There is also a golf swing tempo training product called CoreTempo which consists of three sets of MP3 files (Senior, Mid, and Pro). Each set consists of 72 MP3 files covering 6 tempos and 12 Swing Ratios. Swing Ratio is the backswing timing divided by the downswing to impact timing and ranges from 2.1 to 3.2 for most PGA Tour Pros. Each set is $19.95. Instead of beeps or vibrations marking events in the golf swing, CoreTempo provides continuous audio feedback and is based on a model of a perfect golf swing. For putting tempo training, Puttronome MP3 tones guide you to a perfect pendulum putting stroke. Consistent tempo is critical to good putting distance control and Puttronome MP3 files can definitely improve your stroke.
