But unfamiliar areas where getting lost is a real possibility? No I don't want to abdicate full responsibility for my safety to a phone.
My comment wasnt particularly that paper backups werent the best option in some circumstances, it was more against the general smugness / gatekeeping nature thats fairly common in outdoors circles, and that really unless have to worry about it being cold enough to effect your battery, really a phone should be a better option for most people and the fact it cant be considered reliable is an indictment on this industry as most of the problems (cold batteries aside) are easily solved (offline, detailed maps, battery issues), the only problem is solving them doesnt sell ads
I've walked hundreds of miles in England and I've always carried a map with me but I've almost always used the OS app and the paper was mostly for planning and getting a bigger view.
I am suspicious of electronics. This just seems like a case where, given the easy backup, why not use it when it might matter.
this fact is not unique to digital maps.
(Ordnance survey maps are available for your phone)
Various functions including maps will die if your phone goes offline, your phone will chew through your battery even in situations where you really need it for one purpose, general purpose apps like google maps will work well enough until they put you to the top of a mountain without cell reception.
These are all fairly easily solvable UX problems, users with enough knowledge can solve them but that to me is still a failure of technology.
You do know most outdoor maps are laminated, right? The ones you'd take with you on such a journey anyway. A phone can break in a dozen different ways, or just simply run out of charge. Slightly harder with a paper map.
Also very easy to lose a map, the nice thing about phones is everyone else you are with is carrying one, less so with maps. The only real way you are going to get everyone in a groups phone breaking is if you are somewhere extremely cold.
The fact that a bit of paper easily destroyed by some water (not exactly unknown conditions for Scotland) is considered essential should be a source of embarassment for the tech industry, not smugness.
