Freezing a scope

It's a good way to test its waterproofness. Freeze it then set it out in a warm room. If it fogs inside, there are issues.
 
"I heard that a good way to test a scope is to freeze it and see if it fogs is this true what are some other ways to check to see if a scope is good?"

are you kidding us?

put it in the oven, microwave and blender? hit it with a sledge hammer, and then throw it out of your 3rd floor window on the concrete?

Were you expecting a more precise answer?
 
nightforce, does that and a lot more to each and every scope they sell. If it can't take a freezing then its no good for a Canadian hunt that's for sure.
 
You could put it in a padded vice, mark the wall, and do 50 clicks up,right,down,left to see if it returns.

I assume we are talking about testing before you mount the scope, so you can return it unused. If you put it in the blender, some people wouldn't take it back.
 
Immerse the scope in very hot water. If you see a stream of bubbles rising up, the scope is not sealed properly. I would recommend leaving the turret caps on if you try this.

Thanks for all of your wonderful insight ill get right on that lol.
 
I guess if you've just paid BIG bucks for a scope that claims to be all singing and all dancing ... why then you should expect it to survive some rigorous testing.

But for most of us I dont think it is that necessary. Even great scopes after several years will lose some of their integrity and fog under tough conditions particularly when age has dried the sealing "O" rings etc.

I have scopes with no nitrogen and lots of places where water could penetrate if held under 10 feet of hot water for 15 minutes. But I dont hunt in those conditions and if I am just sitting or walking in the rain I am always able to keep the scope and action at least partially protected. Probably the worse situation I encounter for a scope is moving from a very cold environment to a warm humid environment which invariably will cause external (and possibly) internal moisture to gather. In those situations I leave the scope AND rifle out in the cold till the next days hunt.
 
I wouldn't own a scope that couldn't pass the freeze test. Internal fogging is one of the worst thing that can happen on a hunt. It's really not much to ask of a scope...even sans the singing and dancing. My scope is often exposed to the elements for days at a time....the least it can do is not leak or fog up. It's really not much to ask.

"what are some other ways to check to see if a scope is good?"
Oh yeah, else than putting it in a freezer? maybe read reviews or look through it?

Define good? What is your scope, what is your budget, what do you need on a scope, what is good or bad for you.
With a vague question like this on scopes, "what are some other ways to check to see if a scope is good?"

Kmon, you can't blame me for trying.
 
There is a dishwasher test pioneered on CGN, the results of which if posted here would attract many comments and suggestions.
 
freezing a scope and bringing it into a warm room is a good test. But I leave my scopes attached to my rifles once I start a hunt. and I wouldn't bring my rifle into a warm room under the same circumstances. Anyway I understand the science .... just not an issue for me
