Airmar B265LM Bronze Chirp Thru-Hull Transducer 1kW w/Fairing Block - Mix & Match Cable Needed

The Airmar B265LM Bronze Chirp Thru-Hull Transducer 1kW with Fairing Block is a professional-grade fishfinding solution built for serious anglers and boaters who demand reliable sonar performance in freshwater and saltwater environments. This through-hull bronze transducer excels at delivering crisp, detailed bottom structure and fish targets at depths where conventional transducers struggle with clarity. Whether you're working shallow flats, offshore drop-offs, or everything in between, the B265LM combines durability with advanced CHIRP frequency technology to give you the competitive edge on the water.

At 1 kilowatt of power output, this Airmar transducer delivers exceptional range and resolution without excessive noise interference that can mask weak returns. The CHIRP (Compressed High-Intensity Radar Pulse) transmission protocol transmits across a frequency band rather than a single frequency, yielding dramatically improved target separation and bottom definition—critical for distinguishing baitfish from structure and identifying suspended game fish. The bronze casting is both corrosion-resistant and provides excellent acoustic coupling, while the included fairing block streamlines water flow to minimize turbulence and cavitation noise that degrades sonar quality at speed. Note that this model requires a compatible Mix & Match cable assembly (sold separately) for connection to your fishfinder processor unit.

The B265LM is ideal for anglers upgrading legacy sonar systems or building a custom rigging from the transducer up. Its through-hull installation requires a properly sized thru-hull hole and careful bedding to prevent leaks, making professional installation recommended for those unfamiliar with marine wiring and sealing protocols. This transducer pairs seamlessly with Airmar-compatible fishfinder heads and is especially valuable on boats running open water fishing or tournament applications where sonar clarity directly impacts catch success. Verify cable type and connector compatibility with your specific fishfinder before purchase to ensure proper integration with your existing electronics platform.
