They don't make light like they used to, and lines, particularly vernier lines, have gotten much farther away. The universe is expanding, and we're becoming less substantial all the time. For scaling, I use this snap gage. Someone used to sell these, but by the time I decided I wanted one, I couldn't find them any more, so I stole the idea and made this. I find it accurate enough, and it'll reach anywhere I need it to, giving a quick reading I can see. For what it's worth.
