Knowledge is the thing, and how to apply that knowledge. To catch a big fish, one must know where to go. With grandpa, with dad, nobody catches a big fish, but they all keep going back. In reality, that lake probably doesn't have any big fish. Others change lakes every year and don't learn one lake very well.
Timing also is very important.
Also, early spring and late fall trips are generally always most productive for the really big fish. The program also will cover how to simplify tackle for a specific trip and certain species. While it's fun to have all that tackle, there should always be those few 'go-to' baits. That's the way I approach my fishing. Bucher will end the seminar reinforcing success, which he says breeds confidence.
