So, after turning on your mobile device then move your gadget around your room or the place where you lost your costly thing. Best metal detector for Android is contain a Progress Bar and it will show you the frequency or radiations as you go near to the metal or any gold thing which is lost from you.metal detector show you the frequency of metal. From metal detector scanner you can easily guess that which frequency is matched with your relative metal like gold silver or any other metals.
metal detector measures magnetic field with an embedded magnetic sensor.
The magnetic field level (EMF) in nature is about 49μT(micro tesla) or 490mG(milli gauss); 1μT = 10mG. When any metal(steel, iron) is near, magnetic field level will increase.
Launch metal detector on your mobile device and move it around where it shows magnetic field or any electronic device near by. You will see that the magnetic field level shown on screen is constantly fluctuating.
Not every model of smartphone has a magnetic field sensor. If your device does not have one, the application will not work. Sorry for this inconvenience.
The accuracy depends entirely on your magnetic sensor (magnetometer). Note that it is affected by electronic equipment (TV, PC, Microwave) due to electromagnetic waves.
