Garmin GDT 43 Depth & Temperature Sensor
This thru-hull transducer measures water depth and temperature. It's designed to retrofit existing Nexus and Silva 43 mm thru-hull transducers (TH43). The included NMEA 2000® adapter allows the GDT 43 to connect to NMEA 2000 networks, enabling data to be displayed on compatible Garmin chartplotters or instrument displays.
