Any good stud finders?
Despite being well warned against wasting my money on a stud finder, I did buy a Zircon i500 multiscanner today. I am happy to report that I have been getting some good info from the device.
Watching the DVD which came packaged with the unit prior to using it, I found that for my walls, plaster over wood lathe, the best mode is the metal mode, then look for nails.
That helps a great deal. I am able to discriminate between nails and larger metal objects such as BX cabling or plumbing in that nails usually produce a much weaker signal, and are passed by very quickly.
The normal stud finding modes (regular and deep scan) don't seem to do very much good on most of my walls, as was stated by others here.
But I am finding the i500 quite useful in locating the wiring. I can detect most BX using metal mode, and all of the Romex using either metal of AC mode.
I have learned in the few hours I have been experimenting with this tool that one must be very patient with it, and learn how to interpret it's responses.
So far, I would say that the i500 is certainly more use to me than nothing at all.
I paid $40 for it at Home Depot.
