The Airmar B275MWHW is a bronze thru-hull CHIRP transducer that fuses medium and high frequency bandwidths into one housing, delivering wider bottom coverage than any other 1 kW transducer on the market. Medium frequencies (60–100 kHz) with ultra-wide beamwidths push depth capability to 396 m (1,300 ft), making it a powerful scouting tool for deep-target species, while the high-frequency band (150–250 kHz) provides 25° wide beamwidths for sharp fish-target separation and clear arches in the upper water column — twice the coverage of standard high-frequency units. A high-performance fairing block is included for boats over 8 m (25 ft), and a Mix & Match cable is required (sold separately).
