The SkyCaddie, developed by SkyGolf, is used on over 14,000 golf courses in 45 countries around the world. Weighing less than 5 ounces, the SkyCaddie utilizes the same global positioning system used by the U.S. military, but in a high portable handheld device, about the size of a cell phone, to compute distances to any point on a golf course. SkyGolf uses professional, high-performance GPS engines, satellite-based accuracy augmentation, plus proprietary accuracy enhancements to provide golfers with the distances needed to play smarter, faster and have more fun!
