ABSTRACT:
A golf club face impact alignment device includes a light emitting unit and a light sensing unit. The light emitting unit includes a first light emitting device, a second light emitting device, a power source and an emitting case. The first and second light emitting devices and the power source are retained in the emitting housing. The light emitting unit is attached to the club face of a golf club. The light sensing unit includes a first sensing unit, a second sensing unit and a base. The first and second sensing units are secured to the base. Each sensing unit preferably includes at least one photocell and a sensing case. The golf club is swung between the first and second sensing units. Light emitting from each end of the light emitting unit must be detected by the first and second light sensing units to activate an indication device.
