Garmin GTEMP10-TH Thru-hull Temperature Sensor

Fishermen, both freshwater and saltwater, need to keep accurate
tabs on the temperatures in their baitwells, livewells and the
waters they are fishing. The GTEMP10-TH is the perfect solution.
This high-sensitivity, fast response thru-hull temperature sensor
provides NMEA 2000 data with the ability to name each device
location, such as livewell port or baitwell starboard, when used in
multiple installations. It has a robust mechanical design that is
easy to install, and it’s built to last even in harsh saltwater
environments. Smooth, flush bottom design decreases turbulence in
thru-hull installations. Connects easily with simple plug-and-play
integration to your NMEA 2000 network.
