The driving philosophy behind the Optimal Tee is that teeing your ball, so the equator (1/2 of the ball) is even with, or just above, the top of your clubhead provides you the optimal conditions for the most distance out of your drive. Teeing the ball in this manner promotes higher launch and lower spin, consequently increasing distance off the tee.
Optimal Tee uses USGA specifications to create a patented formula used in the design of each tee. This provides you with the best options for teeing your ball, so it is at the perfect height every time.
Professionals agree this is the best height for teeing your ball.
