I agree with you about the bubble issue, but sending it back to the compnay will get you a brad new one. The metal housings are actually being phased out, as is the tritium. Radiation is bad I guess. And military compasses dont have a global needle in them. The dry needle is good though, if you want it to last forever.

just my expirience,
