Dear colleague professor jack.
My English is too poor to understand all your question.
The best way to get answers is to build one (parts needed are very cheap) and test it.

WM6 is correct.
This detector is a VLF receiver which has been modified to use a ferrite loop.
The original design before the Arial version or the ferrite probably used an air coil loop.
VLF receivers are known to be good to map buried objects which are large, such as large rock formations, or sometimes very large objects such as a buried car.
The ferrite modification is expected to modify this detector to allow finding smaller objects. It may also reduce the maximum range of detection.
All of the VLF locator projects we see in this forum are only experimental designs which people build to see if they can improve the performance of a vLF receiver so it can be used to locate smaller metal objects from a distance.
None of these have been shown to have any consistent abilities to find buried jewelry or treasures. They are simply experimental projects to try to see what we can find.
There is no data base for what depth we can expect for the design shown above, because the performance depends on the details of how the circuit is constructed and how it is used.
And the performance also depends on what kind of soil it is used in and what is the moisture content, and what VLF/ULF noise happens to be in the area where you are hunting.
The only way to know how this circuit works is to build it and test it to see for yourself.
If you are not satisfied with the test performance, then you can modify the circuit to see if you can improve it.
This is what every other experimental VLF project builder here does.
Best wishes,
