Airmars TM185M is a transom-mounted, Chirp-ready transducer designed for offshore fishing and freshwater anglers spending their time in shallow to mid-range depths.

Airmars TM185M is a transom-mounted, Chirp-ready transducer designed for offshore fishing and freshwater anglers spending their time in shallow to mid-range depths.

The medium frequency delivers the right combination of coverage under the boat, extended depth range, and the ability to produce clean and accurate target and structure returns in mid to deeper water.

Medium frequency also provides excellent shallow to mid-depth performance, bottom detail, and fish-target separation. Operating at a frequency range of 85 to 135 kHz, this transducer reveals fish at medium depths down to 457 m (1500′) and gives ultra-clear target resolution.

Notice: Many CHIRP transducers are now made as Mix and Match models. These versions use a common base transducer with an attached 9-meter cable, plus an interchangeable short (1-meter) brand-specific adapter cable. Both parts are needed for an installation. The base transducer can be used with any brand of sounder by selecting the appropriate adapter.

The permanently-attached 9-meter transducer cable ends in an Airmar 12-pin female connector. This cable is run up through the boat to the equipment location. The short adapter cable has an Airmar 12-pin male connector at one end, to connect to the transducer cable, and a brand-specific connector at the other end to connect to the sounder or display.

The Airmar TM185M Transom Transducer is universal and fits in any Fishfinder brand with an extra adapter that is sold separately.
