This golf cup reducer fits snugly inside the hole to make your practice cup smaller, and does not damage the green. Golf pros have long known the benefits of putting to a smaller practice target: many of them have used dimes on the green as they warmed up. The No 3 Putt Cup reducer has the added benefit of actually allowing you to hole putts, thereby experiencing the successful sound of the ball dropping into the hole.
The addition of the smaller inner ring make the hole even smaller, having the psychological effect of making a standard size hole seem much bigger than it actually is. This effect can be a very powerful confidence builder on those crucial two footers.
