The Airmar B75M is a bronze through-hull CHIRP transducer engineered for serious anglers who demand precision at depth. Operating in the medium-frequency CHIRP band, it delivers up to 50 kHz of total bandwidth from a single installation — capable of bottom detection down to 3,000 m (10,000 ft) with resolution sharp enough to separate individual baitfish from game fish and structure. The 20° tilted design accommodates deadrise hull angles, and built-in Xducer ID® technology ensures seamless sounder pairing. A Mix and Match cable is required and sold separately.
