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. Item Type: Underground Metal Detector Material: Aluminum Alloy Maximum 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 conductivity Search Range: Approx. 1000m / 3280.8ft Detection Depth: Approx. 15m / 49.2ft Battery: 1 x 12V 1000mAh rechargeable battery (built in) Signal Frequency: 400 to 470MHz Detection Type: Gold, silver, copper, stone, etc. 1 x Underground Metal Detector 1 x Power Adapter 1 x User Manual
