Airmar TM185C Transducer Medium CHIRP With Navico.

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

The Airmar TM185C‑M transom‑mount transducer provides versatile medium‑frequency CHIRP performance for offshore and freshwater anglers seeking accurate fish and structure readings at mid‑depth ranges. Operating between 85 and 135 kHz with 1 kW of power, it delivers exceptional target resolution and depth penetration down to 457 m (1,500 ft).

The TM185M balances coverage and clarity for shallow to mid‑depth use and features Airmar’s Xducer ID® technology for auto‑setup with Navico CHIRP‑ready sounders. Built with a urethane acoustic window and stainless steel mounting bracket, it fits planing and displacement hulls on outboard or I/O‑powered boats.
