GPZ 7000 ground Balance

Recommended Posts


Hello all,

I don't like to execute line 4 every time the GPZ 7000 needs to be ground balanced, is this necessary? I have not been doing it. Bad or good?

Ground Balance with the Ferrite

  1. Find an open area free from targets and place the ferrite on the soil surface.
  2. Turn GPZ 7000 ON.
  3. Select Quick Start on the Detect page.
  4. Select Reset Audio and Detection Settings.
  5. Carry out Noise Cancel.
  6. When ground balancing, press and hold the Quick‑Trak trigger, then start to sweep the coil at normal detecting height in a figure 8 motion.
    IMPORTANT: Make sure that you pass the coil over the ferrite almost immediately when you start the ground balancing procedure.
  7. Continue to sweep the coil over as much ground as possible, for 10–12 seconds, while passing the coil over the ferrite every sweep, as shown. NOTE: Once the audio tone remains quiet and constant when the coil is swept over the ferrite, ground balance is complete.
  8. Release the Quick-Trak trigger button and start detecting.
