WHAT IS ZVT TECHNOLOGY?

Zero Voltage Transmission (ZVT) technology creates ultra-constant high-power opposite polarity magnetic fields. ZVT provides users with superior ground balance to enhance detector stability in mineralised soils and will detect gold nuggets at extreme depths that exceed all current competitor products.

WHAT IS THE PERFORMANCE OF THE GPZ 7000? HOW DOES IT COMPARE TO OTHER MINELAB GOLD DETECTORS?

The GPZ 7000 is our best performer on the medium to larger nuggets, even in highly mineralised or variable ground. It retains superior depth capabilities compared to any other detector while still providing good sensitivity to smaller, shallower targets.

WHAT COILS CAN I USE ON MY GPZ 7000?

The GPZ 7000 detector has Minelab branded, and aftermarket coils available for purchase. Minelab branded coils are available from Minelab certified dealerships. You can purchase the 14” or 19” Super-D coils. NuggetFinder coil have released 2 Minelab approved aftermarket coils. A 12” round Super-D coil and a 17” elliptical Super-D coil which can be purchased by NuggetFinder stockists.

CAN THE GPZ 7000 DISCRIMINATE CERTAIN METAL TYPES?

No, the GPZ 7000 does not have any discrimination capability.

WHAT IS THE DIFFERENCE IN PERFORMANCE OF THE DETECTOR BETWEEN THE NORMAL, DIFFICULT AND SEVERE GROUND TYPES?

The Difficult Ground Type setting is the default setting and is recommended as gold is usually found in areas with highly mineralised soils. The Normal Ground Type setting will provide the greatest detection depth but can only be used in “quiet” soils where there are lower levels of mineralisation in the soil.
If the detector is running unstable or noisy when using a “Normal” ground type you should switch to “Difficult”.
The Severe Ground Type will provide the lowest detection depth and should only be used when detecting in areas with extremely high levels of mineralisation. This setting should only be used in areas where you need to raise the coil above the ground when using the “Difficult” Ground Type setting.

WHY DO I NEED TO USE THE YELLOW FERRITE RING WHEN GROUND BALANCING?

When ground balancing, the yellow ferrite ring artificially adds additional data to help the GPZ 7000 improve the ground balance accuracy. This should always be used to ensure smooth operation. Sweep the coil over the yellow ferrite ring in a figure 8 motion ground balancing, ensuring that you sweep over the yellow ferrite ring with each figure 8 movement. When balanced correctly you should hear a smooth audio tone when sweeping the coil over the yellow ferrite ring.

WHY DOES THE MANUAL RECOMMEND A SWINGING ACTION, OR FIGURE-8 MOVEMENT FOR GROUND BALANCING?

When ground balancing the GPZ 7000 a swinging or figure-8 movement is recommended as the GPZ 7000 constantly monitors the changes in the soil. Sweeping the coil over as much ground as possible ensuring that you sweep over the yellow ferrite ring with each swing/figure-8 motion when ground balancing allows the detector to gain as much information as possible about the local ground conditions which provides a superior ground balance.

I HEAR AN OCCASIONAL DROPOUT WHEN USING THE WM12 WIRELESS MODULE. WHY DOES THIS HAPPEN?

Wireless audio is susceptible to audio dropouts when the signal is blocked. Audio dropouts can be reduced by ensuring a direct line of sight between the WM12 and the detector. It is best to wear the WM12 as close as possible to the detector. This minimises the path to the wireless transmitter and makes it less likely that the operator's body will block the signal path between the WM12 and the detector.

WHAT IS THE BATTERY RUN/CHARGE TIME?

The GPZ 7000 will operate for approximately 8 hours when commencing with a fully charged battery. Charging the battery will typically take 5 – 6 hours. The WM12 wireless module will operate for approximately 12 hours on a fully charged battery and takes around 12 hours to charge when charging via the BC10 charger.

IS IT SAFE TO CHARGE BATTERY FROM 24V TRUCK BATTERY?

No, the GPZ 7000 battery should only be charged from a nominal 12V car battery system when charging from a vehicle. You will need to run the charger through a DC to DC converter if your vehicle has a 24 volt system.

WILL AN ALKALINE BATTERY PACK BE AVAILABLE FOR THE GPZ 7000?

No, Minelab currently has no plans to release a replaceable cell or alkaline battery pack.

WHAT ARE THE USB CABLES IN THE CARTON USED FOR?

There are 2 USB cables supplied in the box with your GPZ 7000. The USB-A to Mini-USB cable is used for charging the WM12 wireless module. The USB-A to USB-B is plugged into the rear of the screen pod and is used for software updates.

CAN THE SOFTWARE IN THE GPZ 7000 BE UPGRADED?

On the rear of the screen pod is a USB-B port that can be used if a software upgrade is released. Check the downloads section of the GPZ 7000 page on our website for updates.
