Fly fishermen use artificial flies as a lure. Most flies have almost no weight and by themselves could not be cast with other types of rods and reels. The fly rod works because it uses a much heavier line than the other types. It is the line that is being cast. The fly simply goes where the line goes. Fly casting looks more difficult than it is. In less than a couple of hours most beginners can learn the basic cast. Fly casting is more involved than other types of casting. There are fly fishing schools that teach fly casting.
