Seem to work fine on ordinary cable but not on my armoured incomer. I

me drilling into another armoured cable. ;-)

Out of interest, would the type of armour make a difference (say steel
versus copper)?

They aren't meant to be cable detectors. Surely a proper detector
would
be better?


Never heard of copper armour.

Most houses built since the late 60s have an incoming supply that uses
copper armour.


Wrong.
They use steel armour. Copper is not an 'armour'


Yes. Point noted and I was wrong with what I said.

It was more to say to newshound (and other posters) that there are cables
with copper not steel "outers" that look like SWA. The clue being in the use
of the letters SWA.
