Tools required to use a fish finder on a kayak

You might find yourself needing the following tools in order to work a fish finder on a kayak properly:

  • A proper fish finder, i.e. a Humminbird Helix 5
  • A lightweight lithium battery
  • A mount to attach your fish finder to your kayak
  • A power cord to connect your battery and the fish finder

How to attach your fish finder to a kayak

First, you need to keep the fish finder fixed firmly in place so there is no risk of it toppling over the edge of your kayak. For this, you will need a mount, in other words, a device to fix onto your kayak to keep your fish finder safe. For most kayak anglers, it is more convenient to mount the fish finder away from paddles. If it is too close to your paddles, you might find it difficult to move and row your kayak properly in fear that the fish finder will fall into the water. This is why you should place your fish finder next to your rod towards the front of the kayak.

This way, the fish finder will not get in your way, and you will be able to monitor the fish finder’s screen with ease.

You do not need more weight than necessary on your kayak, so a light battery of less than a kilogram is your best option.
