I love Jeremy wades show, and honestly if he spent part of the show going in depth about his tactics he would lose viewers, most people who are watching don't fish or atleast not enough to care about that stuff...
That "newbie" has caught hundreds of different spieces of fish and many, many triple digit behemoths in multiple country's in so many different lakes and rivers.
He does have some videos on animalplanet.com where he explains why he uses the tackle and tactics he does.
He does play up the danger factor like bluebasser said, but hey, its show business and you gotta keep the viewers entertained.
