A-DST-2-150 Analogue to NMEA0183 converter




Analogue to NMEA0183 converter for 150kHz transducers

It works with NMEA 0183 compatible devices, such as chart plotters, radars or an on-board PC. In addition, it can be calibrated via a PC to match various sensors and installations.
Using a DST with an existing depth transducer can be much more cost-effective than having to lift the boat out of the water to change the transducer skin fitting. Not only does this save money, but it also saves you time.
