Summary: This is NOT what it is advertised to be. You get hooked into buying yearly subscriptions and when I downloaded the courses I play here in Minnesota, it didn't have the layout of the course. Only an approximate of where I stood, and where the flag was.
Conclusion: I recently purchased the SkyCaddie SGX GPS device. I have owned 2 Sky Caddies before, the SG4, and the SG5 and now the SGX. I have used it 5 times now, purchased the top tier membership plan. I am not overly pleased with the SGX.

Summary: I chose this after having used a phone based application for about a year as I felt that a dedicated device would be faster, more accurate, and provide a better interface - surely the case for something designed specifically for the task. How wrong could I be? Completely.
