The Garmin GDT 43 is a thru-hull transducer that can read water depth and water temperature. It can retrofit an existing Nexus and Silva 43 mm thru-hull transducer (TH43). Comes with the NMEA 2000® adapter which lets the GDT 43 connect directly to the NMEA 2000 network, and the information can be displayed on a compatible Garmin chartplotter, multifunction display or instrument display.
