The Ball of Steel is 5 times the weight of a normal golf ball. Learning to make a solid stroke with the heavy ball focuses all your attention on impact. Consist impact is the key to mastering any shot in golf. Without it, it does not matter how good your stroke is, you cannot precisely control the balls direction and distance.
The Ball of Steel will help you develop a compact, efficient stroke. Watch great putters and you will see this stroke. No deceleration, no jab, and no complex thinking. Simple stroke + better contact = fewer putts!
