| Personally I don't trust anything running on batteries, a GPS can come in handy in many cases, but I wouldn't wander into unknown terrain without at least a map, and preferably a compass.
And in the same breath I may add that I wouldn't trust navigation officers who haven't been trained in the ancient arts of celestial navigation and dead reckoning farther than I can throw them...
Paper, pencils and a map could still be usefull when electric power fail.
And don't say that it can't happen, it has done before, it will do in the future. |
