the word stud applied to what is a piece of wood is akward, as is the
use of a stud detection tool, which normaly have a metal detector. I
have examined a few and they will not say on the packaging wether they
detect a wooden baton or the nails that hold plasterboard and laffin
plaster wood to the wood.

The good ones will detect the wood - there does not need to be any nails
to present to detect the stud position.

If the wood that is used to nail
plasterboard to is called stud,

it is... (not to be confused with threaded rod that is sometimes called
studding)

then it would require more than a
metal detector to find it.

True, you need a stud detector.

If these detectors only find the nails and
it is the nails which are detected, then the detectors should be
called metel detectors.

True, but that is not hoe they work - some stud detectors will also find
metal - but that is an extra capability.
