PM275LH-W Depth/Temperature Transducer

Part # 000-11686-001

The PM275LH-W is a pocket or keel-mounted 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

  • 42-65 kHz Low CHIRP with 25-16° 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
  • 8 internal broadband ceramics
  • Pocket/Keel-mounted with flat-face design
  • Suitable for fiberglass hulls only
  • 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 42-65 kHz Low CHIRP frequency range with a 25-16° beam width, and the 150-250 kHz High CHIRP frequency range with a 25° beam width. With Low CHIRP, the PM275LH-W provides an operating depth of up to 1200 m (4000 ft).

    Wide Angle CHIRP

    Ideal for anglers, the PM275LH-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 PM275LH-W simplifies installation and requires just one connection to your echosounder module or multifunction display.

    Mounting

    The PM275LH-W is suitable for pocket or keel mounting in fiberglass hulls only. 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.
