The Garmin GTEMP10-TH thru-hull temperature sensor delivers fast, precise water temperature data from your baitwell, livewell, or open water directly to your NMEA 2000 network. Its flush-bottom profile keeps hull penetration clean and turbulence-free, while rugged construction stands up to demanding saltwater conditions. Custom device naming lets you label each sensor by location, so identifying the right reading at the helm is instant and clear.
