pen-like run-along-the-ac-line "locate-the-break" tester?

Question

I once saw an electrician find a break in an ac-cable (110 volts) by running some pen-like instrument along the outside of the cable, down its length. It maybe beeped at the break, or a light turned off when the voltage dissappeared, I forget.

Anyway, I'd now like to get one of these nifty things.

(1) What are they called?

(2) What brands?

(3) Prices? Price vs quality?

(I'm no professional; I'd just use the thing around home, only once in a while, but it's sure save a lot of time, sweat, and tears -- and blood too, maybe!)

So, suggestions?

Thanks!
