common practice in many PA deer camps is to leave rifles outside in the woodshed or similar...safe and secure of course...
just for the temp change reason..80 degree camp to 20 degrees outside your going to have issues....
even when im home i leave my rifle safely in the unheated garage when its rifle season.
No. It works the same way defroster in your car does....
The warm glass evaporates what moisture is on the glass, and doesn't attract moisture (fog) to the glass. Bringing a scope from warm to cold wont bother it, cold to warm, and you'll fog up.
I beg to differ on that one... I used to go out for PT without my glasses because they would fog up when I'd get outside. Fort Leonardwood is cold as hell ecspecially in the morning, but when I started running it would get worse. Then finally about 30mins into a PT session they would un-fog. So I think it depends entirely on the type of lens...
If it's going from cold to heat, it will fog... I don't care who made the glass or the scope... Put any two scopes "side by side" in the same conditions at the "same time", and you will get the same results!
