Abstract: A device to aid golfers in perfecting their golf swing during putting, chipping, driving and other usual golf situations. It provides a swing track comprising a pair of parallel spaced rails, rotatably mounted to a bracket, so as to be offset from the base surface. This track defines the preferred swing trajectory in the vicinity of ball contact. Faulty swings outside of such trajectory will touch one of the rails, imparting motion to the track. This rotation of the track both indicates the faulty swing and suggests the correction needed.
