A:AnswerWhen you pair the club sensor with a Garmin watch, it recognizes that you are swinging that club with the sensor. Then on your next swing, it calculates the distance from where you swing that club until you swung in the next club.
A:AnswerI imagine that it uses Bluetooth to connect to your Garmin watch. The tracking for me takes place on my watch based on where you swing that club to the point you swing your next club. The watch recognizes your shots. As for battery life I don’t know how long it will last but I do know they are replaceable.
