Garmin GDT43 Depth/Temp Transducer with NMEA2000 Adapter delivers reliable water depth and temperature readings through a rugged thru-hull design. This 43 mm transducer is built to endure marine conditions and provides accurate data that supports safer navigation and smarter anchoring decisions.

Designed to retrofit existing Nexus and Silva 43 mm TH43 thru-hull installations, the GDT43 offers a seamless upgrade path for Garmin-enabled vessels. When paired with the included NMEA 2000 adapter, it connects directly to your NMEA 2000 network, allowing depth and temperature information to be displayed on any compatible Garmin chartplotter or instrument display in real time.
