The Garmin NMEA2000 adapter for GDT 43 is used to connect the Garmin GDT 43 depth and temperature transducer directly to an NMEA 2000 network. The data can then be shown on a compatible Garmin chartplotter, multifunction display or instrument display. Garmin’s installation instructions state that the GDT 43 connects to the NMEA 2000 network via the NMEA 2000 adapter.
