If some want to dunk their scopes in hot water so be it. Since that is something that is hard to imagine a scope being subjected to, I find little interest in doing so for the reason of why subject it to an extreme that may cause it to fail prematurely. Which in all likelihood would be at the wrong time. Leave them outside on a cold winter night then bring them in the house and see what happens seems to be more realistic of real world conditions. Let the manufacturer do the extreme testing in it's R/D department. Can't remember of hearing about a Leupold of recent manufacturer fogging. Even by the non Leupold people on this forum.
