A golf putting training device comprised of a cap with light emittor adapted to project a spot beam of light to a first position before a golfer putts, said spot to be observed by the golfer immediately after putting to see if the spot beam is in a second position, the distance between the first and second position indicating improper movement of the head of the golfer during putting.
