R111LH Depth/Temperature Transducer

Part # R111LH

The R111LH is a urethane, in-hull, 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
  • In-hull/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 R111LH 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 R111LH simplifies installation and requires just one connection to your echosounder module or multifunction display.

    Mounting

    With urethane housing, the R111LH is suitable for in-hull, pocket or keel mounting in solid fiberglass hulls.

    In-hull or “shoot-thru-hull” transducers don’t require a hole to be drilled in your boat’s hull for installation, and offer good high-speed performance and ease of maintenance, but reduced maximum depth and fishfinding performance versus thru-hull, transom, or other in-water installations.

    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.
