Description
Metal Detector is in the 3rd set of the Smart Tools collection (EMF detector, ghost detector).** Metal Detector apps require a magnetic sensor (magnetometer). If this app does not work, please check your specifications.This app measures magnetic field value using a magnetic sensor that is built into your device.The magnetic field level (EMF) in nature is about 49μT(micro tesla) or 490mG(milli gauss); 1μT = 10mG. If any metal is near, the value of magnetic field will increase.Usage is simple: Open the app, and move it around. The magnetic field level will constantly fluctuate. That's it! You can find electrical wires in the walls (like a stud finder) and iron pipes in the ground.A lot of ghost hunters had downloaded this...
