I am trying to understand the technology of the Bob Beck and Hulda Clark zappers. From what I understand Hulda Clark uses pulsed DC offset and the Bob Beck uses AC. Is this right? Which is better for killing pathogens and helping the body and why?
Do zappers kill the good bacteria in the intestines?
Can I control the current output or do I need to?
Do the Hulda Clark zappers also have the benefits of the other Bob Beck devices such as the Magnetic pulser for the lymph, the coloidal silver maker, ozone or do I add these?
