If you are one of those Kayak users who don’t go fishing in the big rivers or sea, You don’t probably need a fish finder with lots of technology. Just finding fish should be a top priority in that case. You won’t need GPS on small rivers or lakes. Get a fish finder with a side-scan feature that can identify fish underwater.
Structure Fishing

Transducer
This is one of the most important things to consider before choosing a fish finder for your Kayak. You might want to choose a brand that matches your Kayak’s design to make the installation faster. All top fish finder manufacturers favor certain kayak designs to install their devices quickly.
