1、Detection Scope: With a detection range of 800 meters and underground detection depth of 14 meters, with remote search and precise position detection system, it can identify specific types of metal through frequency regulator. 2、Aluminium Alloy: The underground metal detector is made of excellent aluminum alloy, corrosion resistance and oxidation resistance, with a long service life, can be used in various harsh environments. 3、Applicable Range: The transmission frequency is 5.6‑6KHz, and the signal frequency is 360‑440MHz, it can be used to detect metals such as gold, silver, and copper, with stable performance and high efficiency. 4、High Performance: Microelectronic processor control chip unit calibration and instrument self test system to ensure accurate and rapid detection, with high sensitivity and stability, can identify the type of metal. 5、Battery Powered: The underground metal finder is powered by a 12V lithium battery, with a large capacity of 1000mAh to ensure long term and continuous use, making it convenient to use anytime, anywhere. Item Type: Underground Metal Detector Search System: Microcomputer Processor Control And Reflection Conductivity Search Range: Approx. 800m / 2624.7ft Detection Depth: Approx. 14m / 45.9ft Battery: 1 x 12V 1000mAh Rechargeable Lithium Battery (built in battery) Transmission Frequency: 5.6-6KHz Signal Frequency: 360-440MHz Detection Type: Gold, Silver, Copper, Gems, etc. Functions: Accurately determine where objects are buried. The frequency regulator can be used to identify the specific type of metal. For a 5x5cm object, it can detect at least 6 meters. For a 30x30cm object, it can detect 5-8 meters, and if an object of that size is buried for a long time, it can reach 14 meters. The larger the area of the object, the greater the detection depth. 1 x Metal Detector 1 x Power Adapter 1 x User Manual
