Everyone doing air test on a Machine is fine. gives you a ideal of what to except from it somewhat. But i think when doing one people would be more interested in the Numbers that show up on the screen. Different size Gold rings so on. What do you think? They show the item app size then tell you I'm at 5" 8" so on but showing on camera what the read out is. I think that would help more than anything. If their testing stuff on a detector you have. Just my thought
