Airmar TM185M – Chirp-ready Transom Mount Transducer

Airmar’s 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.

Features

  • Depth and fast-response water-temperature sensor
  • 1 kW with a maximum depth of 457 m (1,500′)
  • Medium frequency: 85 to 135 kHz
    • 16° to 11° beamwidth
  • 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 Benefits of AIRMAR’s Chirp-ready Transducers

• One broadband transducer covers up to 117 kHz of bandwidth – greater opportunities to detect fish in the water column
• Superior resolution – precise separation between baitfish and gamefish represented on the display with crisp images
• Enhanced bottom fishing – resolve targets close to the bottom or near structures/wrecks
• Amazing detail – recognize haloclines and thermoclines
• Improved signal-to-noise ratio – find fish and track bottom at high boat speeds

Benefits of Transom Mount Transducers

Transom models are best suited for small and trailered vessels where a thru-hull installation is not practical. Perfect for freshwater boat styles and centre consoles. Simple to install and ideal for small trailered vessels where a thru-hull may interfere with loading.
• Simple installation on the transom of the boat
• Great performance at boat speeds below 30 knots
• Easy maintenance and low-cost replacement

Why does Frequency Matter?

Selecting the best frequency for your specific application is very important. The good news is that once you know what frequency will work best for the type of fishing you do, there’s an AIRMAR transducer designed to maximize the performance of your sounder.
AIRMAR Chirp transducers are available in various frequency combinations:

Dual Band:

  • Low/High (LH)
  • Low/Medium (LM)
  • Low/High Wide (LHW)
  • Low Wide/Medium (LWM)
Single Band:

  • Low
  • Medium
  • High
  • HighWide

Low Frequency = Greater Depth (ex. 42-65 kHz)

• Sound waves will not present as clear a picture of the bottom on the display but will sound down in very deep areas where high-frequency sound waves cannot reach
• Provides greater depth range, wider beamwidth, and ultimately more coverage under the boat
• Chirp signal processing technology used with AIRMAR broadband, Chirp-ready transducers provide more detail at greater depths and are less susceptible to noise
• Great for operating at high boat speeds

High Frequency = Greater Detail (ex. 130-210 kHz)
• More sensitive to small targets and will send back detailed information which will display as crisp, high-resolution images on the echosounder screen
• Best for shallower water and is popular with anglers fishing at depths less than 1500 feet

Medium Frequency = The Best of Both Worlds (ex. 80-130 kHz)
• Provides the ability to sound deeper than the high frequency, along with better resolution than the low frequency
• Wider beam than the high frequency, achieving more coverage under the boat and greater opportunity to find fish
• Clear images at higher boat speeds
