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. The device only weighs about 1/2 ounce and requires no alteration of the club so that it will have no effect on the feel of the club.
An indicator for detachably mounting on a shaft of a golf club to show the line of travel of a golf ball to be impacted by the sweet spot area of the hitting face of the club and deviation in tilt of this hitting face relative to the ground which comprises a base head having means for detachably mounting on a golf club shaft, a rod projecting axially forward from said head, a pin selectively mounted at intervals along the length of the rod to project normal to the rod and extend fore and aft of the rod to provide a sighting line extending on both sides of said rod, means for retracting the rod into and out of the head to finely adjust the position of the pin for overlying the sweet spot of the putting face, and said rod and pin being free from any visual obstruction other than the pin and rod themselves.
A light-weight practice device for attachment to the shaft of a golf club having a shaft and a head with a sweet spot for impacting a golf ball without changing the feel of the club which comprises a base having means for detachably mounting on the club shaft to extend forwardly from the shaft, a rigid rod threaded into the base to a selected depth, said base being positioned on the shaft to carry the rod in overlying parallel relation with the head of the club in spaced relation above the head, said rod having a plurality of transverse holes spaced along the length thereof, an elongated direction indicator pin selectively and directly snugly fitted and gripped in a hole of the rod at right angles to the rod axis to intersect a sight line between the sweet spot of the head and the eyes of a golfer addressing the club to a ball, said indicator pin being substantially longer than the rod and having substantially equal lengths extending fore and aft of the rod, and the threaded connection of the rod with the base accommodating longitudinal shifting of the rod to position the pin directly on the sight line.
