The Garmin GST 43 thru-hull transducer is engineered to drop into an existing Nexus 43mm (TH43) thru-hull opening, measuring water speed and temperature without requiring a new hull penetration. Bundled with the GST 10 interface module, the combination feeds real-time speed and temperature data across an NMEA 2000® network to compatible Garmin chartplotters and instrument displays.

Specifications:

• Transducer type: thru-hull
• Measurements: water speed and water temperature
• Compatible retrofit: Nexus 43mm thru-hull transducer (TH43) installations
