LRL working principle solved !

[Funfinder]

Good news for you all, the speculation why and how (our actual "working") LRLs are reacting on distant metal targets seems to be solved.


I found the solution-key yesterday while watching a report about RFID chips or exactly RFID active and passive components:

As you may know RFID-tags or chips don't need internal power source.

Like hidden metal objects they are working as antenna, reflector or EM-field consumers (through eddy-currents or energy-absorption).

The "living" RFID circuit contains a high sensitive field-strengh sensor so it recognises if the RFID chips antenna (resonance-circle)
is consuming energy from the radiated EM-field.
This is comparable with no battery diode-receiver (crystal-radios) that are using a high-gain antenna. If the antenna is good enough
those can suck so much AM-frequency energy from the field even
an audible noise by speaker is possible, not just ear-phone.

RFID-chips with high-gain antenna (size up to 5x5cm) work even
at a range up to 5m distance.



Now what situation do we have exactly with LRL?!


A person stands on a flat site, sourrounded by a wide spectrum EM-field. His LRL detector turns slowly around in this environment until a certain position is reached where the signal-trigger circuit comes in action.

What causes this trigger to switch or beep etc.?

Of course a distortion of the EM-field. If the LRL contains two coils those are acting like 2 directional magnetic antennas and if those became imbalanced (because of the field-distortion) at a certain spectrum the LRL recognises this.

The underground metal object disturbs the usual EM-field because it either reflects or consumes the EM-field and so leads to a distortion.


Important:
We have 2 different levels of "surface" - ground and air that also interacts. But the through metal objects distorted ground-EM field has the possibility to affect and distort the EM-field above the ground, too, and especially very significant if the detector is located just 1-1.5m above ground. And the usual EM-Field if distorted may also lead to distort the vertical static power field!



btw. here we have the opportunity for interesting test - how strong the LRL reacts if its located and used just 0.5m above the floor compared to 1.5m above.



Moisture and mineralic stones weakens the field and "reception" or reflection quality depending on their strength. Even the surface of the ground already reflects a huge range of the EM-spectrum, but it really depends and those waves also have a magnetical dimension.


The steel-frame of a building works different as antenna or reflector for EM-waves than a buried steel object.


Since we know already that the buried or hidden metal objects either reflects, consumes or distorts the sourrounding EM-field energy the only question remains:

What EM-spectrum works most sensitive and powerful for detection.

This also regards the magnetical pulse fields at certain frequencies.


We know an usual buried metal object on its own will not radiate / transmit any certain energy (as long as its not radioactive or highly heated).

Otherwise it would be simple to detect 'cause a huge 5kg gold-"nugget" would transmit over miles his "here I am"-signal and a sensitive directional receiver could locate it easily.

But the question is:
does a certain alloy or kind of metal starts to create harmonics or resonances waves if there is a powerful enough radio-source connected, even if that metal-object buried underground.

Because this will be the final question:

At what EM-field band the passive induction imbalance LRL detector does react and is this a direct result through distortion, reflection or consumation from the buried metal object (comparable with the usual magnetometer field detection methods)

OR

does a certain EM-field frequency or a larger range of that lead to special harmonics, vibrations, resonance, frequency-up-or down-convertion, shift in polarization etc. affecting certain kind of metal (especially after long time remaining under ground) which the LRL picks up.

If that observation about the LRL that it has lost 50% of sensitivity after analog TV station transmission stop ist true, it could lead to the conclusion that either the LRL receives the imbalance of the VHF frequency spectrum or - and this is much more likely - the TV VHF signals have been used by the buried metal objects for converting that energy into a different level or frequency.


Finding this out is very simple by taking a closer look what the LRL exactly detects or what sourrounding EM-field radiation exists in a certain country.

It also would be possible to irradiate a certain kind of metal object with all kind of different frequencies and at the same time testing with a broandband receiver if this metal "creates" any special harmonics that are strong enough for long range detection.



Perhaps Brazil has a totally different shape of frequency-spectrum that is needed to "inject" enough energy into the buried object until enough detectable converted energy or distortion has been created and thats why the Mineoro just works there.




If we take a closer look at those Zahori circuits those are simple static-imbalance-detectors with directional antennas but I doubt just only by distorted static fields we could find buried metal, especially from a distance.

There also has to be the magnetical component of the EM-field distorted (static is highvoltage direct current DC, EM-field is alternating current AC) so the LRL with its directional magnetical-loop antennas can pinpoint into the correct location.


But I hope now its finally clear what gots detected is the imbalance of EM-field regarding its intensity or its distortion at a certain frequency or area level!


PS
And perhaps the explanation why dowsing rods sometimes work also is imbalance of the usual static field.
If there is a very strong thunderstorm in the mountains it even can lift up your hairs because of the very strong static field.
Perhaps in an equal kind the dowsing rod user feels somehow the static field difference and the very sensitive balanced
rod gots lifted or teared down by the changed static field, if the underground fieldcharge gots distorted by metal or water etc.
