Raymarine TM185 1Kw Depth and Temperature CHIRP Transom Mount Series.

Raymarine TM CHIRP Transom Mount Transducer Series
High‑Performance Depth and Temperature Transducers by AIRMAR®

Raymarine’s TM CHIRP transducers from AIRMAR® deliver exceptional target definition, true CHIRP clarity, and wide coverage for anglers and yachtsmen. Each model is optimized for specific depth ranges and fishing applications using AIRMAR’s Xducer ID® technology, which provides automatic calibration and peak performance with compatible CHIRP sonar modules. Compact urethane housings and stainless brackets make these transducers ideal for smaller planing or trailered boats where a thru‑hull installation is not practical.
