An italian Company Has Design 100% Scientific Equipment Called 3D Locator For Detection And Exploration Of Groundwater Sites. 3D Locators Had Introduced For You The World's Most Advanced Geophysical Systems Working on Geomagnetic and Geo-frequency Sensing System, 3D Locators Systems Have The Ability To Locate The Target And Calculate The Depth And Analyze The Permiabile Factor Of The Target, 3D Locators Are 3 in 1 Systems Are Equipped With The Latest Long Range Positioning System &Geomagnetic Sensing System & Geo-frequency Sensing System For More Accurate Field Data Recordings And To Target The Highest Accuracy In The Groundwater Industry. Our Products Long Range Positioning System - For Accurate Location Of The Target. Geo-Frequency Sensing System For Analyzing The Depth And Permiability Of The Targeted Zone. And Geomagnetic Sensing System For Locating Targets In Small Areas Where Long Range Surveys Aren't Possible. Permeability Is The Property Of Rocks That Is An Indication Of The Ability For Fluids (gas or liquid) To Flow Through Rocks. High Permeability Will Allow Fluids To Move Rapidly Through Rocks. Permeability Is Affected By The Pressure In a Rock. This 3D Locator Is The Worlds First System Which Finds The Permeability.
