The built-in ground balance circuit can eliminate the influence of all "mineralization reactions" on the detector. The intelligent recognition mode greatly improves the depth and accuracy of effective detection. It has the characteristics of large detection depth, accurate positioning, strong resolution, and simple and convenient operation. It is mainly used to find underground metal objects (gold, silver, copper, iron, etc.), and can accurately find and identify metal objects such as scrap iron, steel bars, water pipes, and gold and silver treasures buried deep underground., Manufacturer: CFWWSAQ
