Airmar B75C 20° Tilt Medium CHIRP Thru-Hull Transducer – Navico Compatible

The Airmar B75C-20-M is a 1 kW medium-frequency CHIRP transducer tailored for vessels with hull deadrise between 16° to 24°. Featuring a 20° tilted ceramic element, this thru-hull transducer installs nearly flush to the hull, optimizing sonar performance while minimizing drag at speed. It operates across an 80 to 130 kHz frequency band with a 50 kHz bandwidth, delivering superior target separation, broad mid-depth coverage, and enhanced fish-finding capability.

Constructed with a durable bronze housing and equipped for fiberglass or wood hulls, the B75C-20-M incorporates Airmar’s exclusive Xducer ID® technology for automatic integration and setup with Navico systems.
