The Zapper is an electronic device invented by Dr. Clark. It kills parasites, bacteria, viruses, molds and fungi electrically. Viruses and bacteria disappear in three minutes; tapeworm stages, flukes, roundworms in five; and mites in seven. A battery-operated, positive offset with a very low voltage from 5 to 10 volts is sufficient. It kills parasites and bacteria wherever the current reaches them. The VariZapper 2.0 comes in a padded hard-shell plastic case complete with all the accessories you need to get started (cable, wristbands, rechargeable battery module, 2 pairs of gel electrodes). The VariZapper 2.0 has 3 standard programs: regular zapping (7-20-7-20-7 min), duration zapping (60min non-stop zapping), zappicator function (groceries zapping/zappicator board needed). For other frequency programs, simply stick in a pre programmed Program Driver Card and press start. The parasite zapper, VariZapper 2.0, is built according to European medical devices standards, Class IIa. It complies with all technical requirements for medical devices for Europe, Canada and the US and is certified to that effect. It is however not a medical device in the US and Canada and cannot be recommended for any medical purposes in those countries. The unit carries a two-year warranty.
