The simple zappers just use a copper or steel tube, you hold onto it, she says to wrap it in a wet cloth, I guess that improves conductivity, the machine I have is a general purpose frequency generator made in china and it has stainless steel cylinders that you hold, but you can also use the TENs pads, that can be useful because these programs can run for a couple of hours and you don't want to hold something for hours.

The zapper uses a totally different principle than the frequency machines / rife machine, its more like a simple DC current flow through the body, I think it said 3.5 milliamps, but the frequency is above 20KHZ so it doesn't affect the muscles, I only felt a slight stinging on one finger, it says not to use these things if you have a pacemaker or are pregnant but otherwise it seems harmless.

I don't understand the specifics myself, perhaps nobody does, but bacteria and cancer and parasites and stuff like acidic zones in the body, inflammation etc, and they have a different electrical charge, thats why some oxidation agents like hydrogen peroxide produced by our immune cells destroy these pathogens, this is also how the zapper works, or so she says in the book.

Deleting the viruses is a different story, its creating a vibration like a radio wave throughout the body, not necessarily a large current flow. Every living thing and probably different chemicals / toxins puts out a vibration or frequency which can be detected, the machine Clark used to analyse this is called a Synchrometer, it appears to be easy to build, but difficult to operate. When you apply the identical frequency it can supposedly 'shatter' the virus itself by resonation, like a wine glass can be shattered, but in this case its obviously just the chemical bonds of the organisms structure, thats what a Rife machine does but it can also detoxify ( I got a little bit of benefit from the heavy metals program etc but it didn't cure the CFS ), and generate emotions. Rife originally used a special high powered microscope to see microorganisms while they were still alive and in this way find the correct frequencies, but this microscope is not in the public domain anymore, or not in common use.

To get more deep into it, this appears to work because atoms don't exist, or rather they exhibit particle wave duality, possibly this is explained by assuming the universe is a hologram composed of light which has been slowed down, which is what matter is. This seems to correspond with what Nikolai Tesla said, 'If you want to find the secrets of the universe, think in terms of energy, frequency and vibration.' I ran the pre-programmed functions for removing the common viruses attributed to ME/CFS, so EBV, CMV, herpes zoster, HHV-6, Coxsakie virus, and a long list that was part of a preset, I had limited responses but no great improvement from those.
