10 Best Kayak Fish Finders To Buy In 2024


Which Fish Finder For Kayak Is Best?

Getting a good fish finder is great but it is important to understand the general setup of fish finders and how to install them on your kayaks.

Different kayaks require different modifications when installing a fish finder kit. Generally, fish finders have 3 general parts:

  1. The display screen
  2. The transducer
  3. The battery

The display screen

The display screens vary depending on the fish finder. However, it is important to attach the screen to a point where you can easily read the display information and navigate the fish finder conveniently. 

The display screens are usually fixed to a compatible mount before installing on your kayak. Common placement options for the display are; the center console, a side of the foot-well, gunwale, etc.

When deciding where to install your fish finder display screen, ensure it is a place that would not be difficult to run the transducer and battery wires. It is also important that it is a comfortable position for you the user and it is within range.

The transducer

Many modern kayaks have taken into account the possibility of a fish finder being used with the kayaks. If your kayak doesn’t come with a built-in kayak hole or if the hole doesn’t fit the transducer you own, the best option is to get a suitable transducer mount to prevent unnecessary drilling of your kayak.

Installing the battery

Where to place the battery is a choice that many kayak anglers struggle with. Regardless of where you place the battery, it is important that the battery is placed in a waterproof casing (that can be bought or made) to protect the battery from water. 

Many times, the battery is placed in the kayak not far from the seat. Update your fishing kit with one of the fish finders reviewed in this article and enjoy a better catch during your subsequent fishing trips!
