Metal Detector

Metal Detector -sometimes like Dangerous Contraband machine to avoid Like knife ，Knives and guns

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.

UseFul

This can be used to find metal. objects such as nails, wires and any other metallic object. this metal detector cannot detect gold, copper and silver because they are non-ferrous and they don't have magnetic field.

If you are using metal detector and the app gives the high reading then you just need to re calibrate the magnetic field detector sensor. This is done by opening the metal finder app in your phone and shaking your phone gently for 4 to 5 times to re-calibrate the metal detector app. now you can easily use the metal detector app and can detect metal around. this metal detector is the best metal scanner for scanning of ferrous materials such as metal detector - body scanner, please rate the app if it helped you!
