Is there any way?

[Qiaozhi]

unfortunately who came to test the farm didn't give any 3D plote

So how do you know there is really something buried there?

Hi Dear Qiaozhi,

pardon me for delayed reply, I was in a TH trip without any success! for answering your question, there is some ancient map and etc for there but finally I wish there be!

what do you think about this book? http://www.friese-electronic.de/ortu...echnik-lf-vlf/

he said his product can detect 24cm diameter pipe in several meters. does it right?

Other than GPR, that is the only way to find such an object ... provided you have a strong enough LF broadcast transmitter not too far away. If not, you'll have to make one, as this principle depends upon the far field LF transmission.

Hi wubian,

there is a big difference in detection between a long and 25cm diameter metal pipe several meters below and a single object even if it has a size of 50x50cm.
Such a pipe works like a huge underground antenna and "concentrates" the long-wave energy-fields, while such a single cache may not react at all on it,
depending how well the metal and moisture is isolated from the soil and from a larger distance this wooden or other package stuff around an object
can be seen like cavity depending on how strong is the mineralization of the soil which weakens the metals signal, especially if its very deep.

And the specific weight of pure gold is very high, 19,6966 kg per 10cm cube while the same amount of water weights just 1kg.
The electric flow through fine gold has almost no restrictions and is: 45,5 · 10⁶ A/(V · m)
You can detect even a half kilo of gold 2meter deep but in that case it has to be a ca. 70x70cm large foil.

If the treasure chest contains usual gold-bars and there is piled one bar over the other the seen from above total metal surface area could be
just 30 x 30 cm and in this case you need a sensitive detector with 1m coil and at maximum 1,5m depth to find it.

I think the question is very legitimate:
Who buries this stuff so extremly deep and how you can be shure if this is not a lost or wrong track?

You may have a changes if it is really 6meters deep if you drill some test holes and lower special shaped metal-detection coils down there.
But in that case you must drill at minimum every 1meter such a hole which only is useful if you know pretty exactly the right location.

With a large excavator you also could bury deep trenches parallel each 5meters but in that case you must first reduce the hotspot-searchsite to an ca. 50x50meter area.

If you are very optimistical you can hope the treasure is buried just 2meters deep and you can reach it with a detector that uses a 1-2m coil.
You never know, especially in the area of treasure-hunting even the most unbelievable occurances are possible. And if you are interested in further
treasure-hunting, such an 1-2m detector would be a good investment anyway.

There is no simple solution in sight in your complicated case but on the other hand that way you have a much more interesting challenge.

Today I have readed in a gold- and treasurehunting book something about a person which appearantly could "feel" metal.
I have no idea how serious and how reliable was this info - seems this has happened already 100 years ago.
Most persons who claim such stuff, same with finding water-veins by dowsing rods, don't have such super-natural and mystical abilities.
This area touches already the highly doubtful occult, esoterical, religious, fortune tellers and pseudo-mystical scenes.
As example there exists really alot gypsy-women who claim to have the gift of fortune-telling or oracle-interpreting.
Often this is just for fun entertainment while having tee and cake together but some are totally shure about their talents.
Personally I think finding a person who has really super-natural powers will be a one in a million task.
But because of the high fortune of the hidden gold you may find such persons who wanna try their luck or "psychic gifts" at this location.
You just have to be careful that such mystical detection results don't lead to high amounts of wasted money for hotels, fees, test-digging holes etc.

Good luck and keep us informed about your next plans and advantages.

Several weeks ago I tried to find a copy of this book, but was unable to locate one. I even sent an email to the author, and did not get a response.

Hi wubian,

Hi 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. I really appreciate your willingness to assist.

I meet some of this mystical person, they just can detect metal up to 3-5 cm!!!

Hi Dear Qiaozhi,

I sent an email for him and if he answer me before you, may be I can take this book and send it for you. you knowledge is more than me!

Saw an impressive demonstration of a commercial GPR on TV last week. Can't remember why but they were looking for an old cellar from a building that no long exists. On the LCD screen not only could you see the cellar but you could see the disturbance of the ground above it. If I remember correctly that was 2 meters down and then the height of the cellar.

Dear Davor,

have you this book http://www.friese-electronic.de/ortu...echnik-lf-vlf/ ?

[Davor]

Yes, but I'm not sharing

[wubian]

Yes, but I'm not sharing

Hi Dear Davor,

It's ok, could I ask you some question about this book and its content? If yes:

please let me know that does this book contain every (all) documentation about how to build that metal locator or not?

Thank you
Regards

[Davor]

It does. There are several projects centred around the concept of seeking deep buried objects by means of far field transmission. If you look around, you'll find even some professional equipment that does this very thing, just look in google by "cable locator".
All the projects in the book are supplied with schematics of electronics needed, and the PCB layouts, and they are not too complicated. You won't find any of such approaches described on this forum unfortunately, so your best bet is the book.

There are some constraints though. If you do not have a strong LF transmitter near by, or even a stronger one far away, you'll have to make your own transmitter. In Germany there are several such transmitters, such as time standards and such. LORAN-C is killed in US, and most probably other LF transmissions will follow it's demise, so it is likely that you'll need to make your own transmitter as well. Some professional equipment vendors offer such transmitters along with their cable locators.

The other constraint may be language, as the book is in German.

Hello

does any body know how can I detect the tunnels? does it possible with magnetometer or proton magnetometer? if yes, please let me know is there any good references on how to build it? I think I saw a book about it in the past but I'm not sure.

Thank you so much.

Hi wubian,

you may read the following thread first, started by Davor a half year ago and called: "LF Project"
http://www.geotech1.com/forums/showt...198-LF-project

I have no idea how far is Davor with this project at the moment.


You're looking now for the most deep going detector that exists like many others do,
and of course it should cost not those astronomical sums 10.000 bucks and upwards.
This motivitation and intention is understandable but this can end for you in "trial and error" only because
the more deep the more complicated or "fainting" or hard interpretable signals you will get.

Perhaps your best bet is to buy such Long Wave based "cable locator", some device based on visual magnetometer (Laptop or smartphone screen output)
(of course the magnetometer will not detect very good the gold, but perhaps the cavity or ground-anomalies at this location).
The more simple and easy method would be a Pulse Induction detector with 1-2m coil or last but not least one of those 2box detectors or
the Jeohunter oder DeepHunter including 1m coil because it also can detect very deep and cavity, too.

Start building such LW-far field detector including transmitter and tuning it to good sensitivity can be a complicated work.

Shure it looks promising and highly luctrative geting info and electronic parts almost for "free" and create such "ultra deep super detector"
including some help from the electronical talented users of this forum but you could end up with not at all working homebrew-stuff,
wasting enourmous amounts of time and finally you will end by deciding to buy some really working, anyway.

You may give it a try but don't expect miracles from such "special receivers".
btw. there exists another uncommon method you can try: use an infrared-filter-lens if you have a digicam
and take some pictures of the region at different daytimes. Sometimes different underground structures will cause other temperature values.

And for cavity even seismic feedback is creatable by sending low audio-waves into the ground. Special detection-devices exists for this method, too.


Too bad we don't have any gravitation-detectors so far which reacts on high concentrated heavy objects "close nearby".
20kg of gold at 6m distance could give a good contrast picture compared with the surrounding relativ "lightweight" soil.


Last but not least someone could dig some horizontal tunnel-systems. Don't laugh , some bank-robbers came from 50 or 100m away
to the basement-treasure-rooms full of money and gold. That way it happended in Brazil and in Berlin.
But first you really need precise information, it's no fun if your tunnel misses the treasure location by just 1-2meters!

Hello Dear Davor,


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,

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 ...?

Thank you again
Regards
