The starter pack is great for tracking chip shots next to the green and putts. Attach an Approach CT10 sensor to your wedges and putter. To keep up with additional clubs, use your watch’s (sold separately) AutoShot feature. It’s all in the wrist. Pair your sensors with your compatible Garmin golf watch. The lightweight and secure sensors easily attach to the end of a club’s grip. You won’t even know they’re there while you play.
