Shallow Fishing

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.

Structure Fishing

Choose a fish finder with DI and SI sonar technology if you are going to fish on structures like humps or reefs. These technologies will help you to keep your Kayak on track and identify solid objects. If you are going to fish with your Kayak on the sea, choosing a fish finder with good GPS technology would be your best option.

Average Mounting Space

When You’re paddling or casting your Kayak, You would not want your fish finder blocking your view. That would be irritating. Depending on Your kayak’s size choose a fish finder with an average to small display size.

A 5inch display size should be ideal. Keep that in mind that you can read the details on display comfortably. After making space for all the mounts, ram, battery, and cables make sure you have enough space on your Kayak to keep your rod, reels, and tackles.

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.

Waterproof

You might wanna choose a fish finder that is easily portable and waterproof. A kayak is a small boat. So, it is possible to accidentally drop something on the water. That’s why a waterproof fishfinder would be a great choice.
