No ,I don't keep a compass in my PSK , I usualy have one on my keychain. I just recieved a K&M matchcase in the mail today. It has one too. (really nice item, not to change the subject <img src="/images/graemlins/grin.gif" alt="" />) I now have a back up compass.
I played around with this magnetic tape all afternoon (my one day off this week <img src="/images/graemlins/grin.gif" alt="" />) I surprised how well it's working. i dropped my caes a few times from different heights and nothing fell off. You open up the case and all the do dads are held firm to the magnet. not a bad set up if i say so myself
