Conclusion: I can't add much more than the description. This GPS works as advertised you won't be disappointed. The best part is the lifetime subscription! The weirdest feature is that it will record your position on each hole at regular intervals like 10 seconds (adjustable). When you get back to the PC you can see where you drove the cart (or walked) down the fairway, on the green, etc. It's pretty amusing to see how much you walk all over the green.
Conclusion: My wife got me a B/W GolfBuddy for Christmas but after some research, we decided to go for the full color Sonnocaddie. I've used it twice on familiar courses. The yardage is accurate but some of the known hazards were not illustrated. The beauty of this is that I can edit the existing hazards on the course. Probably the same for all GPS systems. The screen is easy to see. I only wish it would track the yardage of each drive and the distance of my first putts.
Conclusion: I have used in CO and taken to GA. I have about 15 courses loaded and downloading was easy. One membership fee and you have access to 20,000 courses+. I love the score keeper and distance button! The only drawback I have is it doesn't analyze the back nine only rounds. Easy to use and accurate within 3 yd. I have compared against sky caddies and it is equal or better. This really has improved my game because I'm not second guessing the club selection.
