Best accurate sensitive stud detector What's the differences?
I'm an electronics tech and yet don't understand, exactly, how all stud detectors work. (1)
The last time I looked at them closely was about 1980. I want something that will be very accurate as to the center
of any stud.
With the major improvements in all technology I figure it's time to get a quick lesson and recommendations
I have two houses and both have thick walls of plaster and metal lathe over wood frame. Some walls are 6" thick or more.
In some cases I might like to know about detectors that are able to penetrate even more than the walls above.
I want to install into the rafters some screws which should be put exactly in the center of the stud (rafter).
Other cases I want to be sure that I've hit the center of studs where shelves might go. I'm just beginning my work on the
2 homes so whatever I get will be used a lot.
(1) At one time the way to detect a 'stud' was to look for the nails in it. So a detector would employ a magnetized needle.
A compass would be similar. But a good knock could find the stud as easily by listening to the sound. And then tapping
in with a long small nail would be the final test to see if you actually hit it.
