Gpr

V Georadar - GPR (Ground Penetrating Radar) This ground penetrating radar (GPR) has been designed specially for treasure hunting. The GPR can find subsurface heterogeneities, such a cavities, tunnels and other objects. All GPR are excellent to survey in rocks and sands, good in rather dry soils without clay, and useless in soil with clay and wet soils. For treasure hunting all GPR are useful to survey in rocks, and usually useless in soils, because of most soils have high conductivity. The obtained information immediately appears on the laptop display. The GPR can find good, subsurface cavities larges than 1metre x 1m x 1m, with an almost flat ceiling. Smaller objects will be found with difficulty and not so deeply. The laptop can be any, with Windows XP or Vista, and USB port , 1.4GHz or more. The GPR can to be carried by a single operator. In the sounding process, the operator is getting real-time information as a radiolocation profile (radar gram) on a display (on a notebook). The GPR draw the radar gram for 60 seconds (in this time operator can see the received part of the radar gram), after that operator can record it on a hard disc with any name for further use, or/and start new. The GPR can scanning with the time window (time that gpr receive after transmit pulse) 50nS, 100nS or 200nS.Wen the operator carry the GPR, antennas must be from 5 to 20 centimetres over the ground surface. Distance between antennas can be from 0.5 to 1.5 meter The antenna system is dipole, unshielded, air coupled. Antennas 75MHz - length-1,5m, depth-10m 100MHz - length-1m, depth-8m 150MHz - length-0,75m, depth-6m 250MHz - length-0,5m, depth-4m 350MHz - length-0,3m, depth-3m Current consumed - 0.4A from 12V battery Weight - kg 4 with battery Depth - detection depth - Distance between ceiling of a cave in rock(limestone) and ground surface . If a ceiling is flat or oval and cavity is large. Depth is dependent on the parameters of the rock or soil With the GPR you will be able to detect cavities in rock or sands with dimensions width Xm, length Xm, height Xm at a depths 2*Xm. As an example if a cave have width 2m, length 2m, height 2m and flat or oval ceiling, the GPR will can detect the cavities on depth 4m in rock. The GPR can detect cavities in rather dry soil without clay with dimensions width Xm, length Xm, height Xm on depth Xm. As an example if the cave have width 2m, length 2m, height 2m and flat or oval ceiling, GPR will be able to detect the cave on depth 2m in soil. If the ceiling is not flat or oval, or is acute, the depth is smaller. When the soil is wet, the depth is smaller. In practice it is very difficult or impossible to predict how deep GPR can see in soil because it is depend from soils characteristics. In the "WORLD ATLAS OF GROUND CONDUCTIVITIES" you can to see if your region is suitable for GPR survey, if a GPR will have good depth. If ground conductivity is less than 1mS/m the conditions are perfect. If ground conductivity is more than 10mS/m , GPR will be useless in this region , you can to use a GPR only on rocks in this region. CONTACT: Mr.Ranga Babu, Mobile: +91-9676369999.

OKM Gepard GPR Ground Penetrating Radar with Android Tablet PC The Gepard GPR is a very flexible, transportable and powerful ground penetrating radar for detecting underground items like pipelines, cavities, cables, conduits, tunnels, bunkers, foundations and the like.The Gepard ground penetrating radar uses an unidirectional unshielded transmission system to reach maximum depths up to 40 meters deep. This light, agile and compact unit can be easily operated by a single operator. The RADAR (Radio Detection and Ranging) sends a signal into the ground and awaits the reflection or echo of the signal to detect sub-surface anomalies, like the following: underground walls, basements and concrete reinforcements hidden cavities, graves and sepulchres water level and underground rivers and aquifers buried pipelines, conduits and cable harnesses backfilled wells, galleries, trenches and dugouts septic tanks, distribution boxes and drainage pipes secret tunnels, bunkers and shelters buried treasure chests, statues and caches The Gepard ground penetrating radar is using a multiple transmission frequency range starting at 60 MHz up to 300 MHz which is realized by adjustable telescopic antennas. It furthermore supports many automatic adjustments to optimize your ground surveys on specific soil types, which makes the handling of the Gepard ground radar very easy. You just set your depth resolution and start surveying. The measured data of the ground penetrating radar is directly transferred to an Android Tablet PC. The Android software receives the data via Bluetooth and displays it immediately on screen. The software has the capability of integrating a GPS signal, Google Maps, automatic filtering and entering notes for later recollection of specific scan details. Additionally, automatic filtering capabilities are useful to improve the results of your scan and find hidden objects and structures more easily. Due to the integrated GPS all scan positions can be stored along with the scan data.

GPR is: A geophysical- approach that is, precise, fast and high-resolution for subsurface investigation. Non-invasive, non-destructive and completely safe procedure. One and only possible non-intrusive method capable of accurately locating non-metallic subsurface features and utilities (example- clay, concrete, fiberglass, PVC conduits or fiber-optic cables). A geophysical survey technique based on transmitting pulsed electromagnetic (EM) energy into the subsurface and ascertaining the strength of the reflected energy. Effective in case enough contrast in material properties (dielectric permittivity) between a buried target and its surroundings exists. Applied by Epitome in order to detect and map buried pipes, cables, structural reinforcement, voids, disturbed ground, material degradation, subsurface layers and buried objects. Gained by use of transmitting and receiving antennae which can be mounted on a cart, skid plate or vehicle, or can be hand-held. A technique that allows skilled and experienced personnel to attain distinct survey data and geophysical expertise to process and interpret the results.

EpitomeGS is a Ground Penetrating Radar Survey company in India. Our Services are GPR, SUE, Underground Utility, Underground Scanning & Mapping survey in India. Ground Penetrating Radar operates by transmitting high-frequency radio waves pulses down into the ground through an antenna. Ground Penetrating Radar is distinctly able at not only mapping buried structures but also relatively measuring their depth, and supplying an all-important thorough detail. The antenna is moved over the surface to be inspected. The transmitter redirects a diverging beam of energy which is reflected in various underground objects or different contacts between different earth materials. The radargram measured on the vertical scale is in units of the two-way travel time, that’s the time taken by the EM wave to travel down to a reflector and back to the surface. The travel time then is transformed into depth by relating it to on-site measurements or assumptions about the velocity of radar waves in the subsurface material under investigation. Radar wave speeds vary between 60–175 mm/ns for most geological materials. more info:https://epitomegs.com/
