A golf swing practice device is disclosed and which comprises a carrier member which is removably attached to the shaft of a golf club and which is preferably attached to a lower portion of the hand grip on the golf club. Two spaced apart light sources are mounted on the carrier so as to emit two discrete and parallel beams of light which extend in a direction towards the head of the club and which lie in a plane which bisects a face of the club head and which is also substantially perpendicular to the club face. The light tracings on the ground from the two beams of light on the ground and relevant to a target line which is also on the ground, inform the golfer if the practice golf swing relative to an imaginary golf ball is on or off line, square to the ball or being hit in a toe-in or toe-out condition. In an additional embodiment, the carrier member can also be attached to a hole in the hand grip located at the proximal end of the golf club so as to support at this end a third light source the beam of which is coaxial with the shaft of the club and which extends in a direction opposite to the beam direction of the light sources on the carrier member. The ground tracing produced by this third beam can be used to inform a golfer of the swing plane of the club shaft.
