This one works great.
Harborfreight.com (their mailorder outlet) has them for $29.99. I bought one at HF's sidewalk sale, but I don't think they are usually in their stores.
Here's their product description.
These are the same thing TSA or other security personnel frisk you with at the airport, etc.
I used it to get all the nails out of the redwood lumber I salvaged when I took down a small barn. It not only found every nail, it even buzzed on the rust residue left in vacant holes where old nails had been. It was also helpful when I pulled a nail and it flew off somewhere and disappeared into the gravel driveway. The detector found it much faster than I could myself.
Then later I had another barn re-roofed. When they finished, I went over every inch of the dripline and found all the roofer's nails I would have driven over to get into the equipment stalls. About a double handfull of nails, and every one had been in the path where a vehicle would find it eventually.
A tip if you are too impatient to read the manual: peel back the rubber handgrip to find the sensitivity adjustment.
I've earned back my $30 already in damage averted to saw blades and tires.
Add: I reach for the detector every time a small part rolls under the workbench out of sight. It finds the part immediately.
