Known devices for indicating such head movement are difficult to interpret due to the absence of any readily detectable correlation between what the golfer sees and the particular head movement error occurring. The present device comprises a base 6 having a support member 5 supporting a sighting means 4 above a golf ball address position and between such position and the head 23 of a golfer 1. The sighting means comprises spaced apart proximal and distal sighting elements 17, 16 having respective framing elements 18, 19 defining similarly shaped sighting apertures 20 dimensioned so that the proximal sighting aperture subtends a larger angle to the golfer's eye, in use of the device, than does the distal aperture. The framing surface 19 of the element 16 has a visually contrasting appearance to that of the proximal framing surface 18 whereby head movement of the golfer 1 during swing is indicated by a change in the size and/or shape of the distal surface 19 as viewed by the golfer through the proximal aperture 20. <IMAGE> |
