Airmar B117 50/200kHz 600W Bronze Thru-Hull Transducer

The Airmar B117 (50/200kHz, 600W, Mix & Match, 0° Deadrise) is Airmar's entry-level transducer, featuring a single dual-frequency ceramic element in a low-profile bronze housing. It is designed for boaters who want a nearly-flush design minimizing drag, extending only about 3/16 inch outside the hull.

This transducer provides depth-only or depth-and-temperature sensing, with 50 kHz (45° beamwidth, 1200' depth) and 200 kHz (12° beamwidth, 700' depth) dual-frequency elements. A right-angle cable exit saves space and protects the transducer if stepped on, with an included rubber washer for tightening the hull nut on irregular surfaces.
