How to construct a Test area for LRLs

[Geo]

Hi.
Before 2 days i made a test area for LRL. I made it with mercury!!!!
I believe the "phenomenon" to be ready after 2...3 months.
Sorry for bad quality of photos, but i took them with my mobile.
First i opened a hole at 35 cm depth and about 35...40 cm diameter.
I put inside the hole a platter from glass. I filled the platter with soil and i threw the mercury inside the platter.
I closed the hole with the soil and the test area is OK.

Regards:)

Here the rest photos:lol:

Hi Geo,

good work!
did you test this test area with a LRL ?
please tell us about your test...

[sweatofglory]

Hello Geo,

My LRL is set to frequency of Hg but won't be able to detect the buried Hg in my test garden but the gold ring instead. One thing good about mercury is, it will create a signal line to where the gold ring was buried a year ago.:)

Hi Geo,

Hi. As i wrote i will see the results after 2...3 months.
I made the same test before years but the mercury was not inside the a glass platter so after some time (i think 1+1/2 month) i lose the "phenomenon".
Now, i wait.....:)

Hello Geo,

Did you put the mercury inside a platter or directly to earth???

Incredible! If only these things actually worked the way you fantasize. There is no specific frequency(?) for mercury. All LRL/MFDs, if accompanied by a list of frequencies for various elements is pure BS. These so-called frequencies were arrived at empirically, and as such are a totally random selection based strictly on the individual operator choosing them. In essence, these frequencies(?) are totally bogus and a complete waste of time and resources.

Mercury does not produce signal lines. Signal lines are a figment of someone's imagination; probably an LRL scam artist salesman.

I can't think of a single good thing about mercury. If you ingest even a small amount of the fumes/vapors, there will be some liver damage. Handling it is also hazardous, since it can enter the body through the skin.

Burying it in the ground, no matter the container, will only serve to pollute the earth and the water supply in the immediate area.

Back in the late 1970s, we were still etching some printed circuit boards using ammonium persulfate with a few drops per gallon of mercury catalyst, and the mercury catalyst was not actual mercury, but a derivative of mercury. Even that mixture was banned (in the early 80s) from use, and boards were etched with ferric-chloride to eliminate any trace of or use of mercury derivatives.

The use of mercury has never aided anyone in uncovering or locating treasures. Fooling around with it can only cause you harm and damage the environment. :nono:

Hi,

No, I put it inside a sealed glass container to prevent soil contamination

Of course mercury can be extremely hazardous, but it has had uses in recovering gold.
Early miners and panners used it to amalgamate fine particles of gold from excavated soil to make it easier to concentrate the gold.
From there they could easily collect the drops of mercury and heat them until the mercury evaporated and left the gold behind in the heating vessel.

Since July, 2006 the RoHS directive prohibits using mercury and other hazardous materials for electronics manufacture in the member countries of the European Union. The European Union also enforces the WEEE directive (waste electrical and electronic equipment) to keep toxic materials from being disposed of in a way that they can enter the air, or ground water and agricultural areas. Of course, lead, mercury, and cadmium are listed among the 6 toxic materials that are enforced. But these directives apply only to electronic equipment. There are no RoHS or WEEE laws that specifically prohibit pouring pure mercury into a bowl buried in the ground.

Also, the concentration of mercury waste that is considered toxic is 0.1%. If we look at the size of the farmland where Geo's mercury test hole is located, the weight of mercury poured in the ground compared to the total weight of soil in the field will render this plot of farmland to be below the toxic limits for human consumption. So when considering the entire field for an average concentration, this test hole represents an insignificant amount of mercury, and it does not violate the RoHS or WEEE directives designed to protect the environment.

Some quick facts about the RoHS and WEEE directives:
http://en.wikipedia.org/wiki/Restriction_of_Hazardous_Substances_Directive


Of course, any LRLs used at this mercury test hole will be RoHS compliant, as they are covered under the RoHS directive. ;)

Yes, I know. And many miners have suffered health problems and died as a result of using the mercury and then heating up the mercury to vaporize it, leaving the gold behind. Some would put the mercury and gold amalgamate inside a potato, and then roast the potato, sending the mercury into the potato. Not sure what their intelligence level was, but I understand that some would then eat the potato. :(

Whether the mercury used constitutes a toxic waste, or not, is a moot point, since just handling the stuff is a health hazard, and there is no reason to do so, because it does not cause signal lines in the first place.

Hi Theseus,

Ok, I read your words about toxic problems from mercury.
And I did some checking online to see if there's really anything to worry about.

You will never guess what I found... :shocked: :shocked: :shocked:

This stuff is a major hazard!
It gets into the ground water and runs off into streams and lakes to poison all the plants along the way.
The vapors get into the air and travel wherever the wind carries them. Then any animals who eat the plants
in the contaminated areas will retain the mercury. This means any plants or animals we eat that were in a
contaminated area will add more mercury to our bodies. :nono:

Not only has the European Union outlawed dumping mercury waste, it is a concern all over the world.
Some people are dying from mercury poisoning in their food, while others are living with chronic symptoms
caused by mercury ingestion. I had no idea how dangerous mercury is.
Even the health care industry is taking measures to remove mercury from their inventory of medicines and instruments.
No wonder it is listed as one of the four toxic metals in the RoHS directive.

So assuming we could build a mercury sniffer, we could detect it at long range and follow it´s line (wind or water) untill we find the source ? :shocked:
Don´t this sound as LRL ??

Fred,

I own 3 mercury analyzers. Your idea would work only if the air was totally still and the weather was hot to a certain degree. The correct method of Geochemical prospecting via mercury content in soil is by taking soil samples and heating them up in a closed vessel with a tiny hole in it and then drawing the fumes and pumping them into the analyzer.

[Geo]

The Bowl it retains mercury so that it does not enter in the soil. Vapors are indeed exist and they will come out to outside, other they are very small for a open space, if judging from the size of mercury
Still bowl is placed in region that is not cultivated while at the same time there is not accessible in other people. I believe that this time the environment does not run no danger through of pollution.
However it will be supposed you report also the repercussions from the lead that exists in the matters of soldering for electronic elements? According to Community directive RoHS the lead should be suppressed, other I do not see any industry to stop use it:frown:

The point is; it is ridiculous to mess around with mercury in a bowl, or sealed container of any kind, since it cannot produce signal lines, and thus is of no aid to you as pseudo target.

It can only serve as a health hazard to you, other persons in the area and a toxic pollutant to the environment where you've buried it.

There are no precautions you have taken to prevent any of these things from happening, so no need to attempt to justify your actions. What's done is done! :frown:

I'm just very glad you did this in your country, and not mine.

A little strange logic, if they can absurd bombing, I can absurd poisoning. I do not support such logic.

[nick_f]

I find it hard to believe that there are still people dreaming that LRL detectors actually work (especially people that visit a technical site such as geotech). There is no proof and there will never be. Some people actually make money tricking others into buying these crappy things. But why would anybody else waste time with them?
With a real metal detector it is easy to identify if a piece of metal is present at a decent distance. With a LRL nobody can detect a piece of metal even if it is present at 1mm, 1cm, 10cm, 1m or 10m. How more obvious can it be they simply don't work?

For me is very hard no think in it since I learn of a man who make miracles in this field. The possibility with electronic methods is infinite. So is more hard negate it.

Hi Esteban,

What kind of miracles? If you have ten pots with soil and hide two coins in them, can he or you identify the right pots? Or, even better, is a skeptical person able to use a LRL? In case him/you are not able to specify the right pots, at least you can have a miriad of reasons why it didn't work. If I use a standard metal detector and fail, there can be only one explanation: my detector must be a LRL :D

The world is full of people as John Edwards or other so called psyhics. Many of them are extremely successful and all of them rely on the willingness of the participants to believe in what the psychics have to say. If you are in for some entertainment, check on youtube all the movies with skeptic James Randi, testing various paranormal abilities of people.

Hi Esteban,

Do you have a specific diagram (or block diagram) for one of the LRL you are using? I am sure on this forum there are many people very experienced in electronics and they could evaluate the diagram and provide some feedback about its capability to detect at large ranges.
There are a few teams working on various novel ways to improve classic metal detectors. Would you dare to ask the experts their oppinion about LRL's? For one, I know what Carl believes about LRL...

No kidding? Carl is our best LRL promoter ever. Everything he says is exactly the opposite. All LRLs he coments about are a success:lol:.

You see, we are the LRL tribe. We are like masons, the Iluminatti. Only a few selected. Better it stays like this, honestly.

There are "a man who make miracles in this field" by scamming naive buyers and sell him shameless expensive non-working crappy boxes.

From what I see of who manufactures the majority of LRL products sold on the market, most of those you refer to scamming naive buyers, are also known as Electronic Engineers, and electronic techs.

Me, I'm just a country boy with very little formal education that enjoys Science, and enjoy using what the electronics people make and sell, so I guess I am one of those naive buyers you refer to, since I have spent well over $200,000 buying and testing those shameless, expensive, crappy boxes,built by electronics people. Most have worked for me. I like them.

Exactly, you are the typical "victim" for the people who sell LRL's. You have little education and plenty of money from what I can see :)
Perhaps most LRL's you purchased worked for you in the same way electronic components work for me. I bought heaps of them, but used very few of them. I get pleasure from buying electronic components, I can dream I will build that or the other, but rarely do so. Do I regret this? Not a bit. Do you regret wasting heaps of money for the LRL? Probably not, because you are a collector.

Yes, the metal detectors have their obvious limitations. Unless there is a very large target, most won't find anything over 30 cm. This is all what engineers have been able to build so far. You can give a metal detector to anybody, teach them how to use one, and you can bet even a 5 yo can find a coin under 3cm of soil.
There are people who found a lot more than you found with no LRL or metal detectors. They got in the right place at the right time. Some of them are called thieves :lol:
Anyway, why should I try to convince people against what they enjoy?Somebody's idea of a great holiday is to go in a survival camp and eat earthworms and snakes. Somebody else's may to visit museums and other places in Paris (or go hunting for gold). As long as both of them are happy in the end, mission accomplished.
The only thing is, don't try to convince me that eating earthworms is a pleasant experience :)
And yes, you are right. I am speaking for the less experienced people, who've heard about metal detectors and LRL and they are not decided which ones to buy.

Esteban, I had a look at your diagram. You have a rapid impulse (or pulse) amplifier in there. Does gold emit rapid pulses? When you brign some gold very close to a LRL, can you see the needle going high?
You are right with the capacitor at the output of the pulse amplifier. If you change its value, the needle indication will change. Because a capacitor acts like a shortcircuit for pulses. The larger the value, the less indication on the needle. The electrolytic capacitor is used to separate the DC between stages, and it is ok to stay there. The higher its capacitance, the lower the frequency that can go through.
I am not sure what's inside the equalizer. Is it like an audio equalizer, that amplifies more some frequencies than others? Or is it more like a signal compressor, it provides a pretty constant output for an input signal varying in large limits?
The diagram is not a complete nonsense, as I was expecting. It respects some electronic rules. But if you look deeper into it, you might have a few surprises. If you put a one diode detector followed by a pair of high impedance headphones at the output of the rapid impulse amplifier, you will be able to hear a lot of AM radio broadcast, all stations mixed together.
Conclusion: your device is some sort of a electrical field meter, but instead of finding gold, has more chance of finding transmission towers and radio broadcast stations :) Take your instrument into a Faraday cage, and the needle will go to zero... bring all the gold you've got into the cage, there won't be the slightest change in indication.

Thanks for sharing the circuit diagram with us.

The only thing is, don't try to convince me that eating earthworms is a pleasant experience :)
And yes, you are right. I am speaking for the less experienced people, who've heard about metal detectors and LRL and they are not decided which ones to buy.

We say the same things...
Why you try to convince me that the LRL don't work???
I don't try to convince you that LRL work!!!!

Take your instrument into a Faraday cage, and the needle will go to zero... bring all the gold you've got into the cage, there won't be the slightest change in indication.

Thanks for sharing the circuit diagram with us.

What you did not occupy is that the lrl they do not detect metals, they detect certain conditions that are created by the metals.

Couldn't agree more. They can not detect metals.
They can only detect something called electromagnetic fields and what produces them, which is Transmission Antennas :)

You know for sure that metal detectors are coursed by presence of nearby electromagnetic fields, emmited by power lines, flyback monitors, high efficiency lamps.

How does a LRL prevent the radio signals from overpowering the faint signals of the "certain conditions" due to presence of metals?

I just decided to get more informed about the LRL's. I consider wikipedia a pretty good source of information.

Hi.
I have not the ability to explain how LRL is working !!!!
I say what i have see all these years.
Example...... I have a coin 10cm in the ground, and with a metal detector i locate it. Normal condition....
I remove the coin from the earth and the MD don't detect it... again normal condition. I made the same with a electronic LRL at 2 gold coins. LRL located them. I remove the one coin and i buried it after 2 meters. LRL detected a line from one coin to other..... (not normal condition..), i removed the coins and for 5... 10 minutes LRL detected the same line (from coin to coin).... (not normal condition). I saw it, and i don't know why... or "about why". So (sorry for it), you can't tell me anything about it!!!! Also i don't Know if Esteban saw similar "phenomenon"

Regards:)

So, if you have two gold nuggets, 10 meters apart and you identify the line that links them, you will have to dig like 10 meters in order to find them. In some soils, that could take a whole week of hard work! What is the gold is at 5 meters under the ground? Would you ever dig that deep?
What if you have five gold nuggets in an area of 25 square meters, how will the LRL "tell" you where to search and how deep before you quit?

I suppose you were reading the "spectrums" of the gold coins after you removed them. Or, more likely, you were just getting some radio signal, like the people who do radio fox hunting.

Esteban, I had a look at your diagram. You have a rapid impulse (or pulse) amplifier in there. Does gold emit rapid pulses? When you brign some gold very close to a LRL, can you see the needle going high?
You are right with the capacitor at the output of the pulse amplifier. If you change its value, the needle indication will change. Because a capacitor acts like a shortcircuit for pulses. The larger the value, the less indication on the needle. The electrolytic capacitor is used to separate the DC between stages, and it is ok to stay there. The higher its capacitance, the lower the frequency that can go through.
I am not sure what's inside the equalizer. Is it like an audio equalizer, that amplifies more some frequencies than others? Or is it more like a signal compressor, it provides a pretty constant output for an input signal varying in large limits?
The diagram is not a complete nonsense, as I was expecting. It respects some electronic rules. But if you look deeper into it, you might have a few surprises. If you put a one diode detector followed by a pair of high impedance headphones at the output of the rapid impulse amplifier, you will be able to hear a lot of AM radio broadcast, all stations mixed together.
Conclusion: your device is some sort of a electrical field meter, but instead of finding gold, has more chance of finding transmission towers and radio broadcast stations :) Take your instrument into a Faraday cage, and the needle will go to zero... bring all the gold you've got into the cage, there won't be the slightest change in indication.

This not only detect gold and/or silver, also bronze, coins and cartridge type 7.62 and this last exhibit a big "field" or "phenomenon", I called. But this big "field" or "phenomenon" only is "testable" when the target is buried some years, called by others "halo"? Now, once, walking, I obtain a signal and was in lateral of the antenna, I saw a tree and in the base of it I put the antenna and don't stop the beeps. I found a stainless steel coin, common here. Once I obtain very short beeps and found a lead weight used for fishing. So, lead is a "cold" metal regarding the low level in "creation" of the "phenomenon".

Don't know if detect radio stations, but any device near a tower of radio is influenced by it. Also you can ear AM station in a common voltage regulator... :lol: In the input of my device exist as a kind of filter don't showed here.

[Esteban]

I use separate PCBs for to test different circuits. Audio beeper generator is appart also, and this don't suffer many mods., except the addition of high resistence in serie for to filtrate oxidated nails. The first time I detect in 2 opportunities nails in my patio and I discover that a high resistence in serie with the 100 pF stops detection of oxidated iron items, mainly nails, seems that sharp end of this produced a kind of charge scape and are more easily detectable. But I stop this.

Now, in the joint (via cable) of impulse capturer PCB and equalizer (regulation made between positive and negative of the power source, like a comparator) the detection also occurs with short beeps, this is down the machine. But in front part the beeps are very more insistent.

Maybe must be re-write the wiki info...

Until such time as you can (and want to) offer more details and proof of your claims and assertions; I think the Wiki info on Long Range Locators should stand just the way it is.

[Esteban]

Nicolae, do you're Romanian? I found Romanian electronics magazine with famous Nicolae Ceaucescu in front page, January 1979. You can download hundreds 1970 to 2005 magazine and suplements. There are some MD and other old info, soviet radio schematics, oscilloscopes, thousands circuits, etc.

Yes, in theory.

Yes, in theory.

...and in practice!

[detectoman]

hi estaban thanks very much, for old magazines, here exist! great treasures one embrace

[Esteban]

...and in practice!

Yes, I make a ton!

[WM6]

Yes, I make a ton!



Esteban, with this statement, you just admitted that none of these phenomenal boxes did not work, because if they operated at least one, this would be enough and you would not need a whole ton of crappy boxes.

In Esteban's defense ... you must understand that this is his hobby. In which case he's always looking for improvements, in the same way that we look for advancements in conventional metal detector technology.

Happy New Year for members of forums!

Happy New Year!!!!!:):)
On new year i will see you my New LRL!!!!!
Hahaha:lol:.... i know.... LRL don't work:lol:.
Never mint.... we are a Family HERE!!!!!

Best Regards:)

Happy New Year for who believes in LRL and for who don't believe, perhaps the first man with his instrument he has more opportunity to find a treasure...

[sweatofglory]

Incredible! If only these things actually worked the way you fantasize. There is no specific frequency(?) for mercury. All LRL/MFDs, if accompanied by a list of frequencies for various elements is pure BS. These so-called frequencies were arrived at empirically, and as such are a totally random selection based strictly on the individual operator choosing them. In essence, these frequencies(?) are totally bogus and a complete waste of time and resources.

Mercury does not produce signal lines. Signal lines are a figment of someone's imagination; probably an LRL scam artist salesman.

I can't think of a single good thing about mercury. If you ingest even a small amount of the fumes/vapors, there will be some liver damage. Handling it is also hazardous, since it can enter the body through the skin.

Burying it in the ground, no matter the container, will only serve to pollute the earth and the water supply in the immediate area.

Back in the late 1970s, we were still etching some printed circuit boards using ammonium persulfate with a few drops per gallon of mercury catalyst, and the mercury catalyst was not actual mercury, but a derivative of mercury. Even that mixture was banned (in the early 80s) from use, and boards were etched with ferric-chloride to eliminate any trace of or use of mercury derivatives.

The use of mercury has never aided anyone in uncovering or locating treasures. Fooling around with it can only cause you harm and damage the environment. :nono:
