You probably DON'T NEED a compass now.
You DO NEED to learn to use one NOW if you don't already have it mastered.
When you do need it, it's kinda late to learn it. Learning it will make all the rest of your navigating skills sharper.
If you've got it down pat already, don't worry about it.
If you aren't sure you know what you don't know, get out one of those maps you printed out. Sitting there at home look at those maps for something specific on there you want to see, a peak, a cliff, a possible spring or old building on public ground. A possible hot spot for game, and time you know where the water is, is a good spot to look for game.
Now pick where you are going to park and figure the best way to travel from vehicle to the stuff you want to see.
If there is no path how are you going to know the direction you are traveling? How far did you walk? Is this the ravine you want to walk up?
You may as well now get used to figuring out how to keep track of these things while you are in small, familiar areas.
The maps will have a scale = a mile is this long on the map but how long is it walking? A mile is little over 5000 feet, a step is probably a little less than three but call it three. 1666 steps is about a mile, 833 a half mile.
"How the heck do I get anything done and count all those steps?" Look at your watch when you start and see how long it takes to walk a 100 steps. Do that a few times and you will build the confidence to take a good guess how far you went in a set time. Clue, half as far walking off the path as walking down the road.
All this forces you to pay close attention to the surroundings you pass through. Pay close attention, you learn more and you get more out of every experience.
I've never been lost but I've sure walked the long way around to get home before.
