Rated at 1kW and operating in the medium CHIRP band (85-135kHz), the B175M delivers Garmin CHIRP sonar's clearer target separation and reduced clutter compared with older single-frequency transducers, with a beamwidth of roughly 16° to 11° across its frequency range and a maximum rated depth of about 457m (1,500ft). Beyond sonar, it also includes integrated depth and fast-response water-temperature sensing, feeding both into the connected chartplotter alongside the sonar image. Its bronze housing is suited to fiberglass and wood hulls, and the 8-pin connector is designed to plug into Garmin's chartplotter/sonar network directly or via a Garmin 8-pin mix-and-match adapter cable where a different connector type is needed elsewhere in the system. Being a thru-hull unit, fitting requires cutting/drilling the hull and is normally carried out during a haul-out or new build, with the 12° tilt specifically chosen to match this vessel's deadrise rather than a universal fit.
