I think it is a chrome electroplated on stainless steel. Around irregular surfaces/holes the electroplating is sometimes variable. Perhaps the electroplated chrome is too thin around the hole.sounds about right, it definitely looks like a chrome finish, but i don't see it being stainless steel. No matter how much you polish it you cant revive the surface once the finish starts flaking off
I like my Ascent Packrat case for my IQ as it allows space for gear and batteries. It also is tall enough to stash the IQ with stem mouthpiece attached. This is a packrat case I saw on line for an Iolite. Maybe that will work?I ordered a soft carrying case and received a one that does't even compare to those shown in all the sponsored videos.
