I agree with U on 1) that the Widesweep is much more flexible in frequency and strength with its 1 minute rest period gaps in between. Having used this driver I found I did feel some sensation around my wrists but only slight tingling, but that was all with no extra surge of energy felt elsewhere. It may be I am resistent to the input, I shall have go into this deeper as I need to get these frequencies inside of me. Do you have any suggestions on this of what I could do to improve this? I thought even though on this particular device has the yellow conductive material on the inside of the wriststraps, they could do with a little more help. I was wondering then if I should soak them in a salted water to enable me to receive the frequencies better. What do you think?. I do not think it would be harmful to zap daily, as long as you do not overdue it. I would zap on the Widesweep daily for the 78 mins. for about a week and than use this driver only 3 times per week. I would then also use the standard zap 7/20 etc. daily for as long as needed for improvement. Perhaps after that, using the standard zap only 3 times per week and so on. It all depends on how serious your health problem is and how you feel after the treatments. Personally, I have felt much more energic and lively after zapping, and oddly enough my eyesight seems clearer. I do not need to wear glasses for long distance but noticed this improvement. This could be to do with the liver being cleansed of toxins etc. I have only 3 drivers, the Widesweep, parasite and fungal. This should be enough for me at the moment but I would consider using more if I felt it was necessary. I am also buying the RG2 which is a magnetic pulser, blood electrifier, silver maker (I believe) got to check this though. It costs about $130 + P&p. from Toolsforhealing. The reason being, is that the blood electrifier is particularly good for zapping pathogens in the blood and the pulser is good for deeper applciations on the body. There lots more data on this at this site to make interesting reading. I am also thinking of applying the wrist staps to my ankles (I think you said you are doing this) and also using the two metal bars with paper towels covering them in my hands. Please answer my earlier ? about applying salted water to the wrist straps and your views. thanks........
