Tvad, using a penny or dime is how old timers determined if it was time to buy a new set of tires. If you could see the top of the President's head you have enough tread left. If not, time to fork out the dough!

The Electron-O-Meter would be a precision device utilizing milspec knarkle valves, and it would come in it's own faux alligator, snap-close, Naugahyde carrying pouch.
We could emboss the image of a penny on the pouch.
