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.
