RE: Scope fogging up!!!
If the scope is conditioned to the temperature unless you breath directly onto it, it should not fog. I leave my gun outside when I stop at the truck for a snack or something, if moving location by vehicle I leave the heat off inside the truck to limit fogging of optics and always keep my flip up scope covers open so the lens surface is exposed to the air. Their are anti fog sprays but I am not sure if they would harm the coating or not, I'd email bushnell for some suggestions. When I play hockey I use lemon dish soap or spit on my visor which helps with fogging but I am not sure this would be a good practice with scopes or binos either.
Best of luck.
