Often times we feel like we're improving our swing during a range session, but really we're just ingraining bad habits over and over again. At times it can feel like our swing is changing for the better, until we take a quick look at a video and nothing has changed.
The Alignment Disc with rods will provide you with a physical reference point for your swing path. You'll know exactly when you're making steps in the right direction. You can also use the Alignment Disc to work on fixing other issues such as early extension, swaying, and more.
