External sensor for temperature measurement in conjunction with GPS.
Warm or cold, plus or minus degrees? No more questions with the ANT+ temperature sensor from Garmin. This small external sensor can be attached to jackets, shoes, backpacks and more and then sends the temperature data to your compatible Garmin device. This turns the Fenix wristwatch into a useful thermometer. Various Garmin GPS devices can also display the data. So you can always keep a close eye on the temperature.
