It detects the presence of metal nearby by measuring the magnetic field value. This useful instrument uses the magnetic sensor built-in your mobile device and shows magnetic field level in μT (microtesla). The Best Metal Detector allows to identify metal object in close area, because all metals generate magnetic field which strength can be measured with this tool.
Usage is quite simple: launch this application on your mobile device and move it around. You will see that the magnetic field level shown on screen is constantly fluctuating. Colorful lines represent the three dimensions and the numbers on top shows the value of magnetic field level (EMF). The chart will increase and the device will vibrate and makes sounds announcing that metal is close. In settings you can change the sensitivity of vibration and sound effects.
