Introducing EGOS, the Expert Greenreading Operating System — a math- and science-based approach to lowering your putts per round (PPR) and reading golf greens with precision. EGOS eliminates the bias and brainwashing present in the professional golfer's approach to putting and green reading. No more foot feeling or plumb bobbing, no more memorization or "working harder" than the field. EGOS is as simple as A = B = C. All math, all science, no guesswork. And millions of dollars in prize winnings. Andrew Walters, a civil engineer, surveyor and inventor with a patented and proven system for reading greens, demonstrates through mathematical and scientific analysis that EGOS eliminates the 10 putts per round (that's 40 per golf tournament!) that are missed due to poor green reads. In this comprehensive golf-training book, Walters provides detailed steps and explanations, complemented by dozens of photos and sketches, to help you revolutionize your golf game with EGOS. It also includes his two PPR guarantees. Because EGOS is based on gravity, geometry and surveying principles, Walters and his EGOS disciples no longer misread greens. The proof is on these pages and on the golf course. So grab your putter (soon to be your "Surveying Instrument") or a specially adapted P&SI-EGOS all-balanced putter and put EGOS to work on the green! From patent protection the EGOS advantage can last a decade for Pros. For amateurs the EGOS skill set lasts a lifetime, and how far you hit the ball matters not.
