DougR replied to JohnBarry's topic in Training Aids, GPS Devices, Apps, Accessories & More!I have used it for almost a year. I really like it. The battery on my iphone lasts 18 holes no problem, but I think it would not last 36..... Have played quite a few different courses with it, so far it seems to have them all. Accuracy is what you would expect. GPS is good, not quite as accurate as laser rangefinder if the target is visible. I also have Golfplan and Golfplan syncs with Golfshot. Golfplan had a problem when iOS was updated, but tech support has fixed it now. I dont use the Golfscape feature, I tried it once and it was buggy.
