Hello,

I have the need to drill a number of holes in a residential ceiling with
ceiling heat (house built in early 70's in Oregon).

As I obviously do not want to drill into any of the elements, I need to know
a method for locating the elements.



What about one of the little proximity testers for electricity? Turn
the thing on and see if you get a pitch change near the wire.
