I read a post recently stating "Bring a compass and/or GPS". GPS devices are very nice and helpfull however they are electronic things that for reasons beyond your control may cese to work. Electronics are prone to failure. For example the electronics on your EFI engine or electronic transmission have a "Limp Home" mode that in the event of a failure will not leave your truck entirley usless. GPS recievers have no limp home mode. Please every one carry a compass and know how to use it. Carry paper maps covering your route. The gazater is a easy way to do this for the long streaches and for the off road portions 7.5 min maps are availavble for free down load at USGS.gov. and print onto 11 x 17 with realitivly good resolution. Untill Overland Navagator has a print feature that is. All these things can fit in a zip lock bag hidden away and hopefully never used. The way I see it a compass and the ability to use it are mandatory and the GPS serves to augment and ease the navagaiton tasks.

Moved from General to the Navigation forum.

Absolutely agreed Peter. And to add to that, carry a paper map and perform your own navigation even if you are following someone else. If the leader gets hurt, you need to know the fastest way out of there.

We did a Map and Compass Navigation class a couple of years ago. It was Part 1 of a 3 part series that I never finished teaching. I'm hoping to get to teaching it again this fall/winter/spring...making it more hands on this time.

Compasses have limited utility for vehicle based travel as you can't follow a bearing. They are useful for triangulating ones location.

The biggest piece of advice I have for people is to "get the big picture". Whether it is a map on a computer, on a GPS, or on paper, look at it carefully before you start driving. Memorize roughly where the trail is going to go... E.g.

It is going to follow this creek West, then pass 4 lakes on the South side, curve around the South side of Big Mountain, and fork to the north before arriving at shady creek. Then set boundaries....such as If I run into a logging road then I've gone too far, or if I see Super Big lake then I've gone too far. Boundaries work particularly well when hiking as you can remember that if you just walk "East" that you'll run into XYZ main road.

Once you've memorized where the route is going, check off each of the items as you pass them so you always know roughly where you are at. If you are the navigator then you can do this with the map in hand.

 One of the things I remember from my early days hiking/backpacking is to turn around periodically and look where you have come from. The trail, especially if you are making it and it is not previously traveled, is going to look very different when you are coming back.  Not really an issue if you are going in one forward direction toward a goal.
