Seem to work fine on ordinary cable but not on my armoured incomer. I
suppose I shouldn't be surprised by this but clearly they're not gonna stop
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?


I wasn't intending using it as a cable detector. My folly was to drill
(deliberately) into an old copper pipe to determine whether it was gas or
water (having turned off both first) prior to removing the "pipe". I forgot
the third option. ;-)
