A Tour caddie paces every hole, and every green, to get accurate yardages - and so should you. ONLY SkyCaddie® mappers walk every golf course using survey-grade GPS backpacks, marking up to 40 critical targets for each hole - including contours, distances to hazards, fairway targets and layups which may be invisible to laser rangefinders. Don't rely on old aerial photographs - trust SkyCaddie to give you the most reliable information in the game
