Andy Walters is a life long golf enthusiast and a 30 year Professional Civil Engineer and Land Surveyor. Like most golfers he often found himself mis-reading putts due to optical illusions. Because of his background he set out to solve this problem as he would any other engineering project and he did. Andy created a patented putter and a patent pending system for reading greens, called EGOS. The EGOS method allows a golfer to have a True Vertical which is mathematically and scientifically proven to work as the best way to read a putting green. Andy has been published in Golf Tips Magazine and is the go to guy for using a True Vertical to help others become expert green-readers. He often works with golf coaches, instructors, amateurs and up and coming pros.
