Airmar B275C-LHW Bronze Thru-Hull - Low & High Wide Frequency - Requires Mix & Match Cable

The Airmar B275C-LHW Bronze Thru-Hull transducer delivers dual-frequency sonar performance in a single compact unit, combining low and high wide-frequency capability to maximize bottom coverage and target detection. Bronze construction provides superior corrosion resistance in saltwater environments, making this thru-hull transducer ideal for both freshwater and offshore applications where durability and consistent performance are non-negotiable.

The B275C-LHW features Airmar's wide-beam CHIRP technology, operating across a 150–250 kHz frequency range with a constant 25° beam width. This wider beam angle effectively doubles the seafloor coverage under the boat compared to standard transducers, allowing anglers to scan larger areas without sacrificing detail or clarity. The high-frequency capability excels at detecting structure, baitfish, and bottom composition in shallow to moderate depths, while the integrated low-frequency element handles deeper water penetration and long-range target acquisition. CHIRP-ready echosounders benefit from the broadband signal characteristics, delivering superior target separation and noise rejection across the frequency spectrum.

This transducer suits serious anglers, commercial operators, and boat owners who depend on reliable sonar performance in variable water conditions. The bronze construction withstands prolonged salt-air exposure without compromising signal quality or mechanical integrity. Note that installation requires a mix-and-match cable (sold separately), allowing customization to fit your specific fishfinder or sonar unit. Verify cable compatibility with your electronics before purchasing to ensure seamless integration.

Airmar transducers are engineered to OEM standards and widely trusted across the boating industry. The B275C-LHW represents a professional-grade solution for anglers upgrading their sonar capability or replacing worn equipment on established vessels.
