Airmar B265LH Bronze Chirp Thru Hull 1kW w/Fairing Block - Requires Mix and Match Cable

The Airmar B265LH Bronze Chirp Thru Hull 1kW transducer with fairing block is a dual-frequency CHIRP fish finder designed for serious anglers and professional fishing operations. This left-hand threaded unit delivers precise target detection across a wide frequency range, allowing you to identify specific fish species by their acoustic signatures—from deep-water tuna at 60 kHz to squid at 133 kHz and bottom-feeding cod at 175 kHz. The bronze construction withstands harsh saltwater environments, making it ideal for offshore and coastal fishing applications where corrosion resistance is critical.

With 1kW of power output, the B265LH delivers strong sonar returns in both shallow and deep water conditions. The integrated fairing block reduces turbulence and drag during high-speed operation, maintaining accurate readings even at cruising speeds. The thru-hull mount design provides permanent, flush installation without through-deck penetrations that compromise boat structure. This transducer requires a mix-and-match cable configuration, allowing you to match it with your specific fish finder head unit and wiring harness. The bronze housing and stainless fasteners ensure long-term durability in saltwater environments where aluminum and steel components fail.

This transducer suits commercial fishing operations, charter boats, and weekend offshore anglers who demand frequency-tunable sonar capable of depth scanning and species-specific targeting. Whether you're fishing continental shelves, deep canyons, or coastal grounds, the B265LH's dual-frequency CHIRP technology maps structure and identifies fish with the precision serious fishermen require. The 23.2-pound weight and 18-by-7-by-26-inch dimensions reflect professional-grade construction built to last through years of rigorous saltwater service.
