Thiels study shows that multiple frequency is better
>- She said it doesn't kill things in the deep bowls, right up front,
Yep, and that is why she was upset with me. I proved her statement wrong.
Her zapper was just not powerful enough and she did not bother to use the 4 point contact, 3 points positive.
>- Does that sound like she cared about precise frequencies?
No, that is just how poorly the original zapper was designed. Go back and review Dr. Thiel's study. It illustrates quite clearly that the zapper did not work for every one with the same condition. There was something missing.
The engineered model that he used helped to improve the results because it had more than one frequency. The data from the study clearly showed that the engineered model worked better than the original zapper.
The Thiel study shows definitively that the engineered multiple frequency zappers work much better than the original zapper.
