The Thundervolt's Frequency Freeze mode of operation can and will match the resonant frequency of a parasite exactly. There are no fourier transform approximations involved. I have witnessed this with my instrumentation when zapping customers.
The proof of the parasitic destruction is verified by the rise in the pre-zap and post-zap Body Tester numbers.
Some of my customers get a welcome boost in their body vitality in as little as 15 minutes.
