How it works
🔔 This app uses the built-in magnetic sensor (magnetometer) of your smart phone.
🔔 First of all after running this app if your phone shows high reading then immediately keep it away from every electric devices to set it normal (0μT – 49μT).
🔔 The normal Electromotive force (EMF) field level is about 49μT (micro Tesla) or 490mG (milli gauss); 1μT = 10mG. When any metal object like steel or iron is near, EMF reading will increase with a beep 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.
🚫 Metal detector app cannot detect gold, silver and copper coins because they are categorized as non-ferrous objects that has no magnetic field. But maybe you will find gold is it is together with any other metals or some treasure inside!
