Hi, I forgot to mention, if you are shopping for a zapper, you want to make CERTAIN in the case of schizophrenia that is based on a root cause of pathogens or parasites, that it has the ability to work in a "plate zapping" set up. In other words, you want to make certain you can use microscopic slide samples of the brain and nerve sheaths, etc. to direct the majority of the frequency or frequencies or electrical pulses to that tissue, brain tissue, nerve tissue, spinal cord, etc. etc. This is FAR more effective than general "zapping" and frequency therapy. Again, without testing, be it Dr. Clark's synchrometer, Fscan, Dr. Sutherland's photoanalysis, Dr. Loyd's radionics saliva test, etc. etc. how will you know what to "shoot" for? I know from my experience that "general zapping" will NOT treat the more serious conditions alone, nor it is effective against them alone... this is precisely why Dr. Clark, Dr. Sutherland, and other's recommend FREQUENCY SPECIFIC "zapping" or frequency therapy to target specific pathogens and parasites, and the "plate zapping" also. Plate zapping is more effective than general zapping, so if you are "shopping" for a zapper, make certain it can be used in plate zapping, particularly for a brain and nerve disorder, so that you can focus the electrical energy or frequency toward those tissue areas or tissue SPECIFICALLY and FREQUENCY specific to the pathogen (s) or parasite (s) involved.
