I've got some old barn wood and some "urban timber" to cut up, and want a good metal detector. I bought a Lumber Wizard (full size model) and it wouldn't even detect a drywall screw through 3/4" mesquite. It was real flakey, sometimes beeping and sometimes not. I tried 2 different brands of new batteries, and no difference. We tried the other one in stock at the store, and it performed the same. This was with the fine tuning as the instructions say.
Is there a good metal detector that will work on 4" thick barn wood? Basically I would like to be able to get a good reading at least 2" deep.
Thanks,
Greg
