I've been prompted to do the figure eight thing a couple of times, but most of the time the compass does work for me. So unless you live in Greenland or wherever magnetic north has drifted to this week, you might take the thing in to check. > On the other hand, who needs it?

I have found that I rarely use the compass (which I find more reliable than the GPS which I would like to use). But I could see finding it useful if you are out in the woods when it's overcast. And I'm sure that there are plenty of uses that I haven't considered. -j -- Jeffrey Goldberg http://goldmark.org/jeff/ I rarely read HTML or poorly quoting posts Reply-To address is valid

Once I was in a group of six people skiing across the Hardangervidda icecap in a whiteout. About once an hour someone would briefly turn on a GPS and work out our desired heading. The person at the front would look at a compass and set off in that direction but within less than a minute they could easily get 90 degrees off course without realising it (the person behind would have to shout to tell them they were actually going in a circle). There were no visible landmarks whatsoever and in that situation you actually need a compass board to hold the compass out in front of you so that can easily see it at all times in order to maintain anything like a straight line. Before the advent of GPS the essentials for wilderness navigation were map *and* compass, with an altimeter (barometric) being a useful addition in high mountains (provided you remember to reset it every time you reach a point with a known altitude).

In the extremely rare situation where neither map nor sun can tell me direction, my strategy is just go downhill until I find water, then go downstream till I find people.
