Has anyone heard of/used one of these? As I understand it, it's a blind tube - you don't see through it? You look into the tube and see a dot or something with one eye, and look at the target with the other eye, and somehow the two images will line up? If that's true, then the images of sight and target are not actually physically superimposed - they are only "superimposed" in your brain. Is any of this correct?
