An Introduction to Map & Compass Navigation

An properly calibrated altimeter is also an extremely useful tool…

^Yes.  It’s surprising how often you can find where you are knowing nothing but your general vicinity and your elevation.  Much faster and easier than triangulating when you only need rough precision.  I’ve never become addicted to a piece of gear faster than my first altimeter.

So, to be clear, where I live right now is -1 degree 26 minutes. So, when I adjust my compass, the orienteering arrow will be a little to the west of the index point (direction of travel/true North)?

That’s right, though it might be more accurate to say the orienting arrow will be a little to the west of North on the dial.  What you said is right if North on the dial is aligned with the index pointer.

I believe it’s all still there. I am able to access everything.

“[T]he few times I have hiked with a gps I have still relied on basic orienteering to locate my position.”

I use GaiaGPS all the time for planning and for backcountry navigation. But, as good as it is, it can’t give you the “big picture” in detail as good as a quad. In the field, I, too, think you need both.
