Is there any way?

[wubian]

Hi wubian,

Dear Funfinder,

I thank you for taking time out to answer my question. I am sure that you are really busy and I appreciate you taking the time to respond personally to me,

after some thinking I found that I have to change my approach. if the treasure is more deeper that 3-4 meters, there must be a tunnel and room. so for 3-4 meter depth I can use PI with big coil as you said or two box ( I already have one 2box). so I think it is not important if my device cant detect more than 3-4 meters for big metal like a chest.

also if there is a treasure deeper than 4 meters I guess there might be a tunnel or room, and for finding this treasure I don't need ultra deep MD I dont know if this approach is good or correct or not!?

based on my new approach, I need a device for locating / detecting room and tunnel. so does it possible with magnetometer or proton magnetometer? I also almost finished my ERM project but don't test it yet.

thank you again for your Realistic comments, I really appreciate your willingness to assist.

Regards

...I thinking and searching some days about your post and now I have to more question:

1) on technical view point, does it possible for me to build such transmitter by my own?
2) does this device able to locate ferromagnetic metal too or just magnetic like iron ...?

1) such transmitter is incredibly simple, but it's antenna is not. In case you are detecting near your own house, you could make a ground loop that encircles the inside of your fence, and hook a simple, but powerful oscillator to it. E.g. you'll need 1 turn of 2mm diameter wire going around a 10x10m square (or any other shape) making a total of 40m wire, resulting in a ~67uH coil of resistance about 0.3 ohm and Q factor of over 40 at 30kHz. Just about any oscillator could do.

2) this device will detect any kind of discontinuity in homogeneous soil, iron, coloured metal, or cavity (e.g. a tunnel, or a plastic gas pipe etc.)

Dear Davor,

I thank you so much for taking time out to answer my question. I am sure that you are really busy and I appreciate you taking the time to respond personally to me,

all yeasterday I was waiting for your reply. I have just one more question, ( I am Excited after reading your reply, please pardon me if I ask many question and take your time!), please let me know, if we have a 50X50X50 cm chest with metal inside it, does this device can detect it in dept of 4-5 meter?

and a very important question for me, you said it can locate cavity, you know man this is really what I want , so please let me know does this device able to locate a tunnel with 1.5-2m diameter in depth of 4 meters?

again, Thank you so much Dear Davor,
Regards

I did not try any of these devices yet, but from the purpose and specifications of this family machines - yes, I'm quite confident this principle will find your chest. They are made to find large objects and caves deep under ground. Especially if you have some strong LF transmitter near by. They won't find you a single coin though, but a big cache - yes.

So, do you have a strong LF transmitter near by? Can you scan a LF band for strong transmissions? If so, just build your machine for that frequency.

You are too polite for a westerner. Where are you from?

Dear Davor,

Thank you for your response to my inquiry. I appreciate the information you have provided me with and I appreciate the prompt reply.

I am really happy after reading your post and the information you gave me.
now I'm looking for a copy of that books and I have a plan to build and test these devices. about you last comment, I am very thankful for your compliment, I am Persian my Dear friend .

You have really helped me before and I think I need it again. Thanks again for your time.

Hi wubian,

thx you for your friendly and thankful words, I was indeed very busy because I couldn't waste the final treasure hunting days this year before winter breaks into Europe.
I have had a treasure-hunting maraton trip the last 14 days with only 1 day pause!


Now to your questions:
> I dont know if this approach is good or correct or not!?

Shure it would be better for detection if the treasure is located at an underground room but:
If the area is sandstone or desert sand the cavity can be very hard to find AND how good is your information that there is such room at all?

As Davor said already, it is important that the ground consists of homogenous material - in other words: the mineralization level should be everywhere the same.
Otherwise you can get misleading distortions the more heavy the deeper it goes.

But if its sandstone and lightweight nonmineralic desert the metal-detection would be pretty deep almost like if it was in air.
Of course if the ceiling of the underground room was made of heavy stones this would weaken metal and cavity detection.

coilsizes: it is no problem to detect an iron door 1,5m x 70cm with a 45cm coil up to 3 meter distance in air with non-motion or PI detector.
But depending on the soil this can be reduced up to 50% if buried.
So having a fair chance to detect a buried 1x1meter metal object at 3m depth an 1 meter coil is a must have!

Shure you could be lucky that the cave or room with the treasure is much larger than that but still there must be enough contrast - if seen vertically from above -
in total with the surrounding ground and the deeper the room is, the less detectable values you can get, standing on the surface of such a complex.

One possibility for you, wubian, would be to rent a modern magnetometer with display.
Of course it depends how sensitive are the sensors, how much distance they have, how "clean" is the soil, how exact is done the measurement (the area scan).
The results on the screen will give you an impression how hard to interpret the whole scenario can be. You will see here a more blue shadow and here a red spot
or like little lakes of colored areas.

And I would say if you can't reduce the whole hunting area to a 40 x 40 meters size the chance will be very low.


Wubian, you are from Persia, from Iran?! This is very interesting country and it contains many old gold treasures. But the treasure-hunt could be restricted by law
so you have to know what you do or better don't. You should have a good plan how large is your budget for investment and what you can risk.
The treasure you are describing seems to be very hard to find and I doubt you will have a chance with cheap or selfbuilt equipment.
Perhaps it would be a good idea if you look for partners, investors or rich people who have a big and special interest for such adventurous challenges.
If you do this completly on your own the chances to fail are very high. Some people wasted their half life for such hard to find treasures and found nothing.

Just a few kilometers where I live the Nazi-Gold could be hidden - as they say - but how much is truth and what is rumors and pure wishthinking or old romantic stories?

And we have those people here, full of interest for that gold-treasure but finding nothing than rusty 2nd worldwar remainings since many many years!
There hope lies in the next, better and even better or new technology detector but the area is unbelievable huge and without shure information nothing can help them.


If I was you, wubian, and if the area is just ca. 100 x 100 meters (yes, I can deal with such large hunting areas, I do it all the time) I would try to get or built
a non-motion-circuit detector with 2meter coil that is able to detect in both directions - metal and cavity. Minimum 1,5 meter coil if its below 3,5 meters or even at 5 meter.
But only if the information is 100% true and save. It can take already 1 month if you only investigate a 20x20 meter square each day of such area (of such a, for my circumstances, "small" location).

20x20meters means already 400 squaremeters where each of them must be carefully analyzed within one day.


> 50X50X50 cm chest with metal inside it, does this device can detect it in dept of 4-5 meter?

If you built such device by your own for shure it will not detect it. Because you need a very high stability and as best a computer screen output so you exactly know at what point of the area what signal-strenght or distortion you got. The additional transmitter also needs good stability.


We have bad luck so far if it comes to depths beyond 5 meters and if the object is relative small.
Someone has to invent a total new technology for this kind of tasks.

I'm thinking about very energetic parallel going EM-waves at relative short wave-lenght where the transmission circuit directly detects if something changes the usual energy-level of this almost "straight field". Not induction balance but more a kind of indirect feedback of the complete surounding energy-field. Something like autodetection if the transmitter needs more energy because there is something in the ground that changes the normal energy-level. A second method would be high energetic long- to shortwaves combined with a much larger distance - comparable with a 5 meter large two-box system that works with very high power.


But forget about this for now, we haven't invented and built this kind of special tools so far.


At the moment you can look for a detector with 1,5-2m coil, try to get some computerized modern magnetometer for rent and collect more important information about the treasure, its location, when was it buried and who may know more about it. And one of the most simple methods could be if you investigate on a very professional basis the ground and the whole area there - looking for clues where something could have been changed man-made, by machines etc. If you are lucky you may find clues and hints directly at the surface with an usual metal detector or by changed patterns compared with the surrounding area.

Is there a larger city where you live and can you import all kind of special devices without fear or prohibition? You will need some good support and special technical stuff. Per instance to open old kurgans in Kazakhstan and Azerbaijan (perhaps just some 100km in the north of you) they have had a whole company of diggers and also military security forces to protect the area. The gold-gifts in those graves have been at around 10m meters depht not far from the center of the 30m large and 10m high grave hill.
see: http://en.wikipedia.org/wiki/Kurgan

The most part only was digging and almost anything just by hand. The metal detector only came in use when they have opened already the 2x2meter chambers.

And don't forget:
If you don't see a chance to find this gold-treasure by your own or with your available equipment, there is always the way that you could sell your information to persons who have better possibilities or machines than you have. That way not everything is lost as if it would be if you can't reach it by your own and with your abilities. Perhaps you can get a good deal with the military commander in your area and he gives you a good reward for your information and technical assisting support. You even could lead and supervise the whole excavation if you have the best treasure-hunting skill there. Or you can leave it be and wait for 10 years until better circumstance are occuring if the whole project is not very promising at the moment. So please tell us about your next plans and:

Good luck my friend.
