Simple, accurate and comprehensive. The only feature this lacks is a scorecard which to me is inconsequential. Distance accuracy is never more than +- 5 yds from any other GPS device or yardage marker in the course. Usual variance is 0-2 yds and whos to say which device/mark is the correct one. The zoom feature is awesome. The only performance knock is that clouds will slow down position lock time. Nature of the business. It consumes 25-40% of my iPhone 4s battery over 18 holes dependent upon amount of "zoom" I use.
Buy it.
UPDATE - the zoom feature doesnt provide yardage to any spot on the course anymore. Is this a result of iOS 7?? I miss that feature immensely.
