This app measures magnetic field 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. When 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 your magnetic sensor (magnetometer). Note that it is affected by electronic equipment (TV, PC) due to electromagnetic waves.
* Main features:
- Alarm level
- Beep sound
- Material design
** Metal detector cannot detect gold, silver and coins made by copper. They are classified as non-ferrous that has no magnetic field.
