Tools: Metal Detector

Did you know that your mobile phone has a built-in magnetic sensor or EMF sensor for measuring the magnetic field value?
Best free metal detector app to create amazing metal detector or stud finder for your mobile. Now find metal objects like rings, bracelets and treasures with your phone. When it detects metal around you, the device beeps loudly.

Metal Detector App Features and Uses
√ detects metal object signals at a range up to 30 cm.
√ A value less than or equal to 0 means no metal is present.
√ Detect hidden wires and iron pipes in walls.
√ This can also be used as a find key tool.
√ Works well for ferromagnetic materials such as iron, steel, nickel and cobalt, etc.
√ An immediate beep sounds when a metal object or electromagnetic signal is detected.
√ Best metal detector app with results in analog and digital format.
√ Real-time graph of reading makes it more cool and interesting.
√ If your phone does not have an electromagnetic sensor, this app will notify you.
√ Some ghost hunters claim that this metal detector app can also be used to detect ghosts, spirits or paranormal activity.

How it Works
🔔 This app uses a magnetic sensor (magnetic machine) built into your smartphone.
🔔 First of all, if you see high readings on your phone after launching this app, immediately move away from all electrical devices and set them to normal (0μT-49μT).
🔔 A normal electromotive force (EMF) field level is about 49 μT (micro tesla) or 490 mG (milligauss). 1 μT = 10 mG. If a metal object such as steel or iron is nearby, the EMF reading increases with an audible beep.


caution
🚫 Not all phones are equipped with these sensors. Check your phone specifications. The application will not work if it is not on your device.
🚫 Accuracy depends entirely on your smartphone magnetic sensor (magnetism).
🚫 Radio waves such as computer, laptop, TV and radio signals can affect magnetic sensors. So avoid these places and stay away when running this app.
🚫 Metal detector app cannot detect gold, silver and copper coins because gold, silver and copper coins are classified as non-ferrous objects with no magnetic field. But perhaps you will find that gold goes with other metals or treasures!
