A rotatable horizontal sighting ring at the upper end of a vertical support post has a ball/club path marker extending thereacross and outwardly therefrom and a clubhead alignment marker extending transversly across the sight ring to form a cross hair sight at the center of the ring. A smaller ball sight ring approximately the same diameter as a golf ball is disposed within the larger sighting ring at one side of the clubhead alignment marker. In use, the larger sighting ring is positioned such that when viewed by a golfer in a standing position, the smaller ball sight ring is superposed over the golf ball and the ball/club path marker is aligned with the desired ball path and the clubhead alignment marker will be perpendicular to the desired golf ball path. A lower ball alignment member may also be installed on the lower end of the post vertically below the sighting ring or used separately. The lower ball alignment member has lower clubhead alignment marker extending outwardly from the post, an arcuate ball receptacle at one side of the lower clubhead alignment marker, and a lower ball/club path marker extending rearwardly from the arcuate receptacle at a right angle to the lower clubhead alignment marker. The lower ball alignment member is positioned with its ball/club path marker forming an extension of the desired ball path and the cross hair sight of the upper sight ring is positioned such that the upper and lower ball/club path markers and upper and lower clubhead alignment markers are superposed.
