful.

The resolution of the display is measured in pixels. For a smart fishing experience, you would like to have a resolution of a minimum of 240(v) x 160(h) pixels. Obviously, more resolution is better.
