Saracione's salmon and steelhead models feature a multi-disc drag system with a 10 position drag knob located on the back side plate of the reel. Additionally, each Disc Drag reel model features a preset Gear & Pawl drag system also; designed to control spool overrun when lighter disc drag settings are made. This is not just a "clicker” it is a spool controlling drag system. All salmon and steelhead disc drag models can be easily converted for LHW or RHW reeling. Spare spools are available and can be quickly changed. All Mark IV reels are designed for freshwater use only. They are very "Sport specific in design” and are designed specifically for salmon and steelhead fly fishing with long two handed rods.
