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

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

I have never (until now) heard of the outer conductor in a concentric
cable being called armour. To my mind it is just a concentric
conductor.
