Airmar TM185C Transducer High Wide CHIRP With Humminbird.

Airmar TM185C‑HW High Wide CHIRP Transom Mount Transducer Series for Humminbird

The Airmar TM185C‑HW delivers premium 1 kW high‑frequency CHIRP performance for inshore and pelagic fishing applications. Operating across a 150 – 250 kHz band with a constant 25° beamwidth, it offers exceptional target resolution, broad under‑boat coverage, and crisp fish arches — providing up to twice the coverage area of narrow‑beam designs.

Designed for outboard and I/O powered boats up to 10 m (32 ft), the TM185C‑HW is built with a durable urethane housing and stainless‑steel mounting bracket. Its integrated fast‑response temperature sensor ensures precise data feedback, while Airmar’s Xducer ID® technology enables smart auto‑setup with compatible Humminbird CHIRP sonar systems.
