Callaway uPro

Think of golf range finders and GPS devices like good caddies, providing accurate distance measurements on blind shots and unfamiliar courses. That makes the compact uPro the Tiger Woods of caddies, adding satellite-photography-based course maps to give players a photorealistic flyover view of each hole—and a real competitive advantage. It also displays high-resolution pictures of sand traps, water hazards and other elements on its large screen, offering a precise virtual view of just about any shot on the course. With a database of more than 18,000 courses across the U.S., the only thing it can’t do is carry your bag.
