I think the days of "dug up plenty" might be coming to an end. Well, maybe not an end but a slow down is expected. First of all, a decade of digging does make a difference, the quantity of finds is reportedly reducing. Secondly, a new law has been passed in Russia, I'm not very familiar with it, but the general sentiment is that it is meant to crack down on metal detecting. Of course Russian laws are fickle and are not enforced equally, only time will tell if this one will really have an impact.
