(But you could be without a Compass)
The wilderness traveler needs at least two (2) good Compasses.
A really good plotting Compass to do map work and shoot azimuths with and a quality back up.

I keep this one on my belt in an Military issue first aid dressing pouch.

A quick reference Compass or Combination thermometer is a handy addition to your Pack strap.

This inexpensive instrument has a wind chill graph on the reverse side so you can have something to read as you freeze to death.
