R109LH-W Depth/Temperature Transducer

Part # R109LH-W

The R109LH-W is a urethane, thru-hull CHIRP transducer, ideal for sportfishing and commercial vessels 8 m (25 ft) and up. This dual-channel transducer combines Low CHIRP frequencies to accurately track the bottom in deep water, with High CHIRP at a constant 25° beam width for the best resolution and coverage in the upper water column and in shallower depths.

Key Features

  • 37-75 kHz Low CHIRP with 19-10° beam width
  • 150-250 kHz High CHIRP with wide 25° beam for excellent fish targets
  • Up to 1200 m (4000 ft) range with Low CHIRP
  • 16 internal broadband ceramics
  • Thru-Hull with urethane housing, stuffing tube and high-performance fairing (can retrofit to existing R99 installations)
  • Suitable for fiberglass, wood and metal hulls
  • Ideal for sportfishing and commercial vessels 8 m (25 ft) and up
  • 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 37-75 kHz Low CHIRP frequency range with a 19-10° beam width, and the 150-250 kHz High CHIRP frequency range with a 25° beam width. With Low CHIRP, the R109LH-W provides an operating depth of up to 1200 m (4000 ft).

    Wide Angle CHIRP

    Ideal for anglers, the R109LH-W’s wide-angle technology delivers a constant 25° beam width across the transducer’s 150-250 kHz High CHIRP frequency range. This achieves up to double the coverage beneath your boat, and provides enhanced fish detection in the upper water column, versus the narrower beam of other high-frequency CHIRP transducers.

    Depth/Temperature

    One sensor does it all. Able to measure both depth and temperature in a single package, the R109LH-W simplifies installation and requires just one connection to your echosounder module or multifunction display.

    Mounting

    With urethane housing, the R109LH-W is suitable for thru-hull mounting in fiberglass, wood and metal hulls. Thru-hull mounting places the transducer in the water on the outside of your boat’s hull; a hole must be drilled for installation, and a fairing block is required to ensure proper alignment. This typically offers the best depth measurement and fishfinding performance.
