Where Does the Fishfinder Transducer Go on a Kayak?

If you enjoy kayak fishing, you know how important it is to have the right equipment to enhance your fishing experience. One crucial piece of gear that can greatly improve your chances of success is a fishfinder.

A fishfinder helps you locate fish underwater by sending out sound waves and displaying the information on a screen. However, to make the most of your fishfinder, you need to install the transducer in the correct location on your kayak.

What is a Fishfinder Transducer?

A transducer is an essential component of a fishfinder system. It is responsible for transmitting and receiving sonar signals, enabling you to see what lies beneath the surface of the water. The transducer emits sound waves that bounce off objects underwater and then returns these signals to your fishfinder unit for interpretation.

Why is Transducer Placement Important?

The placement of your fishfinder transducer plays a crucial role in its performance. Placing it in the right spot ensures accurate readings and prevents interference or signal loss. The goal is to position the transducer where it can maintain a clear view of the water column without obstruction from your kayak or other objects.

1. Inside Hull Mounting

Inside hull mounting is one way to install your transducer without affecting the external appearance of your kayak. This method involves attaching the transducer inside the hull using adhesive or epoxy.

While inside hull mounting protects your transducer from potential damage caused by rocks or debris, it may result in reduced sensitivity due to signal loss through the hull material.

2. External Transducer Mounting

External transducer mounting is a popular choice among kayak anglers. This method involves attaching the transducer to the outside of your kayak’s hull.

Mounting the transducer externally ensures maximum sensitivity and accurate readings since there are no obstacles between the transducer and the water.

Tips for Transducer Placement

  • Mount the transducer as close to the centerline of your kayak as possible for a balanced sonar performance.
  • Avoid placing the transducer too close to other objects, such as scupper holes or rudders, to prevent interference.
  • If mounting externally, use a transducer arm or bracket to position it securely and adjust its depth in the water.


Proper placement of your fishfinder transducer is essential for accurate sonar readings and an enhanced fishing experience. Whether you choose inside hull mounting or external mounting, ensure that your transducer has an unobstructed view of the water column. By following these tips and experimenting with different placements, you can optimize your fishfinder’s performance on your kayak and increase your chances of hooking that big catch!
