The SG3.5 is fully-featured and has a large screen that displays distances to the green from anywhere on the course, as well as all targets and hazards on each fairway in large numbers. The SG3.5 includes SkyGolfs patented IntelliGreen technology, enabling golfers to measure the full depth and shape of the green from any angle of approach, both on or off the fairway. Size wise the SG3.5 is right in the middle between the smaller SG2.5 and the slightly larger SG5.
