The GDT™ 43 NMEA 2000® depth and temperature transducer is a thru-hull mounted sensor that delivers stable and accurate water depth and temperature readings directly to your boat network. The transducer is particularly well-suited for retrofitting, as it fits into existing Nexus and Silva 43 mm thru-hull installations (TH43), making the upgrade simple and cost-effective.
With the included NMEA 2000® adapter, the GDT™ 43 can be connected directly to an NMEA 2000 network, allowing measurement data to be displayed on a compatible Garmin chartplotter or instrument display. The thru-hull design ensures reliable data—even at higher speeds—and makes the transducer ideal for both sailboats and powerboats where precision and network integration are essential.
