Hello Kat. The M40 will locate copper pipe up to 2" deep behind a sheetrock wall. Thank you.
Hello. It will find the nails holding the lath to the studs up to 4" deep which will indicate where the studs are. Look up the Tip Minute # 8 on the Zircon website which is a video demonstrating how to do this. Thank you.
Hello Jim. As long as the ducting is within the tool's depth range (4" for ferrous metal and 2" for non-ferrous metal it should find the ducts. Thank you.
I'm not sure. I never tried that and at the moment I don't have Styrofoam on hand to test it out.
While I have not tried to locate a gas pipe , it does locate metal duct work behind drywall.
It should detect metal ferrous and non ferrous.
no won't work for that
no, get a metal detector
