B&G Depth Transducer

[Robifz]

I would like to connect my old B&G Depth Transducer. Is there anything I can use that can decode the electrical signal from the transducer. I would assume it is a propriety B&G signal.

Actisense® DST-2
can decode analog depth signals into NMEA.

You need to know frequency of your transducer to match it with decoder.

Found some code which does it (for NASA depth, but principle should be same).

Here is the project

And another project doing the same:
