Sniffex "operating principles"

I approached Lee White, Vice President for sales of HSI, and asked him how Sniffex works. This is what he said:



Things to note: Sniffex uses no battery or other power source. It runs on "the human electric field" and uses the human body as an antenna. That makes no scientific sense. The claim in the clip is that Sniffex can locate most types of explosives within "a meter or so". The videos that follow prove conclusively that it can not.
