Ernie Els Tempotimer

The Tempotimer gives you longer, more accurate shots with every club in your bag! A Perfect Swing must consist of 3 absolutes: 1) Swing Plane: an oblique angle oriented with the angle formed between the ball and the stationary swing center. 2) Tempo: the speed of the swing. 3) Timing: the sequence of motion, the order in which things happen during the swing. "To Improve your distance, accuracy, strength, and consistency, nothing beats the Tempotimer."
