Made of a hybrid of cast and machined aluminum, the Ion has all the benefits of a fully machined bar-stock reel without the high price. With a large arbor for quick retrieves and a hybrid machined/cast design, this fly reel is a great choice for balancing rods of all sizes. The maintenance free Rulon disc drag delivers a no backlash, instant drag reaction from a one-way roller clutch bearing. The drag’s low start-up resistance protects lighter tippets. It has a positive position, click-drag knob with an incoming/outgoing audible click. Impact resistant matte black finish.
