Product Features

In mobile phone detection mode, the device works by sensing signals from the middle shell of mobile phones, so it delivers high recognition performance and triggers alarms for non-ferrous (non-magnetic) metals such as gold, silver, copper, aluminum and tin.
It will not alarm for common ferrous (magnetic) metals including iron, steel and magnets. Ferrous metals far heavier than a standard mobile phone cannot be filtered out and will also trigger an alarm. For metals in composite materials, the detection result is uncertain and depends on the distribution and strength of their magnetic properties.
Metal detection mode: The detector boasts high sensitivity and can easily identify metal objects as small as a paper clip.
Equipped with a leather holster for easy portability.
Green power-on ambient indicator light; flashing green light indicates normal operation under power-saving mode.
Two alarm modes are available for manual flexible selection: sound-light alarm and vibration-light alarm.
Low battery warning function with red indicator light reminder.
Built-in high-capacity rechargeable lithium battery supports 10 hours of continuous operation.
Built-in charging function with 4–6 hours charging time: red light stays on during charging, and green light illuminates once fully charged.
