Metal Detector app uses your devices magnetic sensor to measure magnetic field values and turns any Android into a real metal detector .
Data is displayed in PT ( micro Testla ) .
1 T = 10mG ( milli Gauss ) . The magnetic field in nature ranges from 25 to 65 ut ( 0.25 to 0.65 G ) .
Any higher measurement is an indication of metal in the area .
When there is metal in the area , magnetic field increases .
App works best detecting ferromagnetic materials , such as iron and can't detect non - ferromagnetic materials such as aluminum .
App works best detecting metals up to 15cm away.

Metal Detector app is simple to use , just open it and move it around .
If the magnetic field values rise there is metal in the area .
Accuracy of the app is entirely dependent on the magnetic sensor in your device and is affected by electrical equipment such as TVs , PCs ... due to electromagnetic waves .
If the app does not work as it should then the problem be in your magnetic sensor .
Maybe your device does not have one .
Or try to initialize the sensors by pointing your phone up and rotate it in a figure 8 pattern .
Remove magnetic covers from your device for accurate readings .
Magnetic covers will influence the magnetic sensor in your Android device .
If your device's case contains metal elements remove the case before using the app .
Ghost hunters also use Metal Detectors for ghost detection as they claim that ghosts have an influence on magnetic fields .
