Abstract: A training aid has a light beam generator (10) adjustably mounted to a universal joint fixture (14) which is in turn held by a support strip (18) in outwardly spaced relation away from a golfer's cap bill (36) with the assistance of a spring clip (20). In use, the generator (10) is adjusted to project a spot or beam onto the ground or a golf ball. On a golfer swinging a club at the light beam spot, any unwanted body or head movement is immediately indicated to the golfer by movement of the light beam spot. Preferably, the generator (10) is a laser beam generator.
