Golf & Baseball's Training Partner for 25 Years: Easy-to-Use and Reliable Doppler Measures Swing Speed and Tempo

[Tempo is Everything] - Train Your Body to Swing Like a Pro. The Tempo Timer helps you practice and maintain tempo to your swing from start to finish. Tempo improves consistency in your swing when training for more speed. More speed equals more distance in your drives. [No Ball Needed] - Yes, you can use an actual golf ball but there's no need to hit an actual golf ball—use a wiffle ball, Birdie Ball, sponge ball or equivalent to simulate a real ball. Immediate feedback provides a basis for golfers to determine swing improvements [Speed Measurement] - Range of speed measurement from 40 MPH to over 200 MPH. Speed drives more distance. For every 1 mph gain an average of 1 to 2 yards distance is gained. [Works With Most Swing Speed Trainers] - Works with the Stack System, RypStick, SuperSpeed Stick and other popular swing trainers. Combine this with a trainer, clubs and irons to increase speed and get more yards. [Batteries Not Included] - Powered by 3 AA batteries (not included); ideal for both players and coaches/instructors. NOTE: Refer the Manual before use. [Made In USA] - Simple to use and easy to read using the same radar technology that defends our country with the Patriot Missile Defense System and reliable for over 20 years.
