1/4" of wood, maybe 1/2" if I already know where to look, and that's with the sensitivity screw dialed up as high as it will go without perpetually signalling.
I didn't replace his battery, but he told me he thought it was still good. Would a weak battery make any difference to how well this thing could detect metal? I'm not going to risk my blades after assessing wood with this thing, so I'm wondering if the Wizard III (the larger one pictured on the above website) could do the job well. I've got a pile of reclaimed pine with thicknesses as large as 2" strong to assess.
What have your experiences with metal detectors been?
Thanks.
