Do you have any sources or more explanations about this subject please ?

What about the electrocution of small organisms ? What do you think about this story :

NOT SO LONG AGO, AN AUSTRALIAN FARMER, AFTER ZAPPING HIMSELF ACCIDENTALLY AGAINST AN ELECTRIC FENCE, noticed that the Ross-River Virus he had been infected with for several months had disappeared. After being told about that strange occurrence, one of his farmer friends –a sufferer as well-, intrigued, repeated the experiment and got well as a result (The West, 06/06/96).

I have had better results by using a zapper with a high output voltage (15V, 24V, 36V, 45V). What do you think is the most important parameter ? Output voltage ? Output frequency ? Waveform ?

I have done some measures of the amount of current traveling in the human body with the same output voltage and different frequencies, and i can state that the frequency does not influence the amount of current flowing in the body. The only thing the frequency does is that it change the perception of the current :
->With low frequencies, it is painfull to endure more than 1mA .
->With higher frequencies, it is easier to endure up to 8mA.
->More than 8mA and it becomes painfull again but not with the same sensations.

Note that most zappers have a so low voltage that the current flowing in the body even with wet electrodes is smaller than 1mA. That's why most zappers don't kill parasitic worms in my opinion, the bigger the organism the more resistant they are ?
The other problem with zappers is that the current will always travel the path of less resistance, hence many areas of the body are not influenced by the current.

>- They kill primarily through the introduction of metal ions. Copper is known as a strong anti-bacterial, for example. Silver is as well.

Not even reasonably true or correct for most zapper users. Even when the electrodes such as stainless steel, or even better, titanium, bacteria, protozoa, ets are killed. Titanium is not easily soluble and does not have much of a toxic effect under electromotive force. Additionally, it is easy to show that the ringing caused by the sharp leading and trailing edges of a square wave can cause the death of many microbes. Filtering the signal to produce a slower rise and fall time will reduce effectiveness but will not significantly change either the total power applied or the number of ions produced.

It is also easy to show that voltages as low as 1.5 volts at micro-ampere current can kill bacteria over time and this is not enough to create any significant metal ions. The introduction of positive DC square waves improves and speeds the result.

Additionally, There is a way of reducing the free metal ions while increasing the voltage of the square wave, doubling the effectiveness.

>- This is why lower frequencies are said to be more effective in a zapper. Lower frequencies are turned "on" waveform-wise much longer, giving more time for the positive ions to be released.

Another complete misunderstanding. Regardles of the mode or the frequency, that zapper as well as most zappers, outputs a 50 percent duty cycle. This means that out of each minute that the zapper is on, the positive voltage and current flows for 30 seconds.

>- you will temporarily feel well from a zapper usage, but then will steadily worsen. You will be in actuality, feeding your unwelcome visitors

You, obviously have not read " parasite Zapping and the Zapper" as it explains how to avoid the copper ions, almost completely.

>- Another danger is that copper itself can be poisonous. Those with diseases like Wilson's disease should not use a copper electrodes. Use graphite electrodes instead

Bunk! Graphite is a poor conductor compared to most metals. It is less conductive than NiChrome which is designed for higher resistance.

Conductivity

Silver 6.30×10^7
Copper 5.96×10^7
Titanium 2.38×10^6
Stainless 1.45×10^6
Graphite 2 * x 10^5

This means that copper is 300 times as conductive as graphite. Therefore, graphite is close to 1/300th as effective in producing results.

>- Zappers may also kill organisms through other more minor ways, such as hydrolysis, induced magnetic fields, and the creation of heat.

While they can have effects through these mechanisms, it is highly unlikely to occur with significance in normal usage. All of these things would occur in a very localized area and as a result, have a very limited effect overall, even locally.

>- But overall, frequency is not an important factor in the zapper effect.

How extensively have you studied zappers and their effects? Your statements do not very well agree with my thousands of hours and dollars spent as well. While there is a general effect caused by the rising and falling edges of a waveform, there is also a specific resonance that can produce better results for any specific microbe. The very reason that we are producing zappers with more accurate frequencies is that we find that the closer to an exact frequency that you get, the better the ressults. If he were alive, I would recommend spending some time with R.R.Rife. but there are many others who can provide a lot of education in this respect.

to use specific pathogen frequencies you need a frequency generator, then you can either use DNA pathogen frequencies:

or Newport frequencies that he created by dowsing:

Frqs can be delivered in more ways than just via DC electricity. Actually the more dehydrated your body is from modern Chemical warfare the worse the result of a contact device.

The zapper argument is that one frq with enough harmonics can cover nearly all pathogens. Now there is truth to that but as Hulda found out later nothing is every 100% effective. Even a lay person can tap a 9v battery and get benefit from it, a zapper especially those with more power like the Ultimate Zapper showed real results for me.

But by refining the frq and using a more powerful delivery system like an F165 one can go further. So to answer your question, there are programmable Frequency Generators like the F165 that can be used to drive a Plasma tube a Bean or used as a contact device.
