Minelab GPZ 7000

The GPZ 7000 runs on Minelab's ZVT (Zero Voltage Transmission) technology, paired with a 14 x 13 inch Super-D configuration coil that includes a skidplate and is waterproof to 3 ft. One forum post summed up the appeal directly: the Minelab GPZ 7000 metal detector is proven to locate small to large size nuggets up to 40 percent deeper compared to the GPX 5000. The detector has a full-color LCD display (320 x 240 pixels), Gold Mode settings for High Yield, General, and Extra Deep ground conditions, plus Ground Type settings for Normal, Difficult, and Severe terrain. Audio runs through a 1/4 inch socket with Wi-Stream wireless signal transmission, and it ships with KOSS UR 30 headphones. Discrimination is set to All Metal mode by design, reflecting its purpose as a dedicated gold-prospecting machine rather than a general-purpose detector.
