Transient Electromagnetic (TEM) , GPR , Earth resistivity meter records https://sites.google.com/site/resmeter/home/records click to see 3D example 5 https://sites.google.com/site/resmeter/home/example-5 click to see example 4 https://sites.google.com/site/resmeter/home/example-4 click to see example 3 https://sites.google.com/site/resmeter/home/example-3 click to see example 2 https://sites.google.com/site/resmeter/home/example-2 This resistivity meter has been designed specially for archeology and treasure hunting. Resistivity meter is useful to locating non metal large objects in soil , as tunnels , structures ........ - Maximum Output Voltage 450 Volts, 900 V peak to peak - Output current : 1mA, 10mA, 50mA, 100mA, 250mA - Maximum Output Power 100 Watts , 200 Watts or 300 Watts - 24 Bit Analogue to Digital Conversion -Waveform Square 0.1Hz - 25Hz - remote controlled stainless steel electrodes, support from 20 to 250 electrodes , microprocessor controlled, by cable from notebook - Maximum electrode spacing from 2m to 70m -- Automatic electrode contact test - Possibility to measure IP - 12 V DC power supply. -USB PC interface Maximal detection depth to object sizes AxAxA meters is Am. As example if object is 4x4 meters the maximal depth will be 4 meter. Maximal detection depth to long tunnel high A meters is 2xA meters. As example if the tunnel is high 2 meters the maximal depth will be 4 meter. You can read: "The resistivity method is not particularly sensitive to 3-D anomalies for the same reason that it is ineffective over buried 2-D structures of finite width." and more in: chapter 8.6.7 Mapping Three-Dimensional Anomalies page 561 Applied Geophysics By William Murray Telford, W.
