Exactly. I described a useful tool. It has to be used with intelligence...

So what you've really found is an piece of iron in the wall and are inferring that there is a stud attached to it...........

>> Take a very strong small (e.g. 1/2" cylinder, 1/2"

>> thread about 3' long. Tape the face of the magnet
>> near the middle of a 2" square piece of stiff paper
>> (typical copy paper stock, not too thick).

>> light
>> switch or outlet box, as these are often mounted
>> nailed to a stud.)
>>
>> To use the stud finder, place the paper side against
>> the wall, hold by the string about 18" from the
>> magnet. The paper keeps the magnet from marking the
>> wall, and also keeps the magnet from rotating on the
>> end of the string. Now oscillate the contraption
>> like
>> a pendulum, with the paper side against the wall.
>>
>> If your "pendulum" is 18" long, the period (back and
>> forth) will be 1 second. If you swing it so it
>> traverses about 20", the magnet won't actually latch
>> onto the nailhead, but it will hesitate very
>> distinctly as it passes the nailhead.
>>
>> Move the magnet up about half the width of the
>> magnet
>> with each half-swing. When you pass over a nail the
>> magnet will hesitate. Now zero in on that nailhead
>> more carefully. There'll be no question when you
>> find
>> a nailhead.
>>
>> The assumption, of course, is that the nail is in a
>> stud. This is not always true, so renew the search
>> in
>> smaller sweeps of the pendulum, above and below the
>> nail you just found. Once you find two or three
>> nailheads, you can be pretty sure you've found a
>> stud.
>>
>> Seems ridiculously simple, but this method is head
>> and
>> shoulders better than any I've ever tried before.
