I saw an unboxing video on YouTube a few years back, by a Scandinavian bloke who had bought a cheap Gold Bug Pro from China, knowing it would be a fake. Every detail of the packaging, paperwork, detector, coils, etc, was indistinguishable from a real one! I don't know what you'd find on the inside if you took one apart, but without verification of legitimacy from Fisher or a trusted local agent, I think you'd be buying a pig in a poke.
