A golf swing practice (1) device comprises a carrier member (2) which is removably attached to the shaft (41) of a golf club (40) and which is preferably attached to a lower portion of the hand grip (42) on the golf clu b (40). Two spaced apart light sources (3, 4) are mounted on the carrier (2) s o as to emit two discrete and parallel beams of light which extend in a direction towards the head of the club (40) and which lie in a plane which bisects a face of the club head and which is also substantially perpendicula r to the club face. In an additional embodiment, the carrier member (2) can al so be attached to a hole (15) in the hand grip (42) located at the proximal end of the golf club (40) so as to support at this end a third light source (16) 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.
