Collection: Marine Navigation & Instruments - Transducers

Turn underwater signals into information you can use.

Explore marine transducers and accessories designed to support fishfinders, sonar systems, depth sounders and compatible marine electronics. The right transducer is essential for gathering accurate underwater data, from depth and water temperature to fish targets and bottom structure.

Shop CHIRP transducers, thru-hull transducers, transom-mount transducers, in-hull transducers, trolling motor transducers, side-imaging and down-imaging transducers, depth and temperature sensors, mounting hardware, cables and transducer accessories for fishing boats, powerboats, sailboats, yachts and other compatible vessels.

Whether you're replacing an existing transducer, upgrading your sonar capabilities or installing a new fishfinder or sounder system, Roam & Harbor makes it easier to find transducers and installation accessories for your marine electronics setup.

Always verify sonar technology, frequency, power rating, mounting style, hull material, connector type, deadrise requirements and electronics compatibility before selecting a transducer.
