Of course, you don't really have to worry that much about brass screws.....
Also, I don't think studfinders (if that's what you were talking about) work
on magnets, they detect changes in density to show where the studs are.

A new Forrest WWII or Freud blade works well for that too...

destroyed all the carbide on two embedded nails. ;~(

This tool looks great, but I'm going to have to think about whether the 100
dollar price is justifiable given the amount of work I do, the amount of
work I'll do in the coming years, the cost of possible blade replacement,
&c.

The metal detector will work OK but it will be a bit clumsy if you plan on
using it a lot. A smaller metal detector, like the ones that they use on you
at the airport when you fail the walk through scan, are available. The ones
that sell for around $100 work fine, but the smaller and cheaper ones aren't
very good. Woodworkers Supply and Rockler carry them or you might find them
at a local security and police supply store.

How about one of the magnetic dry wall nail finders that were used? Or a
compass direction finder. Of course this would not show a brass screw.
I've found that a jointer with newly sharpened blades will find every
piece of metal in a rough board.

I recommend the Wizard III. It easily finds the screws in my left leg
or a tidbit in pallet wood. I bought mine at Woodcraft but there are
other retailers.

What scanner size do you have? I have the Wizard III, the larger
Wizard. This unit picks up the smallest of metal pieces. I havn't
used the "Little Wizard" (about $20), but have read comments that this
smaller metal scanner is not nearly as sensitive.

I got hit twice last night on some old poplar I recovered from a
job site. Those 15" planer blades still found a screw after I used
the "Wizard" brand scanner. I hate changing planer blades.
On my Delta DC380, I don't think I can even use the "shift the blades"
trick to help the situation.

IMHO, no. The "Wizard" detectors just aren't very good.
I'm using a mixture of a mil-surplus mine detector (which isn't very
good - a cheap treaure-hunting metal detector works better), but mainly
I use blades I don't care about too much. Unless you're encountering
hardened drywall screws, most nails and woodscrews are actually pretty
soft.
