Marker usage
I was playing golf with a friend who is a better golfer than me. He commented that i had improved a hundred percent from last year and he noticed I was lining up my putter to the ball and hole. He pulled out the softspike marker and said to use it to mark the ball and line the ball to the hole and use the other line to line up the putter. I did and it helped amazingly.
Much to my surprise I watched golf two days later and witnessed the pro using the same Technic. Good Product.
