A new invention, Craig explained. "All you need to do is to move it so that little dark spot falls directly on an object. Pull the trigger-- the bullet strikes the dark spot. Even a nervous and unskilled marksman becomes a good shot in the dark. He can even shoot from behind the protection of something--and hit accurately."
