Hi Esteban,
I see... so it's fiberglass or gum (I think you maybe mean "rubber") that it's there as non-conductive medium, cause maybe there are electrostatic considerations like small charge flow must be prevented in such devices and some materials are not so good for that.
For example, fiberglass used in pcb (epoxy and fiberglass actually) is good about such stuff cause both glass and epoxy are excelent materials.
Sure, fiberglass can be electrized but unless you rub that stuff with e.g. some tissue/silk it wouldn't happen easy.
The wood, instead, have very small leakage currents that could possibly give wrong signals to such sensitive "electrometer", cause zahori, indeed IS an electrometer.
So, it's like in gold leafs electrometer the glass acts as insulant there and leafs are just connected to the rod and far away other conductive mediums.
Now, the problem is: if the zahori is just an electrometer (and indeed it is) how can it show the presence of a target ???
We must face the "fact" we need an electric field around a target to explain why the zahori could work as lrl for real.
So, is there any electric field ??????
Very confusing... I don't understand why the target must show, inside soil, a different potential than soil around !
What do you think about ?
Kind regards,
Max
