The jack of all trades in the saltwater realm, Shimano redesigned the Spheros SW series of saltwater spinning reels to conquer both offshore and inshore waters. 
Now featuring Shimano's flagship Infinity Drive technology to improve pinion gear support and enhance the overall drive gear design, Spheros SW provides anglers with increased winding power under load when cranking against hard-fighting game fish.
Wielding both X-Protect and X-Shield for improved water resistance for increased durability in the harsh saltwater environment, Spheros SW fortifies an IPX8 water-resistant-rated body.
Key Features
Cutting Edge Technology: Made specifically for sea fishing, the model has Shimano's cutting-edge technologies used to make the model smooth, safe and extremely reinforced, among them. 
X-Ship: Supports the pinion with bearings forming a perfect fit in the gears, leaving the reel smoother and without vibrations.
X-Protect: Labyrinth system found around the body, which makes it difficult for waste to enter the interior of the model, leaving it with a longer useful life.
X-Shield: Seal found in 12 parts distributed in strategic locations preventing the entry of waste.
Propulsion: Computerized system that provides longer and more accurate casts avoiding kickbacks and wind knots.
Cross Carbon Drag: Braking with interleaved carbon discs.
