Actually Cabelas and Bass pro have dimly lit places to evaluate optics. Ever notice the shooting gallery on the other side of the store? They didn't do it on purpose but I was able to evaluate several top shelf optics peering into the dimly lit shooting range. Look for fine details in the back wall, with the naked eye I couldn't see the rocks but with the bino's I settled on I could see the fine cracks and detail. I drove the guy at the optics counter nuts for months, after all good glass IS pretty salty.
