Inventors hello to all.
My humble figure.
Sed.Probes the ground in a triangle to have a concentric radiation underground.
Geo. I think that each antenna will sow the ground surface wave. Im only interested in measuring the electromagnetic wave Reflected from the underground treasure with a very sensitive receiver. Narrowband = 100Hz max. Low noise. Sensitive = 1mikroVolt. There may be a vertical antenna ferite.
Micebg. I know the history of art, now I go to do already without fear.Do private mini-VLF radio station located in a fixed location and look at neighborhood.
I look forward to constructive criticism.
Best regards
