The Airmar B75M brings CHIRP sonar technology to bronze thru-hull installations, delivering bottom detection to depths of 3,000 m (10,000 ft) with resolution fine enough to separate individual baitfish from game fish and underwater structure. Operating across a medium CHIRP band of 80–130 kHz, this single transducer covers 50 kHz of total bandwidth — including the popular fishing frequencies of 88 and 107 kHz — all in one hull penetration. A built-in fast-response water temperature sensor and Airmar's exclusive Xducer ID® technology round out a capable package suited for fiberglass or wood hulls up to 8 m (25 ft). A compatible Mix and Match cable is required and sold separately.
