Do you have any idea of how many people own but have no clue how to use a lensatic compass. triangulation can get you out of a jamb, but only if you can identify some surroundings on the map. It basically is used to tell you where you are when otherwise you have no clue.
Lets be honest, alot of people will walk into the problem before consulting the compass or map so, learning triangulate would be high on the list as far as Im concerned. Its not going to do much good without a map and most will not have that either however, it seems nearly everyone carries the compass. Even when they dont know how to use it.
I would say that understanding the lunar fields would help most. Sun, moon, stars and so on will pretty much get you where you need to go to get out of a problem, it also helps to have that compass as it works well with the lunar fields. They never lie, but sometimes hide......
Heres a link to help with some navigation skills.

I hope this will help someone or at least make them aware a bit more. Its always funny to me to here about GPS systems. I have been lost..... the animals dont sell batteries and the trees dont unblock the signals when you get mad at them. Lost for a day is no big deal. Lost for a week test your ability to reason in my opinion.
Good Luck & Happy Shooting !
