We’ll start this page off with a paper written by Bruce Candy, the inventor of the GPZ7000 This is in the form of a downloadable PDF file. KNOWLEDGE BASE ARTICLE Zero Voltage Transmission (ZVT) Technology Below are two methods of achieving an accurate  ground balance for the GPZ7000.
This is just released and an alternative method of ground balancing the GPZ7000. This method gives the detector a “quick start” towards the ultimate ground balance for the area being scanned. The ferrite rings will be supplied to all customers who have purchased their detector from us at no cost to them. The video will show the recommended method to be used.
