We have improved on the design with added features like longer battery life, and a low battery warning. These changes by no means alter the effectiveness of the unit. Our unit design has been certified and approved by Dr. Clark's son, Geoff. Feel free to compare our design with the original circuit as shown in the book. Click HERE for a look at our schematic.
Casing is high-impact ABS plastic.
Weight is only a few ounces - very lightweight. Case is black in color. This device is for researchers only. Before using consult your professional health practitioner or Medical Doctor. The Zapper has a full 3 Year Parts and Labor Warranty on all internally mounted components.
