I just want to quote this...
" The pair are choosing to remain anonymous, Kagin said, in part to avoid a renewed gold rush to their property by modern-day prospectors armed with metal detectors "
My guess is that everyone else that sees this and is a non detector will presume if we ask anyone for permission to detect their property they will think they have a large sum on money....
Also more people getting detectors that only care about the money and not have pride like we all do with out hobby.
Great find for the people but i can see this not being so good for us.
