Airmar TM185C Transducer High Wide CHIRP Transom Mount Transducer Series With Garmin.

Airmar TM185C High Wide CHIRP Transom Mount Transducer Series

The Airmar TM185C‑HW delivers professional‑grade high‑frequency CHIRP performance in a compact transom‑mount design. Perfect for inshore or near‑offshore fishing, it offers superior resolution, precise target separation, and wide fish detection coverage in shallow to mid‑depth waters. The constant 25° beamwidth across the 150–250 kHz band dramatically increases under‑boat visibility, allowing anglers to view more fish arches and detail simultaneously.

Built with a durable urethane housing and stainless steel bracket, this 1 kW transducer is suited for installation on outboard and I/O powered boats up to 10 m (32 ft). It includes a fast‑response temperature sensor, supports Xducer ID® technology, and connects via Garmin Mix‑N‑Match 8‑Pin or 12‑Pin cables.
