Introducing the Minelab GPZ 7000 Gold Metal Detector. No manufacturer until now has even attempted or been able to perfect a new revolutionary technology available ONLY in the new GPZ 7000 gold detector. Amazing features that take gold hunting to a much higher level to (now) detect really deep gold nuggets easier than ever, even the smallest pieces of gold you missed before. The dream of all gold hunters is to have technology available to discover deeper gold in so-called worked out gold areas. The Minelab GPZ 7000 metal detector has been tested and proven to locate small to large size nuggets up to 40 % DEEPER than the deep seeking GPX 5000!
