Go chasing your version of sunken treasure with Okuma’s Tesoro Casting Reels. The self-lubricating gear system uses a heat-sensitive oil-impregnated brass bushing mounted in the center of the gear. It releases oil if friction increases to keep the main gear and drive shaft running smoothly. Okuma is the first to adopt this technology, which came from large machine industry. The XL gearing design has a drag surface area that’s 50% larger than standard gear-box design. This allows the gear teeth to be substantially larger for more strength and cranking power. It essentially turns your reel into a winch for large fish. The Mechanical Stabilizing System (MSS) ties the major components – spool shaft, pinion gear, pinion gear bearing, drive shaft and main gear – together with a single support system. This enables all of these critical parts to stay in precise alignment to meet the demands of braided and wire line fishing for durability and strength under pressure. High-speed 6.2:1 gear ratio. Frame, sideplate and spool built from 6061-T6 machined aluminum. 17-4 grade stainless steel helical cut gearing. Multidisc Carbonite drag system with Cal’s drag grease. Corrosion-resistant coating process. Swept aluminum star drag for ergonomics. Anodized aluminum swept handle and ergonomic grip handle knob. Four corrosion-resistant ball bearings. Dual anti-reverse system includes a Quick-Set anti-reverse bearing and a mechanical backup. Manufacturer’s three-year limited warranty.
