Garmin GDT43 Thru Hull Transducer with NMEA 2000

The Garmin GDT-43 is a thru-hull transducer that can read depth and water temperature. This transducer only suit certain models of Garmin Sounders. To make sure you have a compatible sounder please use the 'Suits' tab below or check that your unit has an 8 pin plug connection. This unit comes with an adapter to connect your transducer up to a NMEA 2000 system if you have one on your boat.

This Garmin thru-hull transducer can read water depth and water temperature. It can retrofit an existing Nexus and Silva 43 mm thru-hull transducer (TH43).

We recommend you also purchase some marine sealant to stop any water ingress behind the transducer (see related products below).
