The Garmin B275LH-W is an Airmar-built bronze thru-hull transducer engineered for anglers who need both wide coverage and deep-water reach from a single unit. Its dual-frequency CHIRP-ready design spans 123 kHz of total bandwidth, covering popular fishing frequencies at 50 and 200 kHz and everything in between. The fixed 25° wide beam at high frequency delivers twice the coverage of most narrow-beam alternatives, making it especially effective for spotting fish in the upper water column during inshore and pelagic fishing. A high-performance fairing is included to maintain broadband performance at speeds exceeding 30 knots.
