Swingyde is the ultimate golf swing training aid!

The vast majority of amateurs, and a great deal of professionals, have no inherent concept of whether their clubface is square at the top of the swing or not.Swingyde will provide you with the feedback necessary to hinge the wrists correctly and assure that the face is perfectly square throughout the swing. In addition, it will help maintain a 'preset' lag position on the downswing & into impact. Includes instructional DVD by Jim Flick.
