This app measures magnetic field with an embedded magnetic sensor.
The magnetic field level (EMF) in nature is about 49μT(mTesla) or 490mG(milli gauss); 1μT = 10mG. When any metal(steel, iron) is near, magnetic field level 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 detector) 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, Microwave) due to electromagnetic waves.

Features

⭐ Metal detector measurement are displayed in digital format
⭐ Best Metal Detector and indicator.
⭐ Works also through walls! Detect hidden electrical wires and metals.
⭐ Make cool graphical charts of magnetic field intensity.
⭐ Vibration alarm for indication of metals
⭐ Calibrate Magnetic sensor

Note: Metal Detector apps require a magnetic sensor (magnetometer). If this app does not work properly, please check the specifications of your device.
Metal detector cannot detect gold, silver and coins made of copper. They are classified as non-ferrous metal that has no magnetic field.
