Fly Fishing Reel
Fly fishing reels are intended for use with fly rods. These reels have a deep spool to accommodate backing and fly line. The reel is really just a line catch because when you fly fish you usually use hand power to pull the line out and in. If the fish nibbling is bigger, it will want to pull out the line you have out and then empty more line from the reel. It is only then that you fight the fish with both rod and reel.
There is everything from cheap fly fishing reels in graphite but also more expensive and finer in aluminum. It is simply a question of quality and what you have to demand. The reels are also classified into different classes. For example, if you have a rod in #5/6, you would like to match it with a reel in class #5/6.
