Hi All
I am an old hand with Map and compass and a new hand with a GPS. My primary tools on the hill are the map and compass, but I find the GPS useful as a cross reference tool.
My current tramping ground is Dartmoor where navigation can be "challenging" as it can been seen as a series of long round ridges and when the visability gets down to 5 meters you need all the help you can get
I find the greatest use of a GPS is the data it gathers. I can clip it onto the rucksac and it logs the walk (or in the case of last Sunday logs the walk for 8 hours then the batteries give up due to the cold
) When I get home I can take a good look at the walk on the map. I've just started using QUO and still getting to grips with the user interface.
All in all the GPS has its place, but you need the basic navigation skills to use it.
