Abstract
A golf alignment marker system is disclosed wherein a calibrated grid is provided on a golf ball and a golf club face is provided with a marking surface whereby when the club strikes the ball, a mark is imparted to the ball surface at a specific location within the grid. The golfer may then correlate the marked spot with the ball flight. A reader is provided to assist in reading the exact marked spot and a chart provides an analysis of the deviation of the marked spot with the correct impact point. An alignment scope permits proper orientation of the calibrated grid when the ball is placed on a tee. The invention may also be embodied in a training device for an accurate determination of the club swing and club face orientation. The golf alignment marker system of the present invention economically assists the golfer in determining the exact three dimensional orientation of the club face at the moment the ball is struck.
