I have both a pulser (14 years) and a silver maker (closer to 20 years) and try everything I can think of when I'm on the trail of a health problem. The pulser should be in every hospital room. The silver--in creams and ointments (shampoos maybe) pretty much.
I never found silver to 'extend' the range of my pulser though, although there were times when I was drinking the stuff (and stopped when my blood pressure became high for no reason, but when I stopped the silver it started going back down) and pulsing.
I'm guessing you never tried the herbs though, to see how fast pathogens can be killed. You probably settled for silver, which as I've said, is better than nothing.
And Beck's protocol doesn't have a zapper--it's a blood purifier.
