Re: Optics cleaning?
I've never really cleaned them in the field, while I do hunt in very rough terrain in all kinds of weather, I find that my flip caps keep everything out. I only open them when I know I'm close, or something presents itself. And even then I do occasionally get some dust, or pine needles, or a couple snowflakes/raindrops in there, but it never seemed to be a problem when it came to seeing clearly through the scope.
I just bring em home and clean them after the trip.
