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 49?T(micro tesla) or 490mG(milli gauss); 1?T = 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 app, and they had experimented as a ghost detector.
The accuracy depends entirely on the magnetic sensor (magnetometer) in your device. Note that it is affected by electronic equipment (TV, PC, etc.) due to electromagnetic waves.
When the app does not work properly, it means that your phone’s sensors are damaged, broken or non-existent. To initialize the sensors, point your phone up towards the sky and move it in a figure 8 pattern.
Metal detector cannot detect gold, silver and coins made by copper. They are classified as non-ferrous that has no magnetic field.
