To me the guys who are considered "Pros" are the one's that make a substantial percentage of their income from Crappie fishing. They do this either by providing an active and successful guiding service or/and follow a major tournament trail (CrappieMasters, Crappie USA, Magnolia CC, ect.) and having enough success to place in the money consistently. Most of the "Pros" I know can go to any given lake and catch fish immediately to within a few hours of being on the water....they can almost smell a crappie, LOL. Crappie fishing rises to another level when there is money on the line. I would refer to someone like you said who drops structure and or learns other structure on their lakes, learns the creek channels and bends in them that hold fish, where the flats are located and where the bait fish are at all times of the year as a "serious" or "dedicated" Crappie fisherman....or maybe even a "Crappie Fanatic". BTW, I like to think of myself as a "Crappie Fisherman", LOL!!!
