>- you don't think the shape of the wave has anything to do with
NO, I know that the wave form is absolutely critical. That is why ParaZapper has the strongest, sharpest, and truest square wave of any zapper under load.
Any zapper can produce what looks like a good squarewave when not under load but the human body or that of any animal or even a jar of water full of microbes is very complicated in its patterns of resistance and capacitance and this requires the output to be as close as possible in providing a balance to compensate for that.
>- You use multiple frequencies at once
No, we use multiple frequencies in sequence. Multiple frequencies at once can actually interfere with each other and can actually diminish the effectiveness.
While, as Dr. Clark claimed, any frequency can kill many microbes, different frequencies may be better at killing different microbes. This was established by Royal Rife and John Crane a long time back.
>- as I noted, it never worked that well for me,
A single frequency did not work that well for me either and so, that is why our first zapper was a dual frequency which surveys from our customers showed worked better than just using a single frequency.
Then we built a zapper with 8 frequencies and that one worked even better than the dual frequency one did.
Another problem that we found was inconsistency in results. We found that while one unit of a given model appeared to work great another might not produce as good of results.
At that time, we checked and found that zappers had a frequency error of between 5 percent and as much as 20 percent on some. This meant that while one zapper might produce a perfect 30,000 Hz, the next one produced could be anywhere between 24,000 Hz and 36,000 Hz for some brands. Ours were usually 5 percent accuracy which was 27,000 to 30,000 Hz with a center of 28,500 Hz.
While Dr. Clark did not think that the difference was important, I knew that it was.So we moved to 1 percent error, then to 0.25 percent and then to 0.05 percent. Royal Rife stated that the frequency used for his work had to be 0.05 percent.
At least one thing is for sure. By doing it this way, every customer is getting almost the exact same frequency or at least very very close.
So, the old 30 kHz zapper might have actually been 30,000 Hz, 27,493 Hz, 32,185 Hz or any frequency within a wide range. Many users did not know that because most sellers did not specify what the accuracy was. Actually many still do not.
With the ParaZapper 6-pack ( our current cheapest ), you get
Freq 1 30250 +/- 300 Hz for 7.5 minutes
Freq 2 29800 +/- 300 Hz for 7.5 minutes
Freq 3 30720 +/- 300 Hz for 7.5 minutes
and then it cycles back to the first frequency so that it repeats 3 times in just over one hour. And you do not need to turn it on and off and you do not have to wait 20 minutes because the changing frequency keeps microbes from adapting.
I like the old saying, "the proof is in the pudding"
If you take any single frequency 30 kHz zapper and zap the jug of pond water, it will kill many microbes but never all. There are always some that still survive. This why I challenged all other zapper sellers to try it. You could do it 7-1/2 on, 20 off, repeat 3 times, or you could do it 1 hour continuous. A single frequency does not kill all.
The 3 frequencies in the 30 kHz mode of the 6-pack will kill far more effectively than any single frequency zapper will at 30 kHz. Again, I am speaking in terms of microbes.
So how can a zapper kill worms?
By killing the bacteria that live in their gut that they absolutely require for their continued life.
BTW, this is how most of the pharmaceuticals work that are used to kill worms. Read up in some of the published scientific literature.
The problem with zappers is that many can not reach deep into the internal organs where these parasites
I have already posted about what needs to be done to achieve that.
