A golfing aid 21 comprises a hollow elongate member 2 containing a light unit 6. In operation the light unit delivers a beam of light in opposite directions through the either end of the elongate member 7, 8. The golfing aid may be a golf club and the elongate member may be the shaft of the golf club. The beams of light may be produced by two oppositely directed lasers each mounted to the golf club. The user may observe the paths of the beam of light to assess his performance. An audible signal may also be provided, indicating that the club has moved off the required path. |
