Hi mehdi,
The Zahori is basically an electric field detector. It detects variations in the electric field in the air.
If it beeped at a place where you found a coin buried, it may have been beeping because the coin caused an electric field to appear, or maybe because something else at the same location was causing the zahori to beep.
Do you remember if the ground was wet or not?
Were there plants or grass growing on the ground?
Were there other things on the ground like fence posts, buildings, telephone poles?
Was coin buried under a tesla coil?
was the ground flat? Or did it have a slope or hills on it?
Were there any big rocks nearby?
If the humidity was high, then the air was more conductive that day, and it would take a stronger electric field to make beeps on a zahori detector.
But you would also have less interference from noise in the air on a day with high humidity, so easier to find weak signals.
One thing that does not make any sense to me is the brass sample in the coil. This brass does nothing that I know of electronically.
Maybe you can make a second coil identical to your first coil, except do not put the brass sample. Then see if the zahori works the same with the brass as it works with no brass.
If you think about it the whole coil is made from copper. This is the same as having a copper sample.
So you could make a coil from aluminum wire to see if this is the same as aluminum sample, and iron wire to see if this is good for iron sample.
All of this seems silly to me. But we can find out for sure if you make a second coil with no brass sample to see if there is a difference.
Thank you for the report
Best wishes,
