The Garmin GTEMP10-TH is a thru-hull temperature sensor designed to deliver fast, accurate water temperature readings from your baitwell, livewell, or open water. It integrates directly into an NMEA 2000 network with true plug-and-play simplicity, and its smooth, flush-bottom profile minimizes turbulence at the hull penetration point. Built to handle the demands of saltwater use, this sensor supports custom device naming across multiple installation locations for quick, clear identification at the helm.
