"Sniffing" Bomb Detector Stinks

How does Sniffex work? According to this website, the company touting Sniffex claims that it "detects the interference between the magnetic field of the earth, the explosive, the device itself, and the human body which allows the device to penetrate and locate even small amounts of explosives through concrete, soil, and metal barriers." Of course, there are a number of ways to detect explosives--but all have limitations--and this is the first time I've heard of "magnetic interference" being used to spot bombs. Sniffex isn't the first company to try to ride the public's fascination with wonder weapons to stock market highs, though accusations of outright fraud may make this firm unique. It is the opinion of Stocklemon that the SEC cannot be far behind this one - you don't need a bloodhound to "sniff" that something stinks at Sniffex.
