While using your GPS as your primary direction finding "tool", you might want to bring an "old fashioned" good quality compass and topo maps along, too.
I totally agree. If a person has a good compass, you can shoot an azimuth or use cardinal directions to get you headed in the right direction. And I also agree with the use of printed topo maps. The gps should be a supplement to actual navigation skills, not your only source of guidance.
