Was it a little box that he clipped on to one wire, and a probe
thing with a speaker that he used to find the line?
If so, this is the same or similar to what telephone installers
(and sysadmins who ran networks before modular cat 5 cable) use
to trace wires. The warbler box just puts a signal on the line, and
the probe thing's essentially an antenna that picks it up.
I'm sure that someone who understnds the theory will explain it all...
I've used them to trace phone wires and network cables. I don't know
if they work on coax but I don't see why not since they work on twisted pair.
I bought a set for about $60 from Frys a few years ago.

How about welding the nuts onto stainless hose clamps. That way
there's less damage to the pipe itself and you can remove the whole
thing without leaving somethign behind. And if you muff the welds
you won't have damaged an expensive pipe.
