Gray’s Golf putting guide will help you shave strokes off your score! The putting guide helps any golfer achieve a more consistent performance on the putting green, where the money is made! This Advanced regimen is modeled for high school to college level competitive golfers. 100 putts a day from 6 feet will begin the process of making more putts! Once you are consistently making 50% or more of your putts from the 6 foot range, you are ready to bring your putting stroke to competition!
