Considerations for a Foot Passenger GHB.

[SlyUrbanFox]

I have the same apps on the tablet and phone. If bought through Google Play, they sync between devices so the new map app on the tablet magically appears on the phone. Make sure you download the maps for offline use in case the network is down. GPS should be fine unless EMP has taken it out in which case phone/tablet won't work anyway. I prefer the tablet for maps as my eyesight isn't getting any better and the phones too small.
The tablet has tube and bus maps/timetables, British waterways map, supermarket finder(surprisingly useful) sunrise/sunset app. Google Maps will let you set your own maps with useful points like water/cache points.
