The plate is made from a block of "A7075 Super Duralumin" material that is lightweight yet strong and requires high precision. The skirt part matches the reel by matching the outer diameter of Shimano/Daiwa counts. The biggest feature is that you can change the handle pitch in 4 increments of approximately 0.07 to 3.0 inches (70 to 75 mm) increments, making it possible to achieve more aggressive fishing.
