Zero Voltage ( ZVT)
Most metal detectors and gold detectors devices work according to
two technologies for searching for different kinds of metals:
1 – Very Low Frequency (VLF) technology which offer better sensitivity at higher frequencies
2 – Pulse Induction (PI) technology which offer more depth in mineralized grounds.
Each previous technologies has its own advantages, and also disadvantages and practical uses.
GPZ 7000 incorporates the unique ZVT technology, so it combines the positives of both technologies,
as a result giving high sensitivity to capture the smallest gold nuggets available in VLF technology,Transmission
with a deeper depth of up to 40% in comparison with any rival device
that works according to pulse induction technology
