Airmar TM185C Transducer Medium CHIRP With Garmin.

Airmar TM185C‑M Medium CHIRP Transom Mount Transducer Series

The Airmar TM185C‑M delivers versatile medium‑frequency CHIRP performance for anglers targeting a wide range of depths. Optimized for both offshore and inland applications, the TM185M offers the ideal balance between deep‑water reach and detailed mid‑depth clarity. Operating from 85 to 135 kHz with 1 kW of power, it cleanly identifies fish and bottom structures down to 457 m (1,500 ft).

Airmar’s Xducer ID® technology allows sonar systems to automatically configure the ideal settings for maximum performance. The rugged urethane body with stainless mounting bracket supports 3° to 21° transom angles, making it a reliable choice for outboard and I/O powered vessels.
