The measure of success - distance adjusted for elevation. built in the legacy of our venerable PinSeeker® 1500, the new Pro 1600 is the world's only golf laser rangefinder to compensate for changes in elevation. Using a digital inclinometer, it determines distance based on the degree of elevation change. It doesn't just tell you how far - it tells you exactly how far to play it. So you'll never again question the range at the top of your swing. And nothing cuts strokes, and elimates the peak and valleys of your game, like confidence.
