R509LM Depth/Temperature Transducer

Part # R509LM

The R509LM is an epoxy, thru-hull CHIRP transducer, ideal for sportfishing and commercial vessels up to 12 m (40 ft) in length. This dual-channel transducer combines Low CHIRP frequencies to accurately track the bottom in deep water, and Medium CHIRP for greater resolution with minimal loss of depth penetration.

Key Features

  • 28-60 kHz Low CHIRP with 23-9° port/starboard beam width (11-5° fore/aft)
  • 80-130 kHz Medium CHIRP with 13-8° beam width
  • Up to 1200 m (4000 ft) range with Low CHIRP
  • 25 internal broadband ceramics
  • Thru-hull with epoxy housing, stuffing tube and high-performance fairing (can retrofit to existing R209 installations)
  • Suitable for fiberglass, wood and metal hulls
  • Ideal for sportfishing and commercial vessels up to 12 m (40 ft) in length
  • 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 28-60 kHz Low CHIRP frequency range with a 23-9° port/starboard beam width (11-5° fore/aft), and the 80-130 kHz Medium CHIRP frequency range with a 13-8° beam width. With Low CHIRP, the R509LM 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 R509LM simplifies installation and requires just one connection to your echosounder module or multifunction display.

    Mounting

    With epoxy housing, the R509LM 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.
