$3,999.00

Easily find underground anomalies such as Gold Veins and Deposits, Caves and Tunnels, Water deposits, and even Buried Caches or Treasure at depths of 1 to 50 meters or more!

The Terra EZ RES PRO is a professional grade resistivity meter that is used to perform Electrical Resistivity Tomography (ERT) Surveys. ERT is used by professional geophysical surveyors to accurately locate sub-surface anomalies such as water, mineral deposits, caves or tunnels, archaeological sites, and even buried caches and treasure!

Real 2D and 3D imaging, NO GIMMICKS! With the EZ RES PRO and Voxler, you can create 2D and 3D images of what lies underground. Standard with the EZ RES PRO, Voxler is a very sophisticated and powerful Professional Geophysical Survey Graphics Program that can create images with data from the EZ RES PRO.

The EZ RES PRO comes with everything you need to perform simple and complex resistivity surveys.

A resistivity survey is conducted by placing metal probes into the ground and an electrical current is passed between them. The resistance of the current is measured in Ohms. The EZ RES basically reads a slice of what is underground depending on the resistance it encounters. To do a proper and accurate survey, the probes are moved outward at various intervals to achieve the different depth requirements considered to be half of the probe spacing. So basically, a probe spacing of 10 feet will yield an spacing of 50 feet will yield an effective depth of 25 feet and so on.

Resistivity is the opposite of conductivity. A highly electrically conductive substance will exhibit low resistivity while the opposite is true for low conductivity substances. Resistivity is the measure of resistance to electricity flow over varying distances. Higher electrically conductive substances, like metals for example, will exhibit much lower resistivity than air (as found in caves/tunnels). Factors that will DECREASE soil resistivity: (a) High moisture content (b) High soil salinity - more ions to conduct electricity; (c) Clay minerals. Factors that will INCREASE soil resistivity: (a) Low moisture content; (b) Low soil salinity; (c) Loose, non-compacted soil/gravel; (d) fractures in dry rock.

The complete resistivity scan process usually involves many individual scans, requiring numerous and repeated movements of probes---generally expanding a resistivity line outwards to achieve greater depth. Depth is generally 52% of the distance between a given set of probes. As shown in the above illustration of a two-probe array, current flows to and from the probes in all directions horizontally and vertically. As the probes are sequentially placed farther apart, the electric current goes steadily deeper. To calculate the apparent resistivity, the EZ Res Pro measures the voltage drop from the current sent from the C+ and C- wires to the current received by the P+ and P- wires. The strongest reading position is in the center of the probes.

When a significant drop in the readings (Ohms) occur, this can indicate a cave or a void is 'resisting' the flow of the current. The opposite would be true for metal. The Ohms would decrease due to less resistance to the current. Once an anomaly is located, the user can then adjust the array back and forth or flip it for a cross section to pinpoint the anomaly. The two
probe array is the simplest array to set up and the fastest/easiest to conduct. For a quick look before possibly following with more sophisticated arrays, the two probe array is the best way to start a serious resistivity study. The image on the left is of overhead and cross-section views of a typical 2 probe array that would be used to find a cave or tunnel. The same applies to finding other anomalies such as water, mineral veins, or buried caches.
