The Airmar B175M is a bronze thru-hull CHIRP transducer built for serious anglers and working captains who demand precise underwater imaging. Operating across a 50 kHz bandwidth in the medium CHIRP range, it resolves individual baitfish, game fish, and structure with far greater clarity than conventional single-frequency units — all from a single thru-hull installation. The 20° tilt accommodates deadrise angles and keeps the beam perpendicular to the water for accurate readings. A Mix and Match cable (sold separately) is required for connection to your sounder.
