Being one of nature's Luddites, I know that GPS is not for me and I simply would never trust it or (more honestly) myself to use one correctly. I'm still wrestling with mobile phones and hate the buggers who use them in wild places. Fair enough if you break a leg and need to phone for mountain rescue, but not when its football results, test scores and inane chatter about eveything and anything. I recently went on a centenary walk with over 100 walkers - bloody phones squarking, pinging and playing daft tumes throughout! Do GPS thingies make a noise too or are they blessedly silent?
I love maps and planning the journey on the map and retracing my wanderings afterwards are an essential part of the joy of walking. Dear old AW (Alfed Wainwright) was a superb mapman and draughtsman, but he seldom used a compass and I feel certain that GPS would have brought forth a wry smile, acid comment and perhaps a furious puff of his pipe.
