[Esteban]

photo seems very seplice be built over the years you have successfully reduce everything to the minimum or e 'a new project

Hi, new project.

Two ferrites glued between them.

"Bridges" I cut of old equipment... gold coated. I have many useful "trash".

Hi Esteban, your ferite sensor which frequency accepts ?
(may be received 59,5khz - 60Khz )

Ferrite captures the electric emissions of the long time buried metal but when inside a metal box, this acts as a shield for the elec. field.

There's a way to overcome this and I'm sure Esteban will eventually know about it or probably he already does.

Electric emissions from long time buried metal are a result of ions formed in damp soil when combining with other compounds in the soil that can dissolve trace amounts of the metal. If gold is contained inside of an iron box, or a plastic box, or any other box that prevents the gold from coming into contact with the damp soil and the chemicals that can dissolve trace amounts of gold, then there will be no electric emissions, as there are no gold ions in the soil.

I would think the best way to overcome this is to bury the gold without any iron box to prevent it from contacting the soil and creating trace amounts of gold ions.*

*(This solution will work ONLY if the trace amounts of gold ions that dissolve into the damp soil become concentrated enough to create an anomaly in the soil that can be detected with an instrument that is capable of detecting secondary effects associated with the presence of these ions).

Best wishes,

Hello Forum ,
For mi the " halo effect" exist , for sure because many time i find coins in the soil remove it and pass over the coil (VLF) you have sometimes the Halo effect a small signal result and in 10 o 30 second this shallow vanish...
But I do not know if it is electro chemical o electro magnetic o other effect ???

A VLF detector is only capable of detecting things that will change the magnetic effects of the search coil. It does not detect any chemicals unless they can generate eddy currents that allow changes to the magnetic effects. The chemicals that are known to allow eddy currents to form are the metals that conduct electricity, such as copper, nickel, iron, aluminum, gold, silver, etc., and mixtures of these metals.

It is theoretically possible that when searching in non-conductive soil that has an area where there is an anomaly of very conductive soil, a VLF detector may be able to detect the conductivity change in this area of soil. This means the conductivity of the "conductive area of the soil" must be similar to the conductivity of a metal object. But I have not seen any testing results that demonstrated there are areas of "more-conductive soil" that were detectable with a VLF detector. The only exception is soil that has "hot rocks" or pockets of conductive sands in it, or in very iron-rich soil similar to the soil found in the Australian gold fields. These areas that have pockets of "more conductive soil" do not produce treasures, but only areas of conductive rocks and sands.

Hello J_P

It seames you know a lot of secrets about metal in the ground...
My theory is :

1-THE GOLD AND SILVER ACUMULATE MUCH MORE ENERGY THAN OTHER METALS,when buried underground for many years.

2- THERE ARE MUCH MORE ELECTRIC EMISSIONS FROM THE BURIED NOBLE METALS THAN OTHER METALS.

3-The Pistoldetector is sensitive to changes of variations in ground electric field,so it can detect the ELECTRIC EMISSIONS coming from buried metals,becouse the PASSIVE RECEIVER WAS MADE TO CATCH THIS PHENOMENON.And this phenomenon you mention above,and for sure its cientificly proved...Your next step is start believe in some LRL devices

You know why the pistoldetector catch this ELECTRIC EMISSIONS FROM BURIED METALS ? Becouse as the PASSIVE RECEIVER,circuit very sensitive to electric and electromagnetic fields.
And my theory is that the GOLD as much stronger electric emissions than other metals. The Gold acumulate much more energy ,but other metals acumulate and irradiate less energy.

I have my doubts... As gold corrode (no corrode, except "low gold") less than other metals as bronze or copper, is more difficult to be detectable at distance, except if you can build device with high selectivity. Except treasure size or cache, small gold items are reluctance... Bronze and copper and even silver coins not pure (mixed with copper) are more "ease". With absorptive method found a silver 1797 Spanish coin (some "black" for the time), but just five times can be detected and fix the site. No more than 4 meters and depth 20 cm.

How do you pinpoint?

Finish and works great! Treasure can't scape of it! Is easy to mount in a plate (in this case, fiber glass), all are at hand. Radio is not use here, just amplificative stages.

How can you tell gold from silver with this?
Can you pick up rings and how far?

No at high distance, just 5 meters. Better for big items as treasure.

Now I replace magnetic speaker by piezo, this not disturb as speaker based on coil and magnet. Also consumption is lowest.

Now, I'll replace the audio amp of radio by circuit based on NE5534 or similar. This is just for to try ferrite.
