Actisense DST 2 Depth Sounder Module

Breathe new smart digital life into your old or new transducers, with digital signal processing technology.

The Actisense DST 2 Depth Sounder Module is the market-leading way to take analogue transducers into the digital age. When used with new or existing transducers fitted to a vessel, the DST-2 digitises depth, speed and temperature transducer signals into NMEA data to deliver best-in-class seabed tracking. When used with an existing installed transducer, the frequency of the DST-2 must match that of the transducer. Typical frequencies used by manufacturers are 150 kHz (common in the UK and EU) and 170 kHz and 200 kHz (more common in the USA).

The Actisense DST 2 Depth Sounder Module is ideal for operation with any NMEA 0183 compatible devices, such as chart plotters, radars or an on-board PC. In addition, it can be calibrated via a PC for various sensors and installations.
