Airmar B175 0° CHIRP Bronze Thru Hull Transducers with Bare Wire Mix-N-Match Cable
The Airmar B175 series comprises high-performance CHIRP-ready bronze thru-hull transducers designed for boats 8 m (25’) and larger with fiberglass or wood hulls. The transducers feature ceramic elements permanently tilted inside the housing to compensate for the hull deadrise, ensuring the sonar beam is aimed straight down for maximum echo returns without the need for a fairing. Flush/tilted transducers mount through a hole drilled in any fiberglass, metal, or wooden hull with a flush exterior.
