In-Hull Transducers

In-Hull Transducers – Reliable Sonar Without Hull Penetration

In-hull transducers are an ideal solution for boaters seeking accurate sonar performance without drilling through the hull. Designed to be mounted inside the boat, these transducers transmit sonar signals through solid fiberglass hulls, making them perfect for clean installations and minimal drag.

Commonly used on fiberglass boats, in-hull (also known as shoot-through) transducers provide reliable depth readings and bottom tracking while protecting the unit from damage caused by debris or marine growth. With no external components exposed to water, they require less maintenance and offer long-lasting durability.

These transducers are best suited for depth sounding and basic sonar functions, as they do not support water temperature readings or advanced side imaging. However, they deliver consistent performance for cruising, navigation, and general fishfinding applications.

Compatible with leading brands like Airmar, Garmin, Raymarine, and Furuno, in-hull transducers are available in various power ratings and frequencies to match your specific sonar system.
