Garmin GDT 43 Depth & Tempreture Thru-Hull Transducer

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