I am looking to buy a scope screen and am interested in masking. I know there are power masking systems from Carada and others, but they are several thousand dollars....nice no doubt, but pricey. I see that Seymour will build CIH panels for a few hundred bucks using a magnet system. Sure I'll have to put 'em up and take them down myself, but for a fraction of the cost, I think it's a great option for me. I'm looking at their non-AT screen (glacier white, I think it's called), but I am a bit concerned that I might need a bit higher gain screen considering my planned screen size. So....here's my question: are there other options out there for me? Do other companies offer a similarly priced manual masking system, but with a few more options for a higher gain screen?
