M265LH Depth Transducer

Part # M265LH

The M265LH is a plastic/urethane, in-hull 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

  • 42-65 kHz Low CHIRP with 25-16° beam width
  • 130-210 kHz High CHIRP with 10-6° beam width
  • Up to 1200 m (4000 ft) range with Low CHIRP
  • Narrow High CHIRP is great at pinpointing structure in shallower water
  • 8 internal broadband ceramics
  • In-hull with plastic/urethane housing and yellow in-hull tank (can mount in existing M260 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 42-65 kHz Low CHIRP frequency range with a 25-16° beam width, and the 130-210 kHz High CHIRP frequency range with a 10-6° beam width. With Low CHIRP, the M265LH provides an operating depth of up to 1200 m (4000 ft).


    With plastic/urethane housing, the M265LH is suitable for in-hull 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.
