Feature:1. [Extensive Detection Range] Featuring remote search system and precise location detection system, this metal detector can detect up to 1000m range and 15m underground depth, ensuring thorough and accurate metal detection.2. [Adjustable Frequency] With a signal frequency of 400 to 470MHz, this metal detector can identify specific types of metals such as gold, silver, copper, and stones, thanks to its frequency adjuster.3. [Long Lasting Battery] Built in 1000mAh rechargeable battery, this metal scanner offers a long battery life, allowing for extended use during outdoor exploration.4. [Aluminum Alloy Construction] Made from aluminum alloy material, this metal finder ensures longevity and robustness, withstanding the demands of various conditions.5. [Convenient and Efficient] This metal detector enables convenient and quick scanning and testing, enhancing the efficiency and reducing the labor strength of testing tasks.Specification:Item Type: Underground Metal DetectorMaterial: Aluminum AlloyMaximum Detection Depth: Approx. 15m / 49.2ft(This instrument can detect at least 6m for a 5x5cm object. For a 30x30cm object, it can detect 5 to 8m, and if an object of this size is buried for a long time, it can achieve 15m. If the area of the object is larger, its detection depth will be deepened.)Specific Functions:1. Metal detector can accurately determine the buried location of the object and can be located.2. Metal detector can also rely on frequency regulators to identify specific types of metals.Search System: Microcomputer processor control and reflection conductivitySearch Range: Approx. 1000m / 3280.8ftDetection Depth: Approx. 15m / 49.2ftBattery: 1 x 12V 1000mAh rechargeable battery (built in)Plug: AC100-240VSignal Frequency: 400 to 470MHzDetection Type: Gold, silver, copper, stone, etc..Package List:1 x Underground Metal Detector1 x Power Adapter1 x User Manual
