well, like I said, I've never used a lumi zone or know exactly how they're put together but I'veseen enough pictures of them to form a decent opinion on how they're built and they appear to bebuilt somewhat well and for $150 youd think it would be a fairly decent scope

scopes only fog after bring them into warmer, morehumid air, taking them outside doesnt cause fogging(or any other problems for that matter), any sealed scope worth owning is more than capable of going through, and well below, the temp range your worried about, in fact thats exactly why they're built the way they are... to withstand extreme temperatures and changes in temerature from one extreme to the other, any decent low-end sealed scope should be able to withstand temeratures well below what you yourself is willing to be out in and then just as easily be able to handle being brought backinside without any trouble at all



alot of scopes that are battery powered will probably have a different operating temperature range than one that isntbut mainly thats only because of the battery, not the actualsealed tube of the scope

but then again I've had cheap reddot scopesout in well below0deg temps and never once had a problem with internal fogging on any of them after bring them in the house, the batteries get sluggish and the dot can get weak, but I've never had one fog...




like I said, if its sealed(and I'm sure it is) I wouldnt be worried a bit about takingthat lumi zoneout in 10deg weather and then bringing it back into the house, if that scope cant handle that mild of a swing in temperature range then my opinion of its qualityjust went to absolutely nothing and its a piece of junk youd never seeon anything that I own, andin thatcase youd be far better off getting rid of it and getting somethingelse...


in my opinion anyway...
