Abstract: A light-weight sighting or aiming device for showing the line of the path of a golf ball to be impacted by a golf club has a base head adapted to be releasably secured to the shaft of the club at a selected distance above the club head, a rod projecting forwardly from the base head to be aligned parallel with the club head, a pointer selectively mounted at different positions along the length of the rod normal to the axis of the rod and threads on the rod to extend and retract the rod relative to the base head so that the pointer will be positioned over the sweet spot of the hitting face when the golfer addresses the ball. The component parts of the device are preferably light-weight plastics material with the base head having an end spaced for gripping the shaft and with the rod member frictionally threaded for a substantial distance in the base head member. The preferred rod has a plurality of transverse holes therethrough spaced along its length to selectively snugly receive the pointer.
