Metal Detector uses the device magnetic sensor to measure the strength of magnetic field and turn the device into a metal detector. Metal Detector let you find surrounding magnetic field, electronic waves or metal(steel and iron) . Once there is a metal nearby, the reading value will increase. It can be use as a body scanner, emf meter, wires finder, pipe finder or even ghost finder scanner.
Metal Detector(EMF Meter) can display the magnetic field in µT(micro tesla), mG (milli Gauss) or G (Gauss). 1 µT = 10 mG; 1000 mG = 1 G; The magnetic field in nature is about (30µT ~ 60µT) or (0.3G ~ 0.6G) which means if there is a metal presence nearby, the value of the reading should be higher than 60µT or 0.6G.
Cautions
- Not all device has magnetic sensor. Please check it in your phone specification. If your device does not have one, no metal detector(emf meter) application can work on your device.
- The accuracy of metal detector(emf meter) entirely dependent on the device magnetic sensor (magnetometer).
- Electronic waves like laptop, television, microphone or radio signals can effect the accuracy of magnetic sensor. So avoid such places and keep away when using this app.
- This app cannot work on detecting non-ferrous metal such as gold, silver and aluminum etc. as they has no magnetic field.
Most ghost hunter use Metal Detectors(EMF meter) for ghost detection as they claim that ghosts have an influence on magnetic fields. I am not sure about that but please let me know if it’s true.
