Use S6 to train your swing with swing metrics, featuring SwingTempo and TempoTraining. SwingTempo measures the relationship between upswing and downswing and expresses it as a ratio. In studies of successful golf swings, an ideal ratio of 3:1 has emerged, even with individual variations of speed. TempoTraining uses the 3:1 ratio and gives you audible tones to synchronize your swing mechanics and fine-tune swing tempo. Which makes S6 as valuable on the driving range as it is on the course. Never miss another text, email or alert just because your smartphone is deep in your bag. S6 acts as a wireless extension of your iPad or iPhone 4s or later, displaying whatever your device does, right on your watch. Now you can read that email or text you’ve been waiting for, via Bluetooth, even in the middle of the fairway.
