We’ve all been there: gold-strapped, starving, desperately mining and wishing there were a means to locate the treasure behind the rocks. Or maybe you’ve fought past that point, and you’re building vast networks of tunnels and on the lookout for an easier approach to help line them up. Or maybe you’re an engineer that would like to find a better look at buried circuits. Whatever the case might be, everyone can agree that X-ray vision couldn’t hurt. That’s what this is true really for!
