There is a wide variety of geophysical techniques used around the world for information underground, some of them are: RESISTIVITY (ELECTRICAL); MAGNETIC; ELECTROMAGNETIC; GPR (ground penetrating radar); SEISMIC; GRAVITY; VIBRATION CONTROL; MARINE SURVEYS; GENERAL purpose ETC.: Geological studies, stratigraphy, study of marine beds, mechanical properties of the subsoil, location of groundwater, mining, environment, location of pipelines and facilities, geological faults, and among other search for TREASURES and archaeology.
It is the method that allows us to have a continuous flow of information from under the surface, the high accuracy of this technique provides many data quickly and at low cost.
It is a non-destructive method that produces information without digging, is used to assess the location and depth of buried objects, operates by transmitting pulses of high frequency Radiowaves to Earth through a transducer or antenna, the transmitted energy is reflected by buried objects or contacts between different layers of materials on Earth the antenna then receives the reflected waves and stores the data in the control unit.
Currently the G.P.R.(ground penetrating radar) is used in: Archaeology, environment, geology, forensic applications, localization of underground water, military applications, real estate, location of tunnels, pipelines and facilities, engineering and treasure hunting.
METAL detectors: There are basically three types according to their principle of operation; BFO (beat frequency oscillator); IB (induction balance) and; PI (pulse induction), but we will classify them according to their characteristics.
DETECTORS FOR SURFACE SEARCH:
DISK DETECTORS; Also known as plate detectors, do not offer great depth but if much sensitivity, detect objects as small as a PIN or gold nuggets even.
In discrimination mode can give an idea of the detected material provided East very superficial, are ideal for walls or tight spots, lookups also are very seldom used in the beaches.
DETECTORS FOR DEEP SEARCH:
TWO BOX DETECTORS AND DETECTORS OF PULSE; They are very powerful and little sensitivity detectors, in two cases only detect objects the size of a can up, which is an advantage to skip garbage as Crown caps, nails and wire, both work to all metal but of pulse can discriminate between ferrous and non-ferrous metals, both types of detectors are very useful in open terrain where quickly cover large areas, but because of its power are not practical if it is to operate them inside a property, especially if it is modern and is inhabited and full of furniture and installations that activated at each moment that comes close to them.
We mention these technologies to be of the more used, although there are many more, some of doubtful effectiveness and without scientific basis, but which are used widely, such as dowsing, which has its detractors but many more followers.
ground radar metal detectors The ground radar or GPR allows detection of very large objects or cavities at depths that no detector even with a frame can reach. Using a different frequency sensor can also focus on smaller targets. These devices, originally reserved for professional use in engineering, are democratized.

The Rover UC metal detector inaugurated a new generation of compact measuring apparatus and cannot be recognized as a metal detector. With the smartphone as a central unit you get the performance.
Ground radars to search for buried treasure deep It is recommended that ground radars to search for buried treasure, and detect underground cavities, such as tombs, tunnels and foundations with secret caches. Ground radar differs from classic metal detector technology and strength. Find metal detector gold to maximum 60 centimeters at ground radars.
Authentic ground radars, also referred to as GPR, allow the detection of metal targets and the cavities at inaccessible depths to other detection systems. But beware, a GPR is used not as easily as a metal detector. Indeed, there are a number of constraints to respect. Field must be completely dry, even in depth, because...Read Post

Job radar subsurface sensing device (a common terminology – GPR) is based on the classical principles of radar. Transmitting antenna device emitted ultra short electromagnetic pulses (units and fraction of a nanosecond) with 1.0-1.5 period of quasi-harmonic signal and a fairly wide range of radiation. The central frequency of the signal is determined by the type of antenna.
Select pulse is determined by sensing the necessary depth and resolution of the instrument. For the formation of probe pulses used broadband excitation of the transmitting antenna voltage drop (shock excitation method).
Emitted in the investigated medium pulse reflected off objects in it or inhomogeneous medium, the medium having excellent dielectric constant or conductivity, received by the receiving antenna, amplified wide band amplifier, converted to digital form by an analog-to-digital converter and stored for further processing. After processing the information received is displayed on the display…Read Post
Profiling provides a vertical sectional view of the subsurface environment along the path of measurement in real time. However, the role of the vertical coordinate performs during the pulse to travel from the transmitter to the boundary of the reflecting object and then to the receiving antenna. To convert this “temporary cut” in the real depth is necessary to estimate the velocity of propagation of electromagnetic waves in the environment and take into account the location of the point of reflection about the antenna device.
Propagation velocity of the probe pulse needed to assess the real depth of the objects can be found directly from the temporary cut in the presence of local or on the track linearly extended across the road subsurface object forming at radarogram characteristic hyperbolic trail. Solution corresponding asymptotes of the hyperbola depends on the speed of wave propagation in the medium. Function determining the speed of propagation of electromagnetic waves in a medium according to the diffraction image of a hyperbolic local object in the device has not been implemented and it is expected to available software systems GPR data processing on a computer…Read Post
