Finally fix your early release and tempo The Tempo Stick is a revolutionary swing trainer that uses instant audio feedback to perfect your tempo and eliminate early casting. When you achieve the ideal release point, you'll hear a satisfying "CLICK" at impact - no more guessing if your timing is right. How It Works The built-in sliding weight creates an audible click at the moment of peak swing speed. If you hear the click too early, you're casting. Too late? You're decelerating. Click at the bottom? Perfect release for maximum power.
