The Garmin GST 10 lets you pull water speed and temperature data from existing analog sensors and push it onto a modern NMEA 2000 network — no full rewire required. It converts legacy analog gauge signals into NMEA 2000 format and broadcasts them to compatible displays, including the Garmin GMI 10 multifunction instrument, making it a clean path to a glass helm on any boat already fitted with analog sensors.

Specifications:

• Converts analog water speed and temperature sensor signals to NMEA 2000 format
• Broadcasts converted data over NMEA 2000 protocol to compatible displays
• Compatible with the Garmin GMI 10 multifunction instrument display
• Allows integration of existing analog gauge systems into a digital helm without full rewiring
• Designed for straightforward installation and simple setup
