The Airmar B275C-LHW is a bronze thru-hull transducer engineered for anglers who want maximum bottom coverage and sharper fish returns across the water column. Operating across both a low CHIRP band (42–65 kHz) and a high wide CHIRP band (150–250 kHz), it delivers a constant 25° beam angle throughout the entire high-frequency range — roughly twice the coverage of standard narrow-beam high-frequency CHIRP transducers. The result is crisper, larger target images on compatible CHIRP-ready echosounders, with improved detection of fish that can go unnoticed on narrower units. A Mix & Match cable is required and sold separately.
