Garmin GST 43 thru-hull transducer

The Garmin GST 43 is a thru-hull transducer that measures boat speed over water and water temperature. It provides boat speed and water temperature information to compatible Garmin gauges and chartplotters.

The transducer can be retrofitted to an existing Nexus TH43 43mm grommet, making it a practical option for replacing an old transducer or upgrading a system when the boat already has a compatible grommet.
