What is geoelectrical resistivity meter?

A geoelectrical resistivity meter is an electronic device used to measure the flow of electric current through the ground from probes inserted at regular intervals. Resistivity is defined as the amount of resistance to current flow, therefore the device can determine different soil compositions based on the readings. Such as if has underground water or cavity, the resisitivity vaule will be go down, the surveyor can analysis and location of groundwater.
