1、High‑quality aluminum alloy material, durable and corrosion‑resistant, 2 antennas can help you accurately determine the buried position of the object and locate it. 2、The detector can identify the type of metal, allowing you to easily find metal objects that are useful to you and make detection easier. 3、The perfect combination of field archaeology and scientific theory, with high‑quality remote search system and precise positioning detection system. 4、It breaks through the conventional detection method, uses the micro‑electronic processor to control the chip unit calibration and the instrument self‑check system to make the detection more accurate. 5、It can easily and quickly scan and detect, which greatly improves the work efficiency of metal detection and reduces the labor strength of detection. Condition: 100% Brand New Item Type: Metal Detector Material: Aluminium Alloy Search System: Microcomputer CPU Control and Reflective Conductivity Search Range: Approx. 1000m/3280.8ft Detection Depth: Approx. 20m/65.6ft Power Supply: 12V 1000-1600mAh Transmission Frequency: 5.6-6KHZ Signal Frequency: 360-440H Detection Type: Gold, Silver, Copper, Gems Charging Method: The instrument has been installed with a rechargeable battery, directly connected to the charger, can be charged, charging time 10-12 hours Boot test: Turn on the switch of the host and the search instrument, the working indicator on the search instrument will flash; when the copper gear is selected on the host, the corresponding gold indicator on the search instrument will light up, and when the other silver, diamond, and gems gears on the host are selected in turn , The corresponding indicator light on the search instrument will light up. If the gear is selected on the host and the corresponding indicator on the searcher is not lit, it may be that the host and searcher have insufficient power and need to be charged. If the above conditions are normal, the instrument is normal and can be used with confidence. 1 x Transmitter 1 x Receiver 2 x Antenna 1 x Adapter 1 x Plastic Box 1 x Instruction
