5, high precision and sensitivity - can accurately detect the tiny metal objects (0.1 g or even smaller).
6, battery x ray scanning machine baggage constantly testing power supply, battery failure, voltage is insufficient, when the voltage is less than did not detect the metal the red Alert light will turn on to display you need to replace the battery.   7 can produce different alarm tones according to the size of the metal in a noisy environment can be an external headset.
