TM265LM Depth/Temperature Transducer

Part # TM265LM

The TM265LM is a transom-mounted CHIRP transducer, ideal for outboards and I/O vessels 8-12 m (25-40 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

  • 42-65 kHz Low CHIRP with 25-16° beam width
  • 85-135 kHz Medium CHIRP with 16-11° beam width
  • Up to 1200 m (4000 ft) range with Low CHIRP
  • 8 internal broadband ceramics
  • Transom-mounted (can retrofit to existing TM258 & TM260 brackets)
  • Suitable for fiberglass, wood and metal hulls
  • Ideal for outboards and I/O vessels 8-12 m (25-40 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 42-65 kHz Low CHIRP frequency range with a 25-16° beam width, and the 85-135 kHz Medium CHIRP frequency range with a 16-11° beam width. With Low CHIRP, the TM265LM 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 TM265LM simplifies installation and requires just one connection to your echosounder module or multifunction display.

    Mounting

    The TM265LM is suitable for transom mounting with fiberglass, wood and metal hulls. Transom-mounted transducers are designed for smaller outboard and I/O boats, and are well suited to planing hulls. Transom mounting offers simple installation and maintenance, and the transducer can be adjusted easily to compensate for transom angle.
