What Is Minelab GPZ 7000?

The Minelab GPZ 7000 is a high-end gold detector developed by the Australian company Minelab. It is specifically designed for detecting natural gold nuggets at extreme depths with maximum sensitivity.

Unlike conventional PI (Pulse Induction) systems, it operates using ZVT (Zero Voltage Transmission) technology, allowing it to reach depths that traditional detectors cannot achieve.

What Is ZVT (Zero Voltage Transmission) Technology?

The biggest difference of the Minelab GPZ 7000 is its exclusive ZVT technology.

Advantages of ZVT:

• Greater depth compared to standard PI systems

• High sensitivity to small gold nuggets

• Stable operation in highly mineralized soils

• Reduced ground noise and interference

Thanks to this innovation, the Minelab GPZ 7000 can detect both small, near-surface gold pieces and deeply buried large gold masses. In heavily mineralized terrains where a standard detector struggles, it delivers superior performance.

Minelab GPZ 7000 Technical Specifications

Below are the complete technical details of the device:

1. Detection Technology

• ZVT (Zero Voltage Transmission)

• Super-D coil technology

• Advanced ground balancing system

2. Coil Specifications

• 14” x 13” Super-D standard coil

• Enhanced deep search capability
