My goal is to locate rock art sites on a map as I hike, so I will be able to find them again. With this app, I was able to stand at the site and mark its location precisely. It works perfectly. I still need to learn how to transfer the map data to another computer, but Im guessing this will also work well. Unfortunately, with all this capability, the app is a real power hog. They give you suggestions to preserve as much power as possible, but my solution was to forego the routing function by turning off the IPad between sites. It boots up quickly for recording my location, and then I turn it off,again until the next site.
