Find ferrous metals and magnetic fields using your phone.
Metal Detector measures magnetic fields using the magnetic sensors in your phone. Normally the magnetic field strength is about 49μT or 490mG. In the vicinity of any ferromagnetic metal or wires carrying electricity the magnetic field strength is higher.
This app is useful in finding metals buried in the ground or locating electrical wires in walls among other uses. It’s great for fun say to frisk your friends or for serious DIY work.
