Re: ThunderVolt Zapper questions

>- Who learned that years ago, how did they learn it, and what can you tell me about this, and the results of the studies or experiments?

From 2002 to 2006, Para Systems and Devices, LLC, the predecessor to our current company, collected data from a few hundred customers in the form of a questionnaire. We compiled this data to show the relationship between several aspects of zapper usage and the relative effectiveness reported for various conditions. I have published some of that information on this forum in the past.

>- Let's just say that it worsens some conditions that my other frequency (I think 30khz) actually improves.

First, I have rarely heard of anyone's condition actually worsening.

Second, are you sure that it is 30 kHz? Many cheap zappers can be off frequency by as much as 10 percent to 20 percent. Are you sure that the 15 Hz is actually 15 Hz? Same reason.

>- I can feel the frequency of the 15hz one for some

This is normal for some. First, the human body is far more sensitive to frequencies below 300 Hz because of the recovery time of nerves.

A signal might not be felt at all at 30 kHz while a frequency at 60 Hz can be quite noticeable even if it is exactly the same voltage and current.
