RUNABOUT

With the UNDERGROUND SURVEYOR, there is no need to transmit a signal into the earth, because of the existing signals that are already present in the earth. The SURVEYOR has very sensitive broadband receivers, enabling it to receive electromagnetic and magnetic signals. When there is an item buried in the ground, a FERF (Free Electron Radiation Field) is created enabling the receiving antennas in the UNDERGROUND SURVEYOR to identify its presence. When a hole is dug, it creates a scar on the Earth’s surface; this scar is visible to the SURVEYOR. Like any other detector ever built, it is looking for the difference, which enables the operator to locate anomalies.
The software that was created exclusively for the USA is designed to highlight items in the ground, anomalies, disturbances, etc… You can see subsurface objects in Real-Time with the GeoSurveyor 3-D Software. Also a feature that assists in detecting a target area is Auto Ground Balancing. Auto Ground Balancing defines the compensation for the varying amount of minerals in the soil by sensing the mineralization and automatically adjusting the ground balance to achieve the best performance, thus producing a more “clearly defined
target area”. One of the main items to note, is to do a large enough scan allowing you to see the background. When scanning in only one small area, determining the difference between the target and the background can be somewhat difficult. Another note to remember is to isolate suspected targets so that there is only one target per scan. This way you will be able to determine the approximate size of the object. As advancements in the software are available you may purchase upgrades, critical updates will be available free of charge. Please contact your sales representative for more information.
When using specifically designed sensors the earth’s self-potential of direct currents can be measured. The sensors become very useful when using a single forward motion just above, without contacting, the earth. With this rather simple technique, the geophysicist can trace zones of mineralization, having a strong signal, or tunnels having a weak signal. By receiving a combination of AC/DC and frequency to map potentials, we can map fields of interest. These rapid changing signals are amplified and analyzed by the software. The UNDERGROUND SURVEYOR allows for the rapid collection and interpretation of large quantities of data, making it a cost effective technique. EM equipment measures the background of the emitted signals from the earth; it then detects any differences that are present. Differences can be caused by anything in the subsurface that has disturbed the earth ( like a void, metal objects, fault, tunnels, etc…). Other available geophysical techniques that are sensitive to the presence of both ferrous and non-ferrous metal objects include metal detectors, pulse induction, resistivity, ground penetrating radar, etc…
