The Garmin B275LH-W is an Airmar-built bronze thru-hull transducer that combines wide coverage with deep-water capability in a single dual-frequency CHIRP-ready unit. Spanning 123 kHz of total bandwidth, it covers the 50 kHz and 200 kHz fishing frequencies along with the full range in between. A fixed 25° wide beam at high frequency delivers roughly twice the coverage of a standard narrow-beam transducer, improving fish detection across the upper water column. The included high-performance fairing maintains broadband performance at speeds above 30 knots, making this transducer well suited for larger offshore vessels.
