This simple method is Tour-proven and allows the golfer to see how to correctly align the face of the putter. Miss hits produce a muted sound and spongy feel, whereas centre hits produce a crisp sound and solid feel. The thud versus the click provides instant audible feedback. The sweet spot 360 will give the player the feedback of incorrect and correct so they can start to repeat the stroke that gives them the correct contact, helping them on their way to becoming a better and more accomplished putter.
