SkyGolf's unmatched reliability and accuracy is created by walking the golf course just like a PGA Tour caddie would, recording any and all critical data necessary. As a result, golfers are able to utilize over 30,000 professionally mapped courses and measure the distance to the green from any angle of approach along with all hazards. The patented IntelliGreen technology within the SkyCaddie rangefinder allows golfers to measure the shape and full depth of any green from any angle on or off the fairway. Its sleek and ultra-compact design makes it extremely durable and water resistant for play in all types of weather conditions.
