BII-7570 Side Scan Transducer: Underwater Imaging

Benthowave's side scan transducers are designed for use in underwater imaging, sea/river/lake-floor mapping, target location, mine hunting, fisheries... The beam covers wide across-track swath and provides high along-track spatial resolution in tens or hundreds meter range. Acoustic image of underwater bottom is achieved at grazing angles of incidence. (Note: BII does not provide hardware and software for data sampling and processing.)

Optional mounting parts are available for installation on portable-mounting apparatus, submersibles, pipe, tank or vessel.
An impedance matching transformer is optional to provide correct impedance match to load requirements of power amplifiers.
A Transmit & Receive Switch is available to be integrated inside transducer for amplifying the received sounds and driving long cable.
