Well, I said I don't carry a spare compass, only one for me - I'm just not sure that I very often need a spare compass, one generally being good for me. I realize folks get separated from their compasses, ok - that's still not enough for me to suddenly carry two compasses instead of one. YMMV and all that - nothing to keep anyone else from carrying as many compasses as they can haul.
Maybe this makes my a hypocrite, but it occurred to me after JerryFountain's post that my aluminum match safe has a button compass embedded in its cap, so I have that at all times I suppose as a backup. Being a button type I have never used it to navigate around.
