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 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: I got mine about a year ago, I was very impressed at first. I liked all the features, score card, instant yardages, analysis, adding features.. After a year you would expect improvements to the software but none have been done, also expected them to make revisions to courses by adding missing hazards, or correct errors on existing layouts, but nothing.
Conclusion: I've had my Sonocaddie for some three years now. At first I thought this was a great unit because of the features but after using it I think that the accuracy is somewhat undesirable. The yardages can be off by 20 yards at time. I have the nikon laser range finder and it is far more accurate than this gps unit. The features are pretty good.
Conclusion: I have had mine for a couple of years now. The problem I have it that it is not always accurate. It can be 10-20 yards off sometimes and that it can vary from one hole to be next. Sometimes I had to wait 10-15 seconds for it to adjust to the new location. Also, for many courses, not many yardages for many hazards, bunkers, trees, etc are even given. I get nothing like the display shown in the ads. Sometimes I have to use a laser range finder to give me such yardages.
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.
