That reminds me, I need a new backup compass
I did have a Timex with an electric compass that fit this role but after one failure resulting in a warranty replacement and a subsequent catastrophic failure while wearing it in an office environment, I switched to a (hopefully) better watch without this feature.
I do have a pin-on globe style compass on my large pack which is kind of nice. Like
this, but an older model I think:
I keep it pinned to my shoulder strap and can glance down at it to verify my general direction of travel. I might just pick up another one of these for my day pack, although I guess it really won't be much help if I actually needed to follow a specific bearing.
Actually, I'm wondering if something like this would be a better idea:
Navigator Compass
