• Club head speed at impact to the ball.
• Club face angle at impact (number of degrees open or closed) in relation to path angle.
• Club head angle of approach (hitting the ball on the down or up-stroke).
• Swing path in degrees (i.e. from out to in, in - out etc).
• Ball position on club-face at impact (vertical and horizontal distance from sweet spot on club-face is captured).
• Effective club-face loft at impact. i.e. a 7 iron normally has 40° of loft, but when the club is held at anything other than 90° to the ball, the effective angle at impact will be changed. Also, the club-face angle and hitting the ball on the upward or downward stroke will effect the loft angle and thus the flight of the ball.
• Ball spin rates and directions are calculated from the captured club data at impact. Side (or horizontal) spin as well as top (or vertical) spin rates are calculated and summed to give a final spin rate and spin direction. The side spin causes the ball to curve left or right depending on the direction of spin and the positive top spin will give extra lift and distance. Negative top spin (caused by topping the ball) will, on the other hand, cause the ball to dive.
• Ball launch path angle.
• Ball launch velocity.

The ProTee Golf Simulator club swing analysis functions record all swings and ball trajectory flight data. Of particular interest to club fitters, the data can be viewed in table form allowing you to compare performance characteristics of swings and clubs.
