Daves Zappers

Zappers are electro-medicine Self Healing devices. They run on a common rectangular 9 volt smoke alarm type battery(not supplied), Alkaline last the longest(about 100 hours of continual use). They work by passing a low power approx 16-20 hz square wave signal and demonstrate the way the square wave frequency works and this is the main reason how the Zapper interacts with the body's electronic balance to get rid of All Manner of Parasites and the Diseases they create and at the same time alkalise the body.
Indeed Dr Hulda Clark Discovered That The Biggest Cause of Most Serious Conditions Are Caused By Intestinal and Liver Fluke Parasites.
These claims by Dr Clark are backed up by clinical research.
