Furuno B265LH Bronze Thru-Hull CHIRP Transducer - 12-Pin

The Furuno B265LH Bronze Thru-Hull CHIRP Transducer with 12-Pin connector is a professional-grade sounder head engineered for serious anglers and boat operators who demand reliability and imaging clarity in all water conditions. After decades on the water, you know that transducer quality directly impacts fish detection and bottom mapping—this bronze through-hull design is built to deliver consistent broadband CHIRP performance across dual frequency bands. Furuno's CHIRP technology produces frequency-modulated pulses that penetrate thermoclines and return crisper target definition than traditional narrowband systems.

The B265LH operates across a low-frequency band of 42–65 kHz for deep-water scanning and wide beam patterns, paired with a high-frequency band of 130–210 kHz for shallow-water detail and precise target separation. Bronze construction resists corrosion and galvanic decay in saltwater environments, while the thru-hull mounting style minimizes transducer noise and hull interference that plague transom-mount systems. The 12-pin connector ensures secure, weatherproof integration with compatible Furuno CHIRP fish finder displays, delivering stable power and clean signal transmission even in rough seas and extended offshore operations.

This transducer is ideal for commercial fishing vessels, tournament bass boats, offshore cruisers, and dedicated saltwater anglers running Furuno broadband CHIRP systems. Installation requires a properly sized thru-hull penetration and compatible Furuno CHIRP display unit; consult your boat's specifications and Furuno's installation guide to confirm hull material compatibility and cable routing. The 24-pound assembly demands secure mounting and professional installation to ensure optimal sounder performance and hull integrity during extended deployments.
