You spend most the time on the golf green reading the line from your golf ball to the hole, and what good is that if you don't make the putt. not because you read the line wrong but because you mis hit the ball off center. Using a line on your golf ball not only helps you set up and read the line but it lets you know if you hit it correctly. If you mis hit the ball off center of the club face, the line on the ball will wiggle instead of rolling straight along the line. This will cause the ball to roll off center and mis the hole. Without the line on the golf ball you cannot tell if you mis read the putt or if you mis hit the putt. If you have hit the ball correctly and in the center of the club face the ball will roll smoothly along that line towards the hole, you can now tell that you hit the ball correctly. If you do this and still miss the putt then you read the green wrong. Using Red Arrow Markers will help you determine this, even if the average golfers does not understand, and thats ok. The golfer will still be able to see the line wobble and know right away he may miss the putt because he did not hit it correctly just by watching the line on the golf ball. Among helping you read the line, set up your put and putter, but actually help you putt better is why you should choose Red Arrow Markers as your new favorite marker.
