The SkyCaddie SGX is a great unit, accurate with no problems so far. I have had it over eight months. I would like to see a higher priority in terms of adding hole view and IntelliGreen Pro to every course, but I am sure this will come over time. Some of the innovative ideas that were in their TV commercials have yet to come to pass. I am pretty sure SkyCaddie wished they had never brought up the subject of "Smart Club" technology. All in all as I gain more confidence with it, I am relying on the SGX more and more and keeping the lazer in the bag.
Takes a little time to bring up course, but not really a problem.
