Specification: Item Type: Metal Detector Material: ABS Size: Approx. 26 x 9cm / 10.2 x 3.5in Search System: Microcomputer CPU Control and Reflective Conductivity Voltage: 100-240V Search Range: Approx. 1200m / 3937ft Detection Depth: Approx. 25m / 82ft Transmission Frequency: 5.6-6KHz Signal Frequency: 360-440Hz Detector Battery: Rechargeable NiMH Battery, AAA, 1000mAh Detection Type: Copper, Gold, Silver, Gems Gross Weight: Approx. 828g / 29.2oz Working Condition: 1. On a full charge, open the main detector, extend the antennae, turn on the sensing switch, press the corresponding button for the item to be detected, adjust the depth and range search function of the main detector for detection; 2. When detecting the specified item in a stable handheld position without any other interference, the detector will swing from side to side; the swinging amplitude will increase when detecting larger items; Power On Test: Turn on the main unit and search device, the working indicator light on the search device will flash; when selecting the gold gear on the main unit, the corresponding gold indicator light on the search device will illuminate. Successively selecting other gears such as silver, gem on the main unit, the corresponding indicator lights on the search device will illuminate. If the gear on the main unit is selected but the corresponding indicator light on the search device does not illuminate, the main unit and search device may need to be recharged. If the above situations are normal, it means that the device is normal and can be used with confidence.. Package List: 1 x Metal Detector1 x Plug Cord 1 x Instruction Manual Note: 1. It is important to operate carefully in undisturbed wild forest environments and maintain stability.2. The host and transmitter must be turned on together to enable detection.3. Manual measurement, please allow some errors.
