Raymarine B265LM (A80011) is a premium 1kW bronze thru-hull dual-channel CHIRP transducer designed for commercial, tournament, and offshore fishing vessels operating across mid-water depths and deep canyons. Equipped with an internal 8-element ceramic array, it operates simultaneously across Low CHIRP (42 to 65 kHz) for deep-water penetration up to 3,000 ft and Medium CHIRP (85 to 135 kHz) with a wider 16° to 11° beam width for broader coverage under the vessel and detailed bottom tracking. Supplied with a high-performance fairing block, the bronze housing cuts through water turbulence and drag for clear sonar performance at speeds exceeding 30 knots.
