I use my Ipad Air II along with Google Maps and other mapping apps to find my way into remote locations all the time. I've also used my 7" Asus tablet the same way. You need to make sure that your maps of the area are available without a wireless or cellular connection, which means having a mapping ap that stores the maps on the tablet at the projection you need. Google Maps can do this ........you just need to go there on maps and save the maps you want. It's best to have a tablet with a cellular connection so you can get a satellite or terrain view if you need one by backing up the the nearest cellular connection. The app called You Need A Map among others stores it's maps on the device, but sometimes you want more. Spend the money for a 4G version. On my Ipad it was an extra $130 (well spent). You can do everything you want on an Android for less money just as well. Apple commands a premium price and doesn't really offer any advantage except for upgrades that are easy and work. This is my second Ipad, and I'm well satisfied except for two things. One is that car charging is marginal at best.... If you are using it pretty steadily in the car, you'd better have a power point that provides power when the car is off because you are going to lose ground. The system and the backlight draw more power than the car charger can supply. This is probably equally true of Android tablets. The other annoyance is the lack of any kind of file manager..........Though it is not really needed on IOS, but is essential in Android.
