For logging the water depth, users need a black box for doing this...
There are several systems of navigation instruments on board:
- 1. NMEA-0183 with single GPS and single sounder
- 2. NMEA-0183 export from a chart plotter, with connected GPS and sounder
- 3. NMEA-2000 with connected GPS and sounder
- 4. Chart plotters writing to an SD-card, (W)LAN or USB, with connected GPS and sounder
We need two HW-Loggers:
- NMEA-0183
- NMEA-2000
Skipper with PC and NMEA-0183 can use our SW-Logger (plus RS-232>USB converter).
