Dyer's physical limitations have not dampened his determination and positive spirit. He started fishing at age 5 and began tournament fishing at age 15. He refuses to use special equipment, wanting to cast with one hand as others do with two. He casts by tucking the rod under his jaw and whipping it around with a quick left-to-right twist. He reels fish in while holding the end of the rod under his chin. He ties knots with his tongue and unhooks fish with his teeth.
