Abstract
Abstract Accuracy of flight of a golf ball struck by an otherwise conventional golf club is improved by providing a circle of precisely the diameter of a golf ball on the upper surface of the club head whereby when the club head is laid adjacent a ball prior to a swinging stroke the adjacent circular configurations of the circle and golf ball coact to establish a directional axis accurately related to the line of flight of the ball when struck by the club.
