I've often wondered why Brunton can't just engineer a bubble into the Eclipse compasses on purpose and use that as some kind of leveling device - to help ensure that the compass is nearly level ... turning lemons into lemonaide.
Though I REALLY like the Brunton Eclipse 8099, lately I find myself more often bringing along the Brunton 15TDCL (the original mirrored compass by Silva of Sweden - though the newer model has a more rounded cover, which is nice).
