I know they are not accurate but I am trying to locate the uprights in a
stud wall. Now I have set the detector based on a known wall (I built
it) and it accurately shows the location of the studs, now when I apply
this setting to an old wall it either sounds continiously or not at all
(if I adjust the settings)
This particular stud wall when tapped appears to be more hollow than
anything with just one part sounding solid, near the center (and not
where I want to locate a fixing) the wall is approx 6 ft wide and the
usual height and definitely plasterboard. Its also on the end of house.
Is there some peculiar way of fixing p[lasterboard that I am not aware
of that would allow for lack of studs? To the best of my knowledge the
wall is original and house built 70s ish.
