Re: Handheld gps
I doubt if a GPS will have maps on it, the normal GPS shows the co-ordinates and you read a map to see where you are, allow for the magnetic variation otherwise you will be miles off course.
A sat nav system has maps loaded on so you can see where you are but they need updating for motor car navigation but not very often.
GPS for walking over hills and dales don't have roads or footpaths on but if you keep a record of your co-ordinates every mile or so you can retrace your steps if you get lost.
Another point to remember is that even if you know the co-ordinates of a place you want to visit and enter it into a GPS it will only point you in a straight line to it so you must enter waypoints around lakes and streams etc. They are not toys.
I spent many hours at Fleetwood nautical college before I got brave enough to use one at sea, I know it's a bit different but if you are on top of Pendle in a thick mist the results are the same.
Take care.
