Nothing ends a hunt like having your Bino's fog up, about 7 years ago I purchaced a pair of Brunton Eterna 10X42 (I would call them mid range optics) .

Last day of muzzleload season out of the blue both tubes fogged up internally. These are supposed to have a life time warrenty, I have all the paperwork. I called the manufacture got a return authorization number.

Anyone have any experience with having the gas recharged? They claim two weeks turnaround, and that this rarely happens.

I may need to buy another pair of bino's for the late hunt, any cheap good glasses out there?
