After reviewing the previous post about Urban Survival Kits I realized that I do indeed need a small compass and signal mirror. I have no problem getting around Chicago since I grew up there put this past weeks adventure in Houston helped me realize the benefits of having a compass in an urban environment that is not so familar. <br><br>Question that I have is where do I find these Brunton 15mm button compasses? I've seen references to popping out the compass in a Coleman combo thermometer. Is it hard to pop the compass out without damaging the compass? Is this compass really the Brunton 15mm or is there a place that I can actually buy a geniune brunton 15mm compass. Second, where do I find a decent signal mirror that will fit in my altoids box. Any ideas? Thanks for the help.
