That would still not give rural players enough pokeballs to catch what they can find . <| sep |> Maps are always the wild card as already mentioned . Loading free maps onto a dedicated unit may take a bit of fiddling , and the ones available for purchase may not have all the details you want . The screens are also too small to show proper context , so I generally only use a dedicated unit if I expect to record tracks for a number of hours . For navigational purposes I just use my iPhone , as it has both GPS chip and barometric sensor . The interface is also better , so I can easily zoom and scroll maps , although I usually just use a paper map with it instead . Keep in mind that for travel or being out in the country , it ' s a good idea to keep the phone in airplane mode and download maps ahead of time , either back home or using a hotel ' s wifi . That way you avoid both roaming charges and running down the battery .
