SkyGolf SG3.5 The SkyGolf SG3.5 offers the perfect mid-range unit in the SkyCaddie golf GPS unit line. The large, easy-to-read, color screen clearly displays distances to the green from anywhere on the course while SkyGolf ’s patented IntelliGreen technology enables golfers to measure the full depth and shape of the green from any angle. Its durable construction and AAA battery power make it easy to use on the course without complicated cables. In a size slightly larger than the SG2.5 and slightly smaller than the SG5, the SG3.5 is big enough for a comfortable feel in your hand and small enough to slide easily into a pants pocket or golf bag pocket.
