Simon Caldwell said:So what do you do when you're in a whiteout and your GPS dies?
C'mon, be honest, how often has your GPS died in a whiteout? Okay, let's be
realistic, it could happen. As a dedicated 6 year user of GPS, how many
times has my GPS ever died? Okay, I'll be honest, it's died twice! Once
every three years! That's not a bad average!
Let's consider these in more detail...
1. Unexpected walk up Pen y Fan. I went out one day for a photo drive,
just to drive around the Beacons and take photos. No walk intended, no walk
planned, no walking gear. No batteries charged in advance. But when I got
to Storey Arms the weather was so clear that I just couldn't resist it. I
got out of the car and climbed Pen y Fan. No rucksack, no gear, no walking
boots, nothing (except for the camera of course). It was just a spur of the
moment thing and the weather was so stable I knew it wouldn't change (it was
only a short stroll anyway). My GPS batteries were flat before I even
started the walk, so I couldn't blame the GPS. Didn't need it anyway, even
if the weather had changed.
2. Moel y Dyniewyd, Snowdonia. I spent a few days in Snowdonia, knowing
full well in advance that I didn't have enough battery power to last the
whole trip. On the last day, there was little power left, so the final walk
was done without GPS, just occasionally turning it on to mark a waypoint.
This was not a fault of the GPS, it didn't let me down, and the walk didn't
rely on the GPS for navigation.
Quoted message said:It
sounds from what you've been saying like you won't know from the map
exactly where you are. And that is the source of your problems.
Whether you use a compass or a GPS, you should always know roughly
where you are on the map. And if bad weather is approaching, then you
should make sure you know *exactly* where you are.
I agree, you should always know where you are, and the GPS is bloody good at
telling you exactly that! And if bad weather is approaching, what you
should be checking is not just where you are, but that you have enough
battery power for the GPS. So long as you have, there should be no problem.
Quoted message said:Why would traditional navigation start from the assumption that you've
already failed and are lost? The point of navigation, traditional or
high tech, is not to get lost in the first place.
True, but having a GPS changes the position of the goal posts. With a GPS
you no longer need to know where you are, only where you need to go, and the
GPS will guide you there, even if you don't have a clue where you are to
begin with.
So is it really that bad not knowing exactly where you are, provided you
have a reliable means of getting to where you want to go? Even if you find
your way blocked by an impassable cliff or river, just take a detour and the
GPS will still point you the right way once you get past the obstacle.
