husky, matt has partly covered what i mean by "user error" and i use this term to cover most of the objections (or as i prefer just plain excuses) to gps. the only thing a gps can do is not work - just as any other equipment can break/not work.
running out of batteries - put fresh ones in it. haven't got spare batteries?. make note to use more common sense and be grateful it wasn't your headtorch batteries didn't die in the dark.
run out of map - retrace your steps until you are back on the map - easy peasy to do - and make note to self to pay more attention and buy more maps
don't know how to do that - if you want to then learn how to do that if you think it's going to be useful
the screen freezes on the gps and the batteres are crap in the cold and i keep it in my pack lid - i don't know if that is user error or just plain feckwittedness.
yep. a gps is an expensive bit of kit - expensive being relative as to how much the toy sitting in your rucksack cost. i am at a loss to understand why people who buy a gps only use it to get a location fix without even learning to use the basic features which can get you out of all sorts of trouble. learn how to enter a goto point (waypoint), learn how trackback works and how to save a track at the very least.
just as a compass is a very handy gadget (and it IS just a gadget) for telling you which way is north we all know it has rather more uses than that and those uses we have to learn and adapt to our own preferences. you would probably find someone's insistence on pulling their gadget out of their pack only when they felt the need to know which way was north somewhat bewildering.
in conditions like a whiteout a gps is immensely superior to a map and compass (tells you where you are, can tell you where to go, how far it is and can guide you back the way you came with the press of a button and it doesn't care if it's day or night. and a mpping gps lets you do all that without even having to press another button or look at the paper map). in other situations the map and compass is a better bet. whether an individual feels that makes it essential is their own call.
you are quite correct that a gps is not a cheap acquistion, even a "cheap" one, but this is solely down to if you consider it to be "essential" or not. perhaps a bad analogy but how many times is an ice axe used in anger as a safety device, e.g. arresting a slide? another expensive piece of equipment but is it essential? is it more essential if you haven't got crampons or is the axe less essential if you have crampons? i don't need an answer to any of that but i use it to try to illustrate what we all think of as essential equipment or not. it all boils down to personal choice.
what would your opinion be of someone who buys an ice axe (gps) but doesn't know how to use it?
my basic default mode is people can wear and use and carry whatever they like, or not. if something doesn't work then i assume a valuable bit of experience will have been learnt and they won't repeat it next time - and becasue things went bad they will probably tell 20 other people not to do what they did.
waldo, i would say essential equipment is what you take with every trip otherwise why are you carrying it. i would also assume that you know how to use it. your essential equipment will be different to someone else's.
