Summary: First off, I would recommend any hiking GPS system as a backup to a simply map and compass. That said, I want to clarify something about this particular model. This is a basic beginner's device to learn about Navigation, Waypoints, Trails, GeoCache and all the additional methods that go along with these. It also has a good "Best Fishing & Hunting Times for Current Location" menu as well as "Viewing Sunrise, Sunset Times" and "Lunar Information".
Summary: hard to configure if you are technologically challenged buggy software lack of detail in base map topo software imports a bitmap image into gps unit - pixelated! This was only useful on the first part of my road trip to the Grand Canyons. I didn't use any paper maps going there. But as you zoom in and out, you see more or less roads depending on the area. And then the unit froze! Customer service was fast but the unit is on its way to repair.
