Deciding to dig | CBC

I am "small i" involved, as a GPR supplier to many of these searches (not the above linked stort). I do training for GPR operators, and have sold GPRs to a few First Nations. The above is an important part of geophysics, which in industry we refer to as "ground truthing". Taking the decision to dig is difficult, particularly when there are cultural sensitivities about disturbing remains. AMA.
