The Garmin GFS10 Fuel Sensor adds real-time fuel tracking to your Garmin chartplotter, helping you optimize your boat’s fuel economy with precise flow data. It communicates with your display over Garmin CANet or NMEA 2000, delivering fuel insights directly where you navigate.
A standout feature is its fuel level sensing capability. When connected to an existing analog fuel gauge or resistive tank sensor, the GFS10 provides fuel level information alongside flow data, giving you a complete picture of your on-board fuel status.
