Best Free Metal Detector App That will Make your Mobile Amazing Metal Detector.

Metal Detector is an application which detects the presence of metal nearby by measuring the magnetic field value. This useful tool uses the magnetic sensor built-in your mobile device and shows magnetic field level in μT (microtesla). The magnetic field level (EMF) in nature is about 49 μT (micro tesla) or 490 mG (milli gauss); 1μT = 10mG. If any metal is near, the value of magnetic field will increase. 


Metal Detectors can be used as emf detector and emf sensor. The detector is electro magnetic field detector to detect metal and detect EMF reader. Metal detector meter in the app can also be used as EMF Meter.


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.

Disclaimer

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.
