This afternoon I had a chance to turn the machine on and I experienced something strange, bordering on the bizarre. I've detected this place frequently--normally the ground
is very quite--no stray signals, chirping or chattering from the ETrac. Today, it was like the Earth had turned to foil. Large 5' x 5' swaths of ground were returning solid
Fe-Co readings of 2-4, 4-4, 1-3, 3-5, 2-7. The machine was nulling like crazy. It was doing it on TTF and Multi-Conduct with the 1-3 Fe and Co lines discriminated out. And it
was literally everywhere...
It tried Noise Cancellation up to 6 with no difference or improvement at all.
The ground has gotten progressively dryer for the last month, no rain at all.
What was going on?
Also, I buried 5 pounds of pre-1982 copper pennies at a depth of 17"-18" for a test. On the surface, 1 copper penny gave me a 12-44, 10 copper pennies gave me an 11-44,
and 5 pounds of copper pennies gave me a 11-36. Buried 18" deep in compressed soil that same 5 pounds came back ALL OVER THE PLACE for Fe: 4, 6, 10, 11, 15, 22...
but the Co remained pretty constant at 34-36 regardless of setting or sweep. Also, while Auto gave a signal, +3 yielded a much better response.
