Using a powerful microprocessor, GPS, and satellite-based accuracy enhancement technology, the SkyCaddie automatically calculates, as you move, distances to up to forty targets per hole simultaneously in less than a second. You will already have your number when you get to your ball.
Excellent product. Very cool & easy to download courses to the unit. Really helpful for a scramble or when visiting a new course. No question it's a big advantage to the player or team that has one on their team.
