The Airmar B275C-LHW is a bronze thru-hull transducer designed for CHIRP sonar systems, delivering low-frequency (42-65 kHz) depth performance up to 3,000 feet and high-wide frequency (150-250 kHz) coverage to 500 feet with a constant 25° beamwidth. It requires a separate Mix & Match cable for compatibility with various fishfinders and includes a high-performance fairing for optimal speed over 30 knots.
