This Garmin GST 43 is a thru-hull transducer for measuring water speed and water temperature. In this version, the transducer is supplied as a bundle with GST 10, allowing the sensor to connect directly to a NMEA 2000 network. That makes this set suitable for installations where speed and temperature data need to be shown on a compatible Garmin chartplotter or instrument display.
The GST 43 is also suitable as a retrofit for an existing Nexus 43 mm thru-hull transducer (TH43). This makes it a practical option for replacing or upgrading existing installations without changing the hull opening. Garmin support also confirms that the GST 43 Thru-Hull Bundle (010-04284-00) is one of the sensors that can be used with the GST 10.
