Vince to be exact I got 9 extra minutes of target visibility with the Conquest over a Vari X lll so you got that one dead on.

JD,I tried taking my scopes out of a warm house(70 degrees) into -14 degrees out in the woodshed to see if any would fog.All scopes(Bushnell,Leupold,Redfield,and Conquest)all passed with flying colors.I think if your scope hasn' t degassed it will preform fine in the cold with no internal fogging.On the outside from breath or body heat at this point the Bushnell with rainguard seems to be the only one able to conquer this(several other scope manufactures are working on their own lens coating as we speak).
