Abstract: The golf swing training device has a foreshortened shaft, a grip mounted on the upper end of the shaft, a head mounted on the lower end of the shaft, a first laser module mounted in the grip end of the shaft for directing a laser beam upwardly from the grip in co-axial alignment with the central axis of the shaft, and a pair of laser modules mounted in the head of the training device for directing a pair of spaced parallel laser beams downwardly from the head in a diametrically opposed direction from the beam emanating from the grip. The two beams projecting from the head of the training device are disposed in a common plane with a downward extension of the central axis of the shaft such that a line drawn between the points of impact of the beams on the ground visually defines the footprint and thus the angular orientation of an imaginary club face. The laser carrying head is configured so that it can not be used to strike a golf ball.

Abstract: The Dual Ended Laser Swing Aid has the general shape of a golf club and consists of a grip, shaft and head. Two back-to-back axial laser modules pointing in linearly opposite directions emit an upward grip laser beam through a hole in the grip, and a downward head laser beam through a hole in the head. Both laser modules are powered by a 3 volt DC power supply located inside the grip end of the hollow shaft. This arrangement permits convenient DC battery replacement by unscrewing a grip knob at the grip end of the Dual Ended Laser Swing Aid. During a swing with the swing aid the golfer can observe the laser traces of the grip and head lasers in a systematic manner for golf swing improvement. The laser traces can also be recorded by a video camera to allow the golfer to analyse every facet of the swing.
