Ive hike for many years. I found this the best thing since sliced bread. I downloaded several of the ny/nj trail conferences maps. They were very clearly displayed and easy to follow. The gps traced exactly the hike in took. It allow me to measure distances from point to point. The apps allows me to zoom in on the map, much easier to read than the paper maps. I would suggest getting a battery case or external battery to prolong the phones battery. I could easily hike for several days with the extra batteries. Looking forward to do overnight hikes.
