The reviews on Amazon say, rather obviously, it's no good - it's detecting metal so it won't detect metal underneath. There might be instruments that will find 'more' metal but I guess that they'd be rather expensive.
I tried that, but in that case it was tiled plasterboard. The thickness of the tiles meant neodymium magnets didn't 'pull'. The Zircon worked straightaway (it uses capacitive sensing I assume).

slide them apart
I once worked in an office and when relaxing one day spottd an 18" string of small holes in a straight line running across the ceiling before it turned 90 degrees and ran another few inches before the genius hit the stud. No attempt was made to hide his stupidity
I've never used the technique before but yesterday wanted to find a stud for a pipe clip.
I used a 10mm dia x 2mm thick magnet.
Although it was very difficult to find the screws, more like a needle in a haystack, it worked well. Where I was able to leave the magnet in place on the wall as a guide.
