Default MD as long distance

How a search head of MD can work as long distance. Coil is type pinpointing.

The max. distance was a coin at 70 m. in inland.

Question MD as long distance

Since we are on the subject of long distance. Tommorrow I am picking up a Fisher Gemini-3 for $50 dollars . Only thing thats missing is the connecting piece or arm that goes between the two boxes - "transmit and recieve". The unit makes noise and has 8 AA batteries for each box and No rust inside. I guess it runs around 60 to 70 khz. Anyway I just wanted to know if the arm is metal , like aluminum or a composite material. I might make a "makeshift PVC assembly" if i cant find the factory brackets. I am not sure on a price of a new one but I heard there over $500.00 ??? And how deep they go I have no Idea !! This will be my first 2-box for my collection . Any comments let me know , Thank-You Eugene

Hi Esteban .
Can you discriminate with your long distance detector?????
Who is the behavior in rust objects???????

Hi

This only detects silver, gold and copper-bronze, non ferrous objects since the coil is adjusted only for non ferrous. Aluminium cans no detect.

For small objects has not depth, but yes for big items. Object must be in soil since X time.

I just posted some of my experiences in "Testing and Comparing.." thread.
What you saying here is just against my claims. So i am very interested in that subject. Can you describe a bit more that device?
Best regards Esteban!

hello esteban:

have you the diagrams of these locator? what sistem or components inside,
hola esteban saludos, dime tienes tu mas informes acerca del circuito de ese detector, y dime si esos 14 mts solo los logra en aire, o cuanto puede profundizar, dime por favor a que frecuencia logra eso, y que marca o procedencia es
te mando un abrazo y espera correo despues pues tengo la pc en el taller y ahorita solo entro brevemente, y con esta pc prestada

ok gracias por compartirnos

Hi post this, because you know detector based on coils. In this case, as coils no touch soil, no suffer capacitance or mineralization. Variation of few hertz in coils is converted in audio, so items can be detectable at certain distance, and this coil system is accuracy, but more slow than antenna. Frequency in order 300 Khz tends to detect cigarette paper, but good points is near 150 kHz. You need this semi-high frequency for to obtain variations in some hertz. I built one in 59 kHz very stable based in off-resonance (this is good for long distance and need only one coil). Other type can be achieved. Here antenna type (I with beard and cigarette -Ivconic: I leave it 7 years ago!!!)

Default There is merit to this device

The only part I have trouble with is detecting paper,but far as metal in soil causing a shift in the frequency at that point seems possible. You'd have to have an extremely high Q resonant coil to detect a shift in the natural electromagnetic fields. Considering that metal in the earth disturbs the matrix which is a RLC circuit to begin with it sounds very interesting. I know Esteban has been experimenting constantly for 30 years or so.
With induced polarization you get a response from dissmenated ore because of the conducting grains are in contact with one another but you also get a response from sulfides,some oxides and clay.

For those who are interested go to the US Patent Server and do a number search on patent 6,414,492. Then starting with the listed patents at 1985, go towards the present. In particular interest are:4,507,611-4,686,475-4,841,250 and 5,148,110.

C'mon...never mind project and principles...I can live even with most crazy ideas.....but just pay attention on Esteban's claim above...!!!!????

Even it was 70cm, it would be impossible....but 70m !!!!????
I dont have words just

If you put effort in it, you can. As Randy said, a good coil is necessary. Also adjust the resonance the max. possible, at pF range. I use off-resonance type. I use capacitance box and adjust the pF range with trimmer.

Robert, some LD infos and others (a very minimal part). Do you can follow the path? Sometimes, do you work in it?

Hi ESTEBAN,
kindly enlarge the pictures you posted, I am willing to build it and experience what you have experienced in the field. I am serious ok.

Default Robert consider this

Robert,

What I'm thinking is the distance that VLF magnetotellics can detect a body of ore. Granted the ultra-low frequency gives you deep skin effect and only good for a very large deposit. Now scale the frequency up and shrink the size of the object accordinly and now it doesn't seem difficult. Study up on magnetotellics,think about the scaling factor and let me know your thoughts.

Randy

Sorry, Esteban, but what you are claiming does not align with physical possibility. Unless there is independent collaboration, I will have to assume that these devices are essentially the same as all the other LRLs out there: non-working wish devices. And I have personally owned, used, and tested just about everything the LRL world has put out, from chemical loads, to MFD, to ionic... none of it has ever even remotely come close to working. Nor have any of the technological claims.

"Here antenna type..."

By chance, was this device mounted on a swivel handle?

I agree with Aulook; can you enlarge posted photos? So we can take part in and follow your ideas...Otherwise, you just cant expect me to judge about your project according thumbnails....i hardly can see those?
If you are sure in your claims....let us (others) to see ist it correct or not...
"Let us in your world..." !

Ι Think Esteban should not publish his ideas. Everyone should try on his. Sorry for the recommendation, but this is the truth

No, is pure electronic. Microvoltmeter type.

The most of the devices show in small figures are electronic, EXCEPT some LRL rods. All us experiment with it. Chemical type nothing to do with chemical load of the LRL rods, is based on a kind of "galvanization at distance via high voltage". I don't know if the scientist walk with this kind of devices for to obtain information from buried objects.

Justly I post coil type because the most part here are associate with the well-known coil type. Yes, this ALSO works as long distance.

I've no idea what you're trying to say here.

Although I respect your efforts, it is unlikely that anyone will believe your claims, unless you can post a design that is claimed to work AND can be duplicated by others.
How about it?

What!? Than why posting any post here? Why claiming such brave claims?
Why bugging everybody here?

Say...arent you "mineorogreece"? Ha Andreas? Old "friend" with brand new nick? Hungs brother in arms?

Esteban i took closer look at you funny thumbnails.....all nonsences!
Sorry....i do not intend to offend you but all of those are pure nonsences...
It is shame that you wasted so many years torturing yourself with "abracadabra" nonsences..!

Like i said this thread not supposed to treat seriously at all!
Regards!

No Robert. I am not mineorogreece, I live in Athens and my name is Andreas Christi. If you want come in my country for hollidays stay free of charge, I can you entertain, and see with your eyes truth. Simply I believe, when somebody tries achieves something, genuine or dream, we should not make attack , when we know very well, that here in the more, want something…. no only for personal use, but for commercial exploitation. This is don't like me. There are private e-mails for information. This is better
best regards

Hi robert . I know Andreas very well. He is not "mineorigreece". He is a very good electronic engineer.

hello Forum ,
The world of treasure searcher is full of shift brain people like Esteban to confirm the detection of a coin at 70 meters .. I think now it is a very rich man because with a aparatus like that you can win every challenge in the world....
Here in Mexico you have a prize like Carl of 25000 $ Dlls US if you detect a coin at 10 meters (not 70) distance with pseudo detector,OK

Yes - I think Esteban must be a very rich man.
He can travel the world collecting all the prize money.
