With a cable/metal detector

Will that pick up plastic pipe?
Though hopefully it wouldn't be carrying gas.

Hopefully anyone using plastic will have threaded it through the
joists rather than notching. I reckon I'd stand a reasonable chance
of picking up notches in joists with my stud detector - as long as
they were not filled with wood pipes - not tried it though, any
thoughts?
