A Thundervolt Zapper has 250,000 frequencies like a Rife machine, but it automatically scans the user while zapping and targets any pathogens it meets with its own primary matching frequency. Additionally, a secondary waveform consisting of three additional frequencies piggy-backed together is operating at the same time. Bad parasites get sandwiched and crushed between the two individual waveforms.
We also have a Body Tester that documents the amount of improvement gained in zapping. No one else in the industry has a Body Tester for retail sale. Thank you for your time.
