Get tour-level distances and pinpoint accuracy with the Blue Tees S3 Max Rangefinder. The S3 Max features slope adjusted yardages, which removes any guesses in regards to increased and decreased yardages due to elevation changes. The slope feature can be disabled, making this a tournament legal rangefinder. Pulse Vibration and Flag Lock technology ensure that you've locked onto the target and with 7x magnification, you're able precise distances at an astonishing 900 yard range. While many rangefinders' displays are difficult to read in changing light conditions, the S3's Auto Ambient Display senses the amount of light present, and switches between black and red text to significantly improve visibility.
