Powerful detection accuracy eliminates interference from everyday items such as mechanical watches,

 keys, belt buckles, coins, lighters, cigarettes, and large metal objects, accurately detecting mobile phones and triggering an alarm.

High sensitivity: Detects mobile phones of different brands, in different orientations, and placed anywhere on the body.

Strong anti-interference capability: Two devices can work side-by-side without interference.

 It can function normally even with large metal objects nearby (such as X-ray machines).

Ability to perform omnidirectional metal detection, detecting metal objects from multiple directions and triggering an alarm. 

The highest detection sensitivity can detect metal objects as small as a one-yuan coin, achieving horizontal and vertical detection,

 solving the problem of older security doors that would alarm horizontally but not vertically when detecting small metal objects.
