Overall Weight: Approx. 260g (excluding batteries)

Ingress Protection Rating: IP53

Multiple Power Supply Options: Powered by common batteries; 2 AA batteries for easy replacement.

Ultra‑long Working Hours: Approx. 200 hours of continuous normal operation and 30‑day standby time, energy‑saving and eco‑friendly. It supports charging and low‑battery alert.

Advanced Programming Function: Operators can determine the metal content of detected objects via sound‑light alerts.

Power‑saving Function: The device features automatic wake‑up and auto power‑off.

Operation & Controls: One‑key power on/off; sensitivity adjustable from Level 0 to 30 (low to ultra‑high), with quick switching between levels.

It supports earphone connection and adjustable alarm modes to adapt to different environments.

Multiple Detection Modes: Ferrous metal, non‑ferrous metal and all‑metal detection modes.

Users may select a mode for detection according to actual conditions with no parameter setup required.

Sensitivity Range: Covers one detection grade.

Detection Capability: ≥300mm

Continuous Working Stability: ≥200h

Alarm Sound: ≥80dB(A). The alarm tone shall be distinguishable from other prompt sounds; volume increases with the size of detected objects.

Alarm Reset Function: The detector can automatically reset alarm status. Alerts stop immediately when the detector moves a specified distance away from the detected object.

Extreme Operating Environment: Continuous operation for 4 hours at -40~+70±2℃.

Mutual Interference Resistance: Multiple detectors can operate normally simultaneously with a spacing of 0.2m between units.

Resistance to Ambient Metal Interference: Moving metal objects beyond 0.2m shall not trigger false alarms. For detectors near large metal objects, detection performance shall automatically recover within 1 minute after moving away from such objects.

Environmental Adaptability: Usable under complex ambient conditions.

Material: Shock‑resistant and impact‑resistant PC+ABS plastic.

Radiated Magnetic Flux Density: The magnetic flux density of the radiated magnetic field emitted by the detector shall not exceed 10μT at any point on its surface.

Detection Sensitivity: Tested in accordance with test objects and corresponding detection distances specified in Table 1 of GB 12899‑2018, with zero missed alarms.

Test Object T1: 5.5cm; Test Object T2: 6.0cm; Test Object T3: 9.5cm; Compliant with Grade A standard.

Charging Port: Standard Type‑C port for charging.
