It is theoretically possible that when searching in non-conductive soil that has an area where there is an anomaly of very conductive soil, a VLF detector may be able to detect the conductivity change in this area of soil. This means the conductivity of the "conductive area of the soil" must be similar to the conductivity of a metal object. But I have not seen any testing results that demonstrated there are areas of "more-conductive soil" that were detectable with a VLF detector. The only exception is soil that has "hot rocks" or pockets of conductive sands in it, or in very iron-rich soil similar to the soil found in the Australian gold fields. These areas that have pockets of "more conductive soil" do not produce treasures, but only areas of conductive rocks and sands.

You know why the pistoldetector catch this ELECTRIC EMISSIONS FROM BURIED METALS ? Becouse as the PASSIVE RECEIVER,circuit very sensitive to electric and electromagnetic fields.
And my theory is that the GOLD as much stronger electric emissions than other metals. The Gold acumulate much more energy ,but other metals acumulate and irradiate less energy.
