The M190 is an underwater ultrasonic transducer for deep sea surveying and sub-bottom profiling applications, with efficient low-ringing arrays providing excellent performance and detail. It is constructed with a stainless-steel internal chassis for reduced impact damage and seamless SEALCAST urethane housing for long operational life.

The M190 deep water ultrasonic transducer can be mounted as an in-hull installation in a fiberglass hull, or adapted for use as a portable-mount. Stuffing tubes are available to form a watertight conduit for cable routing, in a variety of materials to match all hull types. 4 low-frequency options are available, from 12 kHz to 33 kHz.
