We are excited to announce the latest addition to the Underwater World of Trout DVD series. The latest DVD, Trout Vision And Refraction, discusses how we see trout and how they see us by examining the physiology of a trout's eyes, the refraction of light in the water, rod flash, how your movements are seen by the trout, and more. This amazing underwater DVD, in addition to Discovery and Feeding Lies will enlighten your understanding of trout and help you understand how to fish for them like never before.
