Newell Gurus

I bought this on ebay for $55 and its as old as I am but after cleaning up the potentiometer  and the battery connection it works fantastic, its found more leaks  than I ever could with bubbles. Found a leak in the bottom on my drivers side tag axle air bag and many more!
It looks like a Ray Gun from my cartoons days.

That is freaking cool!

Do you have to have a permit to carry that?

Can you image pulling that thing out and pointing it at a stranger and watch their eyes, then tell them its a Geiger Mueller tube and your checking for contamination. Ha!
