PM111LH Depth/Temperature Transducer

Part # PM111LH

The PM111LH is a urethane, pocket or keel-mounted CHIRP transducer, ideal for sportfishing and commercial vessels. This dual-channel transducer combines Low CHIRP frequencies to accurately track the bottom in deep water, and High CHIRP for great resolution in shallower water. 

Key Features

  • 38-75 kHz Low CHIRP with 19-10° beam width
  • 130-210 kHz High CHIRP with 8-4° beam width
  • Up to 1200 m (4000 ft) range with Low CHIRP
  • Narrow High CHIRP is great at pinpointing structure in shallower water
  • 16 internal broadband ceramics
  • Pocket/Keel-mounted with urethane housing and yellow in-hull tank (can retrofit to existing R299 tanks)
  • Suitable for solid fiberglass hulls
  • Ideal for sportfishing and commercial vessels
  • Recommended for use with the BSM-3 broadband sounder module
Where To Buy



    Dual Channel CHIRP

    Using pulsed transmissions swept across a range of frequencies, CHIRP technology delivers target resolution and depth penetration superior to traditional single-frequency sonar. This dual-channel CHIRP transducer operates in the 38-75 kHz Low CHIRP frequency range with a 19-10° beam width, and the 130-210 kHz High CHIRP frequency range with a 8-4° beam width. With Low CHIRP, the PM111LH provides an operating depth of up to 1200 m (4000 ft).

    Depth/Temperature

    One sensor does it all. Able to measure both depth and temperature in a single package, the PM111LH simplifies installation and requires just one connection to your echosounder module or multifunction display.

    Mounting

    With urethane housing, the PM111LH is suitable for pocket or keel mounting in solid fiberglass hulls. Pocket- or keel-mounting installs the transducer flush to the hull in a custom pocket, providing minimal drag and good high-speed performance. Boat builders may incorporate this transducer in new hulls, and aftermarket installation is possible by routing a suitable hole and fiberglassing the transducer in place.
