How it works
• This app uses the built-in magnetic field sensor of your smart phone.
• First of all after running this app if your phone shows high reading then immediately keep it away from everything to set it normal (0μT – 59μT).
• The normal Electromotive force (EMF) field level is about 59μT (micro Tesla) or 590mG (milli gauss); 1μT = 10mG. When any metal object like steel or iron is near, EMF reading will increase with a beef sound.


Precautions
• Not all phones are equipped in such a sensor. Please check it in your phone specification. If your device does not have one, the application will not work.
• The accuracy depends entirely on your smart phone magnetic sensor (magnetometer).
• Radio waves like computer, laptop, TV and Radio signals can effect magnetic sensor. So avoid such places and keep away when you run this app.
• This app will not work non-ferrous metal like gold, silver and aluminum etc. as they has no magnetic field. This app cannot be used as gold detector.
