wm6, you are also into amateur radio, right.
does the wire of a coax cable transmits the electromagnetic field aka radio waves -
even 20 or 50m if amplified - through a "tunnel"?
So every conducting material transmits electricity with its em-field (the moving electron spin creates magnetic field lines around) - electrolytic ground, too. And instead of an antenna made out of metal you also could use an antenna made out of powerful electrolyte!
waves = amplitude changing electro-magnetic fields caused by directional changing electricity flow.
The issue we are facing is:
waves can penetrate almost to non cunductive space better because there is no resistance (thin air, vacuum, plastic, wood etc.) btw. the term waves is principally wrong and only fits to audio "moleculare resonance" vibrations. there is no "matrix" in vaccuum where the EM waves could ride so they have to be "radiating energy particles" on its on.
but with metal detection we try to induce em-fields into ground and metal so some interaction can be measured. Therefore of course it makes a difference if the ground is electrolytic or not - as Morgans tests did show.
The question is:
if LRLs recognise ground capacity values created by metal in combination with electrolyte what kind is it exactly?
Is shuch a "ground-complex" some kind of shielding of the earth magnetism field that becames detectable from far distance or what else? Does it distort the high voltage eletrostatic vertical field?
And if high humidity in air (and probable in ground, too) blocks this LRL effect why it is so?
The easiest way to find this out would be to know exactly what the LRL electronic does detect and what it doesnt and if there is a problem with it exclusion tests should be found so we can discover if the lrl is capable to detect this or that.
