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.
