The Garmin Approach S40 GPS golf smartwatch with CT10 club tracking sensors offer precise automatic game tracking. The Approach S40 watch shows distances to the front, middle and back of the green, hazards and automatically records detected shot distances (lie and ball contact may affect shot tracking). It also lets you manually adjust to today’s pin position for accurate approach shots. Pair the watch with Approach CT10 club tracking sensors to automatically track every stroke, including locations, distances and club type. Data from each shot and club is collected so you can analyze stats used by professional golfers. The Stats show up on your watch after pulling the club from the bag. The Garmin Golf app can also be used with the watch for live scoring, automatic scorecard uploads and the ability to review all your stats in real time during play or after your round on your compatible smartphone.
