    • That’s not a GPS device. It has a small RFID inside. It is used for timing purposes. You need to run or cycle over a certain carpet or near a censor to get it to register. All bigger events use this. Triatletes put it around their ankles, runners put it in their laces. No idea about other sports since I only do the 2 mentioned before.
