Improve your golf swing and get comprehensive yardage and hole information on up to 38,000 golf courses with the black and white Approach S6 from Garmin. This GPS-supported golf watch with 1" color touchscreen display features Garmin's proprietary swing metrics: SwingTempo and TempoTraining. Both of these metrics are intended to help you achieve the ideal golf swing, which is commonly held to be a 3-to-1 upswing-to-downswing ratio. SwingTempo measures what the current relationship between your upswing and downswing is, so you can fine-tune it as needed. TempoTraining uses a series of audible tones to help you synchronize your swing with the correct ratio, effectively training you to develop an ideal golf swing.
