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.
I agree. Regardless of scope brand, I do not water test my scopes for leaky seals. That is another thing that should be done at some stage of engineering or QC. As far as "What if your scope fogs up on you on an expensive or remote hunt"? In that case, I remove the scope, put it in my pack and within less than 2 minutes have those old useless, outdated, pre-zeroed iron sights installed and keep hunting. RJ
