Hi Ivconic
I was being sarcastic about the 20m, but i am still interested in the possiblitity that log time burried metal could induce an anomaly in the natural electric field above earth (to resume)...
Instead of detecting the metal itself, (that as we know can only be detected at short distance),detecting this effect could be done farther away.
