ABSTRACT:
A feedback device, for use by a golfer to indicate head movement during a backswing. The device has a base, a forward plate having a transparent portion with a printed horizontal line thereupon, and a parallel mirrored surface located behind the forward plate. A reflected horizontal line is selectively viewed through the transparent portion. When the device is viewed at a first viewing angle, only a single line is visible, such that the reflected horizontal line is blocked from the golfer's view by the printed horizontal line. When the device is viewed at a second viewing angle, both lines are visible. Accordingly vertical head movement during the backswing is immediately apparent to the golfer when both lines become visible during the backswing.
