Airmar TM185C Transducer Medium CHIRP With Humminbird.

Airmar TM185C‑M Medium CHIRP Transom Mount Transducer Series for Humminbird

The Airmar TM185C‑M is a medium‑frequency 1 kW CHIRP transducer engineered for reliable offshore and freshwater performance. With a frequency range of 85 to 135 kHz, it delivers exceptional target clarity, precise fish separation, and clean bottom definition from shallow waters to 457 m (1,500 ft). This balance of coverage and resolution makes it ideal for anglers who fish both mid‑depth and deep zones.

The TM185M features a rugged urethane transducer body and stainless‑steel mounting bracket suitable for outboard and I/O‑powered boats. Integrated Xducer ID® technology automatically optimizes CHIRP sonar settings. Available with Humminbird 9‑Pin, 14‑Pin, and 21‑Pin Mix‑N‑Match cables for seamless connectivity to compatible sounders.
