In any event, to get back to the task at hand, how do these devices
differ and do you need to use all three of them? In short, they are
different in major ways and, Yes, you do need to use them all to be more
effective in eliminating parasites of all types. The Zapper kills by
passing an electrical current through the body. Electricity travels on
the surface of muscle tissue and will not penetrate the body like radio
waves or x-rays do. Therefore, there are large areas of the body that
the current cannot reach, making it ineffective in eliminating parasites
in those locations. Areas such as the contents of your stomach and your
intestines, your sinus cavities, parasites inside gallstones in your
gallbladder and/or liver, and the blood stream and lymph tend to be
impervious to the Zapper. Unfortunately, large numbers of parasites live
in all of those areas. So you need different devices to reach different
areas.
