Raymarine B265LH (A80010) is a premium 1kW bronze thru-hull dual-channel CHIRP transducer engineered for commercial, tournament, and offshore sport-fishing vessels seeking maximum depth performance and target resolution. Equipped with an internal 8-element ceramic array, it operates simultaneously across Low CHIRP (42 to 65 kHz) for extreme deep-water bottom tracking down to 3,000 ft and High CHIRP (130 to 210 kHz) with a narrow 10° to 6° beam width for crisp target separation and structure detail. Supplied with a custom high-performance fairing block, the B260-style bronze housing minimizes drag, cavitation, and water turbulence for clear sonar performance at speeds over 30 knots.
