Best Kayak Fish Finder – Top 3 Guide

Kayak fishing is exploding in popularity. More and more people are finally migrating from the shores of their favorite pond and lake and venturing into the best spots that can’t be reached by foot, or boat! Kayak fishing gives anglers an edge over everyone else as their small profiles on the water get them in tighter spots where big fish always seem to lurk. But owning a kayak may not be enough for many anglers, which is why adding equipment traditionally saved for bigger boats has become an attractive option. We’re going to show you the best kayak fish finder on the market today and help you pick the right one for your ‘yak!

Best Kayak Fish Finder – Guidelines

Given how little space you have in a kayak, compared to a good sized boat, size and weight of a fish finder is an absolute essential factor in determining the right one for you. Screens over 6″ will likely be too bulky. Ideal placement of a fish finder differs for anglers, but the majority of anglers prefer the fish finder between their legs in front of them, as if it were taking the position of a steering wheel of a car. This gives you the best viewing angles as well as easy access to all its functions. Therefore, mounting a fish finder with a screen larger than 6″ may not be possible. Stick with a finder 6″ or less.

Color vs Grayscale Screens?

Conventional wisdom says color screens are more advanced and should be considered superior over grayscale, but that’s simply not true in all cases. Depending on the technology of the fish finder you use, you may prefer grayscale over color. Additionally, grayscale tends to prevent washout from sunlight better than color screens. This isn’t true with all models, however.

GPS or non-GPS?

More and more videos can be seen on YouTube and other video sites of anglers fishing deep waters like the great lakes or the ocean in their kayaks. Now, while that’s not really recommended, it is possible you may need a GPS unit to help navigate where you are. For most kayak anglers, however, the body of water is relatively small and easy to navigate by site. However, with a GPS unit, you will be able to plot your favorite spots so you can return to them when the bite isn’t as strong in a new area. Keep in mind, a GPS unit will be slightly larger than a non-GPS unit, despite the screen size.

Power via marine battery or battery pack?

Some of the more portable fish finders are equipped for common commercial batteries with a waterproof case directly attached to the unit. You may want to go this route if you’d rather not add the weight of a marine battery to your Kayak. Keep in mind, however, the battery life of those units typically last less than five or six hours. Whereas a marine battery will give you hours and hours of use.
