The Airmar B265LM is a bronze thru-hull CHIRP transducer built for serious offshore and deep-water fishing. Operating across a combined 73 kHz of bandwidth in two frequency bands — low (42–65 kHz) and medium (85–135 kHz) — it covers popular fishing frequencies of 50, 88, and 107 kHz from a single unit. At 1 kW of power, it delivers precise target separation, bottom discrimination, and bait and gamefish identification across a wide range of depths. The included High-Performance Fairing Block maintains broadband performance at speeds exceeding 30 knots (34 MPH). A Mix & Match cable is required and sold separately.
