Airmar B75C- 12d Tilt CHIRP With Mix-n-Match Plug.

Airmar B75C-12 Tilt Bronze Thru Hull Series (Medium & Low CHIRP)

The Airmar B75C-12 Tilt transducers are designed for smaller boats up to 8 m (25’) with fiberglass or wood hulls, featuring a durable bronze housing and a fixed 12° element tilt. These transducers compensate for hull deadrise angles from 8° to 16°, orienting the sonar beam directly downward for maximum accuracy and echo returns. Their low-profile design ensures excellent performance at boat speeds and high-resolution sonar images.

Available in Medium and Low CHIRP frequency bands, these transducers provide outstanding bottom detail and fish separation, ideal for commercial and recreational fishing. Both models include depth and fast-response water-temperature sensors.
