The Airmar B275LH-W brings dual-band CHIRP sonar to Garmin-equipped vessels through a bronze thru-hull housing built for serious fishing. The high-wide band holds a constant 25° beam across its entire 150–250 kHz range, delivering twice the water-column coverage of typical narrow-beam transducers along with sharp fish arches and strong bottom detail to 152 m (500'). The low band spans 42–65 kHz with 1 kW of power for reliable depth readings down to 914 m (3,000'). Together, the two bands cover 123 kHz of total bandwidth from a single transducer—including the popular 50 kHz and 200 kHz fishing frequencies. A high-performance fairing is included and keeps broadband performance stable at speeds above 30 knots. Patented Xducer ID® technology and a Garmin 12-pin Mix & Match connector round out the package. Suitable for fiberglass or wood hulls 8 m (25') and above.
