How to construct a Test area for LRLs

[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

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.

The Au-198 at his precession toHg-198 emits photons of energy ~0,41MeV

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!

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

I am sure for it!!!!!
You have not problem for the destruction of the Yugoslavia.... Iraq... Afganistan.... etc, because these countries are not yours

I have no idea what your point is.

If you are mad at me for pointing out your flagrant mis-use of mercury. So be it. But why the mention of these other countries? No reason to make this a political issue.... is there?

You're very glad if Geo don't make this "not very invasive" test area in your country, but Geo also will be very glad is your country don't use other countries as test areas of bombs, for example...

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

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

Fully agreed, Esteban.

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

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.

Actually, even better, you can check the movie about detecting metals (zinc) using the dowsing method.

Electronic methods is not the same than dowsing methods.

Your reference is maybe about dowsing...

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...
