There is this piece of kit that can drive many old depth sounders and turn them into NMEA0183:

Shouldn’t be too tricky to go from there to RPi.

I just received mine, so I haven’t had the the to plug it in yet. The plan is to digitise our old NASA depth sounder (I bought the DST-2-150 because of this) and VDO Sumlog paddle wheel sensor.
