Halo Effect - WTF !!!!

[Esteban]

Heh..!
No electric fields arround burried metal for long time, Esteban. No such things. How can you measure something that dont exist?
I accept existance of so called "phenomena". I also can not explain what is all about. But also i am not that ignorant to accept some false theory about it.
"Strange sound" can be produced when highly flammable organic gas "meet" ordinary fresh air. Many times seen. In my country also people do beleive in theory whis claims; " ...when you see some weak,mum fire somewhere on some place, that is sure sign of burried treasure,under that spot...".
People evolved legend and sort of prejudice upon this natural phenomena, very oftenly seen. It is funny and sad at the same time to see groups of diggers how diging huge holes...tunnels on simillar places desperatelly searching for burried treasure.
We all are fully awared of mentioned phenomena.It exist for real.Nobody can deny that.
But also nobody gave sane explanation of it so far.Fact.

Ivconic: I detect it many times with open base NPN or PNP transistor system. I know about the gas or light emanated from this buried for long time metals. Also detection deppend if you're positioned in plain terrain or high terrain.

So, my conclusion is this: small electric field in order millivolts exist in vecinity of for long time buried good conductive metals (small size).

Bronze and copper are more strong. Silver and gold less in concordande in grade of corrosion. Round objects "has" more "signal", etc.

The experts don't measure electric fields around conductive metals buried for long time, don't know why.

Ok, mmmm strange
I was talking about magnetic field,but taking both into account and beeping only when both are present may be a solution....regards,
Fred.

Ok Esteban ,it doesn´t look so easy at first glance.And i don´t see any explanation for "many meters" detection in this theory.
From my post i was expecting some reaction from the experts...strange

Maybe that is right about an electrical field around an object, along with chemical change in surrounding soil, It seems possible. I think there is much more to all this than a simple no, this is no halo effect.

[Fred]

Now, all you're more able for to use such phenomenom for to detect from some meters. Since many years I insist in it here.

Halo Effect

Would this maybe describe the Halo Effect?????

ION MIGRATION

Many of the chemical compounds that we commonly call "salt" are hygroscopic, thus they attract water. (Check on Google for hygroscopic salts)

Now, you used an interesting word: "migrates" Migration is how I explain the halo around gold.
gold is very resistant to oxidation, but it has another important characteristic that could explain the halo around long time buried gold.

Ion migration.

I am not very good at explaining things, so I will have to think of a simple experiment that anybody can try, to prove my point.
Here is a hint: google "potato battery" or any other vegetable or fruit battery. These simple experiments are beautiful samples of natures way of creating electricity and galvanic currents and therefore ION MIGRATION.

Tinkerer

Tinkerer, are you trying to tell us that your new PI discriminator is capable of detecting IONS?
Do you know how small IONS are?
I have seen your mention of detecting a target of 0.005 grams of gold. That already sounds rather exaggerated.

In general people talk of grams or in the extreme penny weights, but to talk of a target of 5 miligrams of gold sounds like smoke and mirrors to me.

But even then. Do you understand how many times smaller are IONS compared to miligrams of gold?

I think you have a "SMOKE DETECTOR", BS walks!!!!!!!

Maybe :
A buried conductive material could influence the surrounding materials without chemical exchanges, in a similar way that a burried magnet would magnetise surrounding (magnetisable) materials, that in turns would do the same , extending the original effect.
Resulting realigned magnetic field would be destroyed by digging (like when breaking a magnet).
A ring would be perfect for creating such field, just like in a generator...it is just a loop of wire.
That make me also think of a proton magnetometer constantly energised by natural fields , the metallic object being the coil

Fred.

The "atmosphere" around this buried for long time metals has an electrical field. Once we found small treasure (family jewels) contained in small silver recipient. Over the recipient a square stone "press" the recipient. When we retire the stone, was liberate a gas with characteristic sound.

Halo explained

Tinkerer, I take it from your post that moisture migrates to metals underground? If that were the case even though it would have nothing to do with oxidation, that would make for a better signal, can you elaborate on that?

Many of the chemical compounds that we commonly call "salt" are hygroscopic, thus they attract water. (Check on Google for hygroscopic salts)

Now, you used an interesting word: "migrates" Migration is how I explain the halo around gold.

Could this be a plot showing the halo effect? We are still studying this plot and site. Scroll down to the bottom of the page to see the plot. This is not a joke it was done using the Garrett XL500 and the Arc-Geo Logger. The two strongest points on the ring was hit by the guy using different dowsing equipment. I know those here don't use dowsing , so just look at the plot.

There is a metal target there, but the ring around it and where the rods directed is in line with my ring theory. Could this be a ring halo?

Halo Effect

When I said "I believe", I meant "it is my understanding", I did not imply that it needs an "act of faith" to believe in the existence of the Halo Effect.
The Halo Effect exists and there are several ways it can be produced.

If we fully understand how it is produced, we may possibly be able to design better metal detectors.

A piece of metal that is buried for a long time is exposed to water or humidity.
Oxidation takes place. Products of the oxidation migrate into the surrounding soil. For example the "green stuff"mentioned above. The dry oxides in themselves might not be good conductors, but the watery solutions thereof have different characteristics than the dry oxides. many of these oxidation processes produce metallic salts that make otherwise inert water to become highly conductive. Table salt is a combination of the metal Sodium and Chlor. Ad salt to water and the water turns into a conductor. This is very obvious when you go metal detecting in the ocean or the salt water beaches.

Salt is also hygroscopic, that means that it attracts water. Where there is salt, there is always a certain amount of humidity. That means that there is a "pocket " of conductive soil surrounding the long time buried target, that enhances the response to the detector.

Now what about gold? It does not oxidize. Well think about it!!! It is all the same but a little bit different.
I will tell about the Halo Effect on gold the next time.

In the mean time maybe somebody could explain to me why a gold nugget or ring gives a non magnetic response on my PI discriminator but a 0.005 gram gold leaf gives a negative response just like a FE target.

What is so different with gold?

Tinkerer

[ivconic]

Here's what I think which is unscientific and just my opinion. Maybe all of us would agree that iron can have halo effect? Next, copper and all its alloys break down when exposed to the earth, you know that green stuff that forms on it? So my take is that copper and its alloys will cause a degree of halo in the ground, that is the material off copper will scatter in the ground around the object causing a friendlier atmosphere for the detector to see it if the corrosion factor doesn't subtract from the gain. Lastly the best debate either for or against halo is silver and gold, seeing that they don't breakdown or corrode like most other metals but in my opinion there may actually be some halo around them also. Ever take a piece of metal and use 600 grit sand paper on it? It will polish the metal, actually you are taking off a very small amount of metal even though it would take some very expensive measuring devices to measure the amount taken off so here is the question, do minerals in the ground chemically break down gold and silver and any manner at all, if the answer is yes then there is the possibility of some halo effect to occur.
The surrounding ground if it has the halo effect in theory is undetectable in itself but detectors see minerals, even if the operator is unaware of it, right, ? Then it stands to reason that the ground around an object in the ground that has been chemically altered by the presence of the metal material could cause more favorable conditions for a better signal.

I realize there will always be some who think halo is for real or some who don't. I believe in the halo effect from what I have experienced while detecting or maybe the detector gods were with me at those times.

Most logical explanation. I agree.
Green stuff we called "patina".
More green stuff on ancient coins - better prices...
Bronze alloys do form high quality green stuff. But if Cu is in higher percentage in that alloy, green stuff is less quality...
etc..etc...
