You want to know why hand-held GPS devices are golf's next revolution? Imagine having a yardage marker at your feet everywhere you (and your ball) go. No guessing, no pacing, no calculating. And because the USGA now allows distance-measuring devices to be used (and shared) under a local rule, it's no less a game-improvement purchase than a new high-MOI driver is.
Hand-held golf GPS technology makes the navigation screen in your car look like an Etch A Sketch. GPS devices for cars are designed to pinpoint locations within hundreds of yards. However, golf GPS models use at least four satellites 11,000 miles above the earth to calculate distances within a yard or two.
Still not impressed? Well, consider pace of play. When the 2007 LPGA Teaching and Club Professional National Championship provided each competitor with a SkyCaddie GPS unit from industry leader SkyGolf, all three rounds were completed in less than five hours for the first time in the 20-year history of the event. Oh, and scores were down, too.
