Approved Zapper

Dr. Hulda Clark has chosen not to patent or license the Zapper technology that she developed in conjunction with her son, Geoff Clark. This has encouraged many private companies to produce and market their own version of the "Zapper". Dr. Clark is not directly involved with any company that makes and/or sells Zappers.

Until recently, Geoff Clark would test any commercial "Zapper" and lend his approval to, thereby certifying, only those devices which meet Dr. Hulda Clark's criteria for a Zapper. Essence Instrument's Multi-Zap  Zapper was approved by Geoff Clark in 1999.

Please note: The Zapper "certification" service was no longer being offered by Geoff Clark when this most recent version of the Multi-Zap was introduced in 2002. Although the letter below refers to an earlier version of the Multi-Zap, the 'new' Multi-Zap is an improved version and it retains all of the features and specifications of the original.
