I thought, I would deviate from equipment discussion here and discuss a training aid that has been out for a number of years that many great golf teachers have been using. It’s called The Impact Snap and was developed by Kelvin Miyahira of Hawaii. Kelvin developed this tool which will show the golfer how to correctly release the club. See video below.
This device (Impact Snap) is what I show players about the release. Supination, Flexion and Ulnar Deviation. These three facets are talked about in Homer Kelly’s The Golfing Machine. Helps maintain the Flying Wedge.
