Wow. Great timing for the compass question. To answer your question before I possibly hijack this thread, a bubble will not harm the integrity of your compass. Bruntons are notorious for bubbles and I researched it pretty hard online.

-------------------------

Thinking of swapping out the Silva Ranger I EDC for something lighter and smaller, like my Brunton 8096 Adventure Racing compass or actually was thinking of buying the Suunto A-10. I'll continue to back up with a micro dry button.

The 8096 and A-10 are both lighter (25% & 50% respectively) but the Ranger has a mirror which is my back up to the 2oz signal mirror i carry.

Not stuck on any one make/model. This is not a choice of a primary for the back country, just an around town, city travel compass.

Suggestions or thoughts?
