Devices for searching for anomalous zones. Georadar for finding treasures and coins

It is necessary, it is very necessary, Dear search engines, to reach a new progressive level of search, as there are very few “not knocked out” places left.

More and more often the thought comes to my mind to buy ground penetrating radar for finding treasures and coins in order to find several dozen coins, or even a whole treasure, without problems on a field dug up by search engines.

Only one circumstance prevents me from acquiring a “dream” - this is the price of a georadar, since the cost of it, even the cheapest (but to the best of efficiency, I do not take Chinese fakes into account) starts at 6-7 thousand dollars (for example, the excellent Russian device “Loza M ”).

By the way, watching the prices in online stores, I see and am glad that they are slowly getting cheaper. Well, our time will come, but for now I’m watching with “black envy” the lucky ones who were very lucky in finding and selling coins, and they saved up and purchased this powerful device (or risked taking it on credit).

So, what is a "geo-radar"? For those who are not “in the know”, I will briefly explain ...
This is a very powerful device for sounding (transmission, and displaying a cross-sectional image on a monitor): earth, water, and other media, and it can search not only for metals at a very great depth (up to 25 meters), but also voids in the ground , to see the structure of the mixing of soil layers (a very important parameter for a treasure hunter), i.e. if someone dug this piece of land, well, for example, at a depth of 2 meters, then it is quite possible to find something worthwhile, even if a thousand years have passed.

Its scope is very extensive: archeology, search for underground tunnels and communications in construction, they are looking for oil and gas deposits, metal deposits and much more, as long as your imagination lasts.

The principle of operation of the georadar. Which model to choose to search

Georadar consists of three main blocks: antennas (transmitting and receiving), receiving unit (usually a laptop monitor), and the main part - optical and electrical converters.

Working with this complex device requires a lot of skill and a lot of patience. But if you have firmly decided to work (search) effectively with it, and even more so have invested a lot of money in its purchase, then of course, over time, it will “submit” to you.

What is the main thing in working with him we need to know? Firstly, of the two antennas that come with the kit, to search for coins and treasures, we will be interested only in high-frequency (frequency 900-1700 MHz), they “see” not deep (up to two meters), but their resolution is very high .

Some models do not see less than a metal object 10 by 10 cm, the creators of others promise “visibility” of a large coin with a device, all this needs to be studied in detail in the instructions, and in practice, and of course, to compare individual devices (some are suitable for searching for coins, others are just do not see).

If you intend to find an underground passage, some kind of deep well, voids, deposits, then use a low-frequency antenna (frequency 25-150 MHz), you will not see small objects, and scan large voids at a depth of up to 25 meters very easily.

Each type of search has its own program, so from the very beginning you need to determine the type of search, and choose the right one.

On some expensive radars, a converter is installed that formats scans into a three-dimensional image, it is easier to work with it, and the cut of the earth is visible “at a glance”. It is not available on less expensive ones, and you have to analyze scans for a long time, and figure out what could be there.

I heard now there is a paid training in working with a georadar, those who wish can “dig up” information on the Internet. That's all .

The purpose of this article is simply in general terms get acquainted with this device, learn the principle and efficiency of work.

In the following articles, we will separately give characteristics to radar models, point out their advantages and disadvantages, how to work with it, and where to buy (add our site to your bookmarks and stay tuned for new articles).

We note right away that the actual treasures are not searched for by any equipment. You can not set the parameters of the alleged pile of gold coins or precious stones. Therefore, all searches are performed by indirect signs, for example, by the resistance of the object, by its electromagnetic or magnetic properties. From this “stove” both geophysicists and treasure hunters have to dance (it has been noticed that modern treasure hunters become geophysicists to a certain extent, and geophysicists often become treasure hunters).
Let's take an ordinary soil metal detector. Strictly speaking, this is not a metal detector, but a finder of medium resistance anomalies. If the resistance is low enough - there will be a signal that “there is an anomaly in conduction!”. That is why “phantom” signals are often encountered - there is no metal, but the metal detector reacts. So, for some reason, the soil has a very low resistance. The same applies to any other equipment - magnetometers are not looking for iron, but for magnetization anomalies. And ground penetrating radars are looking for conductivity anomalies, not gold-silver-underground passages. In other words, all searches are conducted not on direct, but on indirect grounds.
For this reason, let's consider what additional indirect signs can help the search for the desired object.
Electrical resistance. Due to the prevalence of manual ground metal detectors, this parameter is known to all archaeologists - both professional and amateur. According to the anomalies of resistance, there are coins and treasures in the uppermost layer of soil. But what to do if the treasure is at a depth of 50, 80 centimeters, or deeper - a meter, two, three? We already know that the resolution of any equipment decreases with increasing distance from the sensor to the object (see the article “Instrument Accuracy and Resolution”). And even a pot full of gold coins at a depth of 1.5-2 meters will not be detected either by an ordinary metal detector or by a “deep” one. And here we take a closer look at the object. Yes, the pot (head over heels, cast iron, etc.) is small. But in order to bury it, a man dug a hole. And at the same time, the structure of the soil was disturbed - and it is always horizontally layered, such is the geological feature of the sedimentary cover of loose rocks into which something can be buried. And the transverse size of this hole is the larger, the deeper it is. After the treasure was lowered into the pit, the man, of course, buried it, trampled the ground, perhaps even somehow disguised it. But it is no longer possible to restore the soil structure in this pit - the layers of rocks are hopelessly mixed, and the resistance of this area has changed! As a result, we have a wonderful an indirect sign is a low-amplitude negative resistance anomaly above the well.

Fig.1 Model of the geoelectric section: reduced resistance above the pit and increased resistance above the buried foundation.

And if hundreds, even thousands of years pass, the conductivity anomaly will remain. Such an anomaly will not be detected by any metal detector - metal detectors are “sharpened” for a different level of resistance drop, much sharper, corresponding to the difference in resistance between metal and ground. But equipment capable of detecting minor conductivity anomalies has long existed in exploration geophysics. Some types of this equipment have been successfully modified to solve archaeological problems. First of all, these are archaeological resistance meters (the English device RM15 and the domestic "Electroprobe") and ground penetrating radars(see section "" and "").
The resistance meter is a frame with electrodes (Fig. 2), between which the soil resistance is measured.

Fig.2. Resistance meter RM15. Tensioned cords are visible, indicating the profiles of a uniform network.

Measurements are made point by point, along pre-selected routes. Using this method, you can perform simple search work on a specific area, when the task is set something like this: “They say my great-grandfather buried a pot of gold in his area, presumably in this garden or in that garden over there.” Or: “The estate was burned by the owners, who fled with a small hand luggage, having buried larger valuables in advance (silver, crockery, etc.)”.

Walking with electric probe on the indicated sites with a distance between measurement points of approximately 0.5 meters, it will be possible with a high degree the probability of telling where a hole was ever dug here, how deep and how wide. In principle, the resistance method, depending on the distance between the electrodes, makes it easy to penetrate to depths of tens and even hundreds of meters, but archaeological equipment is oriented only to depths of up to 2-3 meters. Deeper its resolution drops sharply, and there are practically no archaeological objects at these depths.

Another problem solved by the method of resistance, from classical archeology: a specific site is given, and it should be found out whether there are buried foundations underground, the remains of walls, voids, underground passages. And if so, how are they located?

With the help of the same Electroprobe” or RM15, we survey the site using a pre-set network of profiles (see section “ ”). Then a map of the electrical resistance of the site is built (Fig. 4), according to which archaeologists plan further excavations.
Field work with georadar is not much different from the application of the resistance method (see Fig. 3) - the same movement along profiles during areal surveys or along arbitrary routes during searches.

Fig.3. Working with georadar

The results are also presented in the form of maps of the electrical resistance of the section or in the form of three-dimensional sections (Fig. 4.5).

Fig.4. Map based on the results of areal work with an electric probe.

However, georadar has certain advantages - firstly, georadar gives a more accurate depth determination than the resistivity method. Secondly, under certain favorable conditions, the georadar is able to distinguish individual small (from 10-15 cm in size) objects at depths up to 50-80 cm. The disadvantages of the georadar are its high cost and the need for highly qualified user (see article ""). As well as the resistance method, GPR survey reveals buried pits, foundations, and other structures. The depth at which the georadar shows an acceptable resolution does not exceed 1.5 meters (usually 50-80 cm). On the great depths, of course, the resolution drops sharply, and the structures associated with human activity are obscured by geological formations. Let us pay attention to how in Fig. 5 the detail of the section changes sharply with depth - already at a depth of 2 meters only objects with a size of at least 1 meter are visible.

And let's go back to treasure hunt. Of course, the more we know about an object, the greater the chance of finding it. Now, if it is known, for example, that something is hidden in an underground passage or in the cellar of a house that was destroyed and completely disappeared from the face of the earth, then this is already a plus! The fact is that the walls of buildings, foundations and voids (and any combination of them) also give conductivity anomalies, but not in a positive direction, as is the case with pits or metals, but in a negative direction: these are objects with high resistance (Fig. 1 ). And such objects are confidently distinguished by the method of resistance or georadar. Thus, we have another stable indirect sign - an anomalously high resistance of the object.
Another group of indirect signs is associated with the magnetic properties of the medium:
Magnetization.
They have magnetization in varying degrees all geological rocks - both rocky and loose, sedimentary. But there are objects whose magnetization is hundreds and thousands of times higher than the magnetization of rocks - these are, in 99.9% of cases, products of human activity. The exceptions are meteorites (which in themselves are of exploration interest) and iron ore deposits, which, of course, are very rare.

The magnetic field has a remarkable property: it decays in proportion to the 3rd power of the distance between measuring instrument and the source of the anomaly, and the electromagnetic field is proportional to the 6th degree.
In other words, magnetic anomalies caused by any objects decay 1000 times slower than the electromagnetic field signal used in metal detectors and ground penetrating radars, reflected from a conductive object. This property makes magnetic research one of the most profound methods used in archeology. At searching for iron objects no other method can be compared with magnetic prospecting in terms of efficiency. Accumulations of ceramics and burnt wood are also well detected by magnetometers. But the method also has a significant limitation - no metals, except for iron, have any noticeable magnetization, and therefore are not objects for magnetic exploration.

Let's get back to indirect search features. So, if we have a clearly defined magnetic anomaly of the appropriate size and intensity and see that the object is located at the expected depth (methods for determining the depth of the object are described in the section ""), then with a high probability we can say that we have found what we were looking for! Everything is clear and simple here: magnetic exploration does not give "phantom" anomalies - the source is always obvious. Another interesting effect has been observed in magnetic fields. If a part of this rock is removed from geological rocks that have a certain magnetization, then a low-intensity negative magnetic anomaly appears at this place, the so-called. "deficit of magnetic masses". Due to this effect, in some cases, underground passages and voids can be detected, which will be fixed on the surface as low-intensity negative anomalies. Examples of detection of such objects are known, and some are even presented on the Internet. Thus, low-intensity negative anomalies can also be an indirect sign of the desired object.

Summing up, we can say the following: the most effective for searches will be the use of not just one method, as is usually the case, but a certain rational set of methods, each of which will make its contribution to the common cause. In exploration geophysics, there is a whole section dealing with the integration of methods to solve the most different tasks. Foreign archaeologists always use a set of methods - this approach allows you to quickly and cost-effectively solve the tasks. For this reason, we considered it useful to propose a set of methods that solve the most typical search and archaeological problems in the article “Electrical prospecting in archeology”.

The Earth is a kind of huge crystal in the form of a dodecahedron (figures of 12 pentagons) with edges, nodes and geo-energy lines of force connecting them. To date, numerous lattice structures with cells of various shapes and sizes have been discovered: rectangular (E. Hartman, Z. Wittmann), diagonal (M. Curry, Alberta), etc. These are the so-called “global geoenergy grids”.

The "lattice grids" of the Earth are field formations in the form of lines of force, planes and energy nodes. They arose as a result of a complex interaction of numerous geophysical factors (in particular, piezoelectric and magnetohydrodynamic processes in the earth's crust) and cosmic processes. It turns out that a thin energy network is thrown over the globe, similar to a grid of conditional lines of meridians and parallels, the only difference is that it really exists and is perceived in various forms by all living organisms.

In the bands of the grids, accumulations of electrons, ions, and active radicals of gas molecules are recorded. And at the intersections of the strips, local zones are formed ( geopathic zones) in the form of spots, a high concentration of radiation in which is considered harmful to humans.

If we consider the spatial structure of the grids, then it is a series of separate intersecting vertical “walls" (of different widths for different grids), at the intersections (nodes) of which compacted “pillars” are formed. The most studied is the global rectangular coordinate grid of E. Hartman (G- network) and M. Curry's diagonal grid (D-net) They are an integral component of our habitat.

Rectangular Hartman mesh (G-network)called “global”, or “general”, since it covers the entire earth’s surface and has a lattice structure of a fairly regular shape. The grid is an alternating series of parallel strips (walls) about 20 cm wide (from 19 to 27 cm). The radiation of the strips is inhomogeneous : it consists of a primary part (width 2...3 cm) with pronounced electromagnetic properties and a secondary part formed by radiations of various fields, active radicals of gas molecules covering the primary part in the form of a kind of "fur coat".

The Hartman grid is oriented to the cardinal points (north - south, east - west). Each of its cells is represented by two stripes: shorter (from 2.1 to 1.8 m, 2 m on average) in the north-south direction and longer (from 2.25 to 2.6 m, 2.5 m on average). ) in an east-west direction. Such a rectangular Chess board” covers the entire surface of the globe and rises up. So, on the 16th floor of the building and above, it is determined in exactly the same way as at the surface. Construction Materials(brick, reinforced concrete) have almost no effect on it.

The bands of the Hartman grid are polarized and are divided into conditionally positive and conditionally negative (or, respectively, magnetic and electric). At the same time, the direction of their energy flow can be ascending and descending. At the intersections they form the so-called " Hartman nodes " about 25 cm in size (right-, left-polarized and neutral). Every 10 m, bands of greater intensity and width pass in the grid grating.

The second lattice structure is the diagonal grid curry(D-net). It is formed by parallel strips (walls) directed from the southwest to the northeast and perpendicular to this direction, i.e. from the northwest to the southeast, and crosses diagonally the rectangular Hartman grid.

Research scientists show that these grids have a negative impact on the human body. In principle, the “walls” of the grid themselves are safe. A certain danger is associated only with the nodes of the grid, i.e. with the points of intersection of the main lines. The nodal sections of the grid can adversely affect a living organism. Constant stay in the nodes of the grid leads to increased fatigue, nervousness, and the occurrence of chronic fatigue syndrome. Very sensitive people may develop more serious illnesses.

Although it is not necessary to overdramatize the situation. The knots of the Hartmann grid are dangerous only with prolonged exposure. They are not recommended to sleep and work. But, for example, many flowers grow beautifully precisely at the nodes of the Hartmann grid.

How determine where geopathogenic zones are located in the apartment? The first effective way- use a dowsing pendulum or a frame, otherwise called a “vine”. The second is to use special equipment. The proposed device helps to reveal the pattern of fields in a particular area of ​​space.

The basis of the device (Fig. 1) is a charge-sensitive amplifier with an input impedance of about 10 gigaohm (GΩ). The device is built according to a symmetrical scheme. The indicator is a microammeter with an arrow in the middle of the scale. It shows the direction of the electric field regardless of position.

The device is powered by 2 batteries of 9 V, the current consumption is approximately 0.1 mA. Third battery(9 V, current about 5 μA) is installed in the potential balancing circuit of the gates of transistors VT1 and VT2.

The signal is fed to a symmetrical antenna and then to the gates of field-effect transistors VT1 and VT2. A potential difference appears across resistors R16 and R17. An equalizing current flows through the RA2 device, the arrow deviates from the zero position and indicates the direction of the field in space. Turning the device 180° changes the polarity of the signalnal in the antenna and causes the arrow to deviate through zero in the opposite direction, i.e. the arrow again indicates the actual direction of the field in space.

Transistor VT3 stabilizes the total operating current of the amplifier.With the help of a variable resistor R6 (smoothly) and, if necessary, dividers R2 ... R5 or R7 ... R10, a zero potential difference between the gates VT1 and VT2 and the symmetry of the amplifier arms, i.e. zero readings of the RA2 instrument.

Field-effect transistors VT1, VT2 - KP303S with a cut-off voltage of about 1 V and a gate leakage current of 0.1 nA (the amount of arrow deviation depends on it). To protect against static electricity, solderingfield-effect transistors are produced only in the finished circuit. In this case, the outputs of the transistors must be shorted with wire jumpers. After soldering the transistors, the jumpers are removed.

In the manufacture of the antenna (Fig. 2), two plastic bottles with a capacity of 1.5 liters (cylindrical, without “constriction”) are taken as a basis. It is better to take transparent unpainted bottles from under mineral water. In bottles, starting from the bottom and not reaching the neck of 60 mm, holes are made with a diameter of 5 mm with minimal but intact bridges between them. Holes are burned with a soldering iron tip (through one, to give time to cool the jumper and not melt it when burning the second hole). The sting must be inserted vertically and removed quickly. A bead of extruded plastic is formed around the hole, which makes it easier to maintain the integrity of the jumpers and strengthens the mesh. The design of the device is shown in Fig.3.

Instead of high-resistance resistors R1 and R11 (about 10 GΩ), you can use ferrite cores 02.7x12 mm from the inductors of the medium wave range of radio receivers. The rod is released from the plastic screw plug by heating the core near the plug with a soldering iron. Along the edges and in the middle of the core, 7 turns of tinned copper wire d = 0.2 mm are tightly wound. The ends of the wires are tightly twisted, and the resulting bandage is impregnated with solder and rosin. As the solder cools, it shrinks, hardens, and forms firm contact with the rod. Leads are soldered to the bandages, and the rod is inserted into a 04 ... 5x15 mm PVC tube. A 03 mm hole is made in the tube for the middle lead, which can be soldered later through the hole. The tube is filled with molten paraffin for moisture resistance. Now the extreme ends of the wires are soldered together. The resistance between them and the middle terminal is just about 10 GΩ.

RA2 - pointer indicator with a symmetrical scale and zero in the middle (R, = 1000 Ohm, total deviation current - 0.05 mA). If there is no finished head, you can rebuild the indicator of the C-20 device. To do this, you need to disassemble its body, remove the magnetic system with an arrow and unsolder the coil springs. For convenience, it is necessary to turn the regulator lever and the arrow to the extreme positions. Fix the latter on the scale with a soft wedge. Now, when soldering, the spiral spring will diverge from the contact, which is required.

Remove excess solder from the contacts and tips of the spirals, set the regulator lever and the arrow to the central position and fix the arrow on the scale with a soft wedge. When the lower spring is touched by the contact, the latter must be bent. A tinned copper wire d = 0.2 mm is applied to the contact so that its end is aligned with the end of the spiral spring, and soldered to the contact. Then the end of the wire is bent until light contact with the end of the spiral spring and carefully soldered, and the second end of the wire is bitten off. Similarly modify the second spiral spring. For the convenience of soldering, a bare copper wire d = 2 mm can be wound on the soldering iron tip, the end of the wire can be sharpened and irradiated. If iron filings get into the magnetic gap of the head, it is carefully cleaned with the tip of a steel sewing needle.

Indicator PA1 (M4762-M1) helps to visually set the operating current using resistor R20. Diode VD1 prevents erroneous connection of GB2.

Resistor R18 limits the charge current of capacitor C2 through the microammeter PA1, R19 - the charge current of capacitor C1.

The power is turned on when the switch SB2 is closed. Then it is opened and the device is adjusted:

1. Turn on SB2. By adjusting the trimmer R20, the operating current is set to about 0.1 mA.

2. Press the SB3 button. By turning the screw on the body of the dial indicator with a screwdriver, set the "mechanical zero".

3. Press the SB1 button. Resistor R14 produces a balance of operating currents at equal potentials of the transistor gates.

4. Choose a suitable place in space and, comparing the readings in the straight and 180 ° inverted positions of the vertical antenna, adjust R6 to achieve zero readings. For ease of adjustment, it is preferable that the direction of movement of the handle R6 and the arrow coincide (otherwise, the extreme conclusions must be soldered to R6).

5. If adjustment is not provided, then turn off SB2 and solder the output of one of the resistors (R1 or R11) to other taps R3 ... R5 or R8 ... R10. After the final adjustment, the R6 engine should be approximately in the middle.

To identify grid elements, the adjusted device is held in space so that the antenna is vertical. Remember the position of the arrow. Then the device is smoothly moved in any direction, while maintaining the vertical position of the antenna. A decrease in the readings of the arrow to zero and again an increase, but in reverse polarity, indicates the intersection of the antenna line of the grid. The position of the antenna is fixed relative to the surrounding landmarks and the device begins to move along the strip. By tilting the antenna across the strip, new zeros are found between the positive and negative readings of the instrument arrow to the right and left of the strip. At the same time specify the direction of the strip. If the strip corresponds to the north - south or west - east line, then it belongs to the E. Hartman grid, if at an angle, then to the M. Curry grid.

When moving along the strip, the readings of the instrument arrow to the left and right of the strip may decrease to zero, and then increase again, but in reverse polarity. This corresponds to the transition of the strip through the node of intersection with the transverse strip. Remember the place of the node and continue to move on. The repeated change of polarities to the left and to the right of the strip corresponds to the transition through the second intersection node already with the second transverse strip. Further, from the nodes, it is necessary to go with the device along the transverse strips to the next nodes on them, and finally, between the nodes there will be another strip parallel to the original strip. If all stripes on the “inner side” have the same polarity, then these are the boundaries of the polar cell of one of the grids.

So, each cell with a vertical constant electric field upwards is separated from neighboring cells with the same field downwards by stripes, more precisely, by vertical planes that prevent the opposite fields of the cells from mutually neutralizing and are the boundaries for changing the direction of the fields. The fields of the two grids are superimposed and produce the resulting local sum or difference fields.

In the recently established Center for Scientific and Applied Research on Energy Information Security "Veles" (Kryvyi Rih city) they seriously took up energy information research (geopathogenic zones, anomalous zones and phenomena). The Research Laboratory of Technical Design "VEGA" has been established at the Center, which has rich experience in the development of research instruments: here is the development, production and sale of technical means and devices for diagnostics (detection) and neutralization of energy-information, fine-field radiation and geopathic zones. They are busy at the Center with popularization and training (lectures, seminars on eniology, training in dowsing and instrumental diagnostics of geopathic zones) ...

At the Veles Center for Scientific and Applied Research on Energy Information Security, the development of modern electronic devices for the study of energy information interactions of a person with the outside world is in full swing, allowing diagnosing fine-field radiation of living and inert natural objects at a new, non-traditional level. Already this year, a whole line of products of the Scientific Research Laboratory of Technical Design "VEGA" appeared in the field of studying the "aura" of living and non-living objects. This line includes such models as VEGA-2, VEGA-10, VEGA-11 and VEGA-D 01 (Thumbelina).

Unique, superior to known world analogues, is the VEGA-11 device, which can become an indispensable assistant in determining geophysical anomalies and determining geopathogenic zones both indoors and in the field. Moreover, weather conditions (rain, dampness) do not affect the operation of the device.

This device has unique properties, surpassing the Russian development of the IGA-1 type, due to the fact that it is based on new scientific approaches. Their essence lies in the fact that in a normal electromagnetic field, at the interface between two media with different conductivity, a double electric layer appears, which creates a weak electric (electromagnetic) field, i.e., if there is an object underground that contrasts with the natural (continuous) field of the Earth, then fixing these changes on the surface (intensity, polarization ellipses, frequencies, etc.) it is possible to fix this object. Using the high-frequency field illumination method, we excite this weak electromagnetic field, which makes it possible to more confidently identify anomalies in the natural electromagnetic field.

In practice, this makes it possible to detect centuries-old burials, foundations of destroyed buildings, voids in the ground (tunnels, caches, dugouts, underground passages up to 12 meters deep, etc.). The device also registers the remains of people, metal objects, metal and plastic pipelines, communication lines, and so on. Quite successfully, the device also registers the aura of a person, which the device is able to detect at distances of about five meters through brickwork up to a meter thick, which can be used to determine the presence of people inside (outside) the premises (hostages, criminals, etc.).

The device was tested and showed excellent results in terms of energy-information survey of the area near Lake Bolduk (Belarus). The work was carried out at the request of the Chairman of the ICCO, Ph.D. Romanenko Galina Grigoryevna and Vice-Chairman of the Presidium of the Moscow NGO MAIT, Doctor of Technical Sciences, Professor, Academician of the BAN Sychik V.A. during the scientific-practical conference "GIS-Naroch 2014".
