The newest installment to the SkyCaddie GPS line is the SGX. This unit is mecca for those looking for reliability and convenience. The one thing that is catchy about this device is that you have to spend some money if you want to use all of the features. But once you get it going the features are completely worth it. Our favorite features is the screen whether you have good or bad whether it’s always shinning, no glare even when it’s sunny. The last thing you want is to have to squint to see what it’s telling you. The battery life lasts for a good amount of time as far as we could tell in testing no problems with it draining too fast. A good price as far as GPS units go. We suggest you go to GolfClubs.com and see what kind of deals they have going on for GPS units.
