Les Stroud had made a two-part Bigfoot special. I found that odd because his public authority came from a practical, evidence-based approach to survival. The post also notes his earlier use of a dowser and asks why popular survival television could not borrow more from the methods of MythBusters.
That is the whole argument. A small blog post from the period when every questionable television premise apparently required a response.
