One of the most critical aspects of the golf swing is the position of the head during the swing. Many professional golfers and instructors will tell you, keeping your head still during the swing is absolutely critical. Others say some lateral motion is normal. In any case, head motion is hard to detect during the swing. The Head Motion Indicator (HEMI) Rod enables you to see this motion very easily and accurately.
