Before some days a friend told me that he found a big silver coin with PDK 2.1. He had very strong signal. Also other persons at Greece found coins with PDK. This mean that the phenomenon exists.
Now i think that it is good time for understanding the phenomenon because FrancoItaly has an existing phenomenon at his test area (from a buried silver coin), and i believe he has a magnetic field meter so to see if the phenomenon is a magnetic field????
What you say Franco?????
