Abstract: An improved golf club swing training system is provided for assisting golfers to improve their golf swing. The golf swing training system includes a golf club including a traditional shaft, head and head face. Moreover, the training system includes a light source for producing a plane of light. Preferably, the light source uses a laser for producing the plane of light which forms a light line when striking the ground or other flat surface. In addition, the swing training system includes a practice mat. The practice mat includes a plurality of substantially straight mat lines which are positioned and aligned to identify proper golf swing position at various points through a golfer's swing. The golf swing training system includes the golfer repetitively practicing his golf swing so that the light source produces a light line which aligns with the mat lines so as to reinforce proper golf swing position.

Abstract: An improved club swing training device is provided for assisting persons, such as golfers to improve their golf swing. The training aid includes a power source, a light source such as a laser beam, a light deflector such as a mirror and a motor for rotating the light deflector. The light source, light deflector and motor are affixed to the proximal end of a club shaft. In operation, the light source strikes the light deflector which is rotated by the motor. The light deflector is angled relative to the axis of the light source's emitted beam so that upon the beam striking the light deflector, it is redirected in a second direction so as to form a fan of light as the motor rotates the light deflector. The swing training aid includes a scabbard for affixing the motor, light deflector and light source to the proximal end of a club and for positioning these components so as to position the fan of light so as to assist a person in seeing their club swing.

Abstract: An automatic timekeeping and accounting unit is provided which has particular utility for use by professional persons such as lawyers, accountants, and the like.
