I bought this because I moved to a trout area and was used to fishing ponds/lakes previously.
The video quality is good, but was filmed in the mid 1980s. The DVD walks you through the different types of water and how they should be fished. It also shows the different types of acquatic insects, their stages, and which flies match the hatch. The host is a biologist and credible--the video shows him actually take fish as well.
Although a tad dated, the principles in the DVD were good--helped me understand how to fish running water.
