Product Overview

Airmar TM185C Transducer

Medium CHIRP With Raymarine 11-Pin

Model: TM185C-M-11R
  • Depth and fast-response water-temperature sensor
  • 1 kW with a maximum depth of 457 m (1,500')
  • Medium frequency: 85 to 135 kHz
  • 50 kHz of total bandwidth from one transducer
  • Covers popular fishing frequencies of 88 and 107 kHz plus everything else in the bandwidth
  • Medium frequency provides excellent shallow to mid-depth performance, bottom detail, and fish-target separation
  • Transom-mount, urethane housing with a stainless steel bracket for installation on outboard and I/O powered boats
  • Also available as thru-hull (B285M, B175M) and in-hull (M135M) models
  • Exclusive Xducer ID® technology

The 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. Operating at a frequency range of 85 to 135 kHz, this transducer reveals fish at medium depths down to 457 m (1,500') and delivers ultra-clear target resolution.
