Abstract
Abstract A golf swing instructional aid is provided having a simulated golf ball mounted on one section of a two-sectioned support rod. The other rod section has a clamp for clamping the aid to a golf club shaft. The rod sections are disposed at an angle such that the simulated golf ball is disposed in a square impact position with respect to the club face, so that a user of the club during practice swings can see the correct position of the club face with respect to a golf ball at the moment of impact, visualize the flight path of the ball and thereby practice correct positioning of the user's hands and body with respect to the club and ball. Separate clamp arrangements are provided for golf woods and irons.
