Beck didn't make a zapper...

Beck didn't make a zapper, as far as I know--only a blood purifier (never did much for me but give me electrical burns on my wrists, but of course I was using the herbs and probably didn't have anything to kill) and an electromagnetic pulser (which is amazing for bacteria and virus, but doesn't do anything for parasites or fungus) so what in heck is a beck zapper?? I liked his protocol, but it didn't address parasites at all unfortunately.
