Airmar B75C- 12d Tilted Medium CHIRP Si-Tex 8-Pin Cables.

Airmar B75C 12° Tilt Medium and Low CHIRP Bronze Thru Hull Transducers with Si-Tex 8-Pin Mix-N-Match Cable

Airmar’s B75C series features high-performance bronze thru-hull transducers designed with a 12° tilted ceramic element to compensate for hull deadrise, ensuring the sonar beam is oriented straight down for maximum echo returns. These low-profile transducers are ideal for boats up to 8 m (25’) with fiberglass or wood hulls, delivering detailed bottom detection and fish separation through advanced CHIRP sonar technology.
