Shimano Biomaster is a rugged breed of saltwater fishing reels developed by Shimano. Shielded anti-rust bearings (S A-RBs) will provide the saltwater protection needed to guarantee the long-term quality of your fishing reel. The cold forged (CF) aluminium materials add further protection to these robust yet agile fishing reels.

The AR-C spool is an innovative feature on the Biomaster 4000 reel that will enable you to vastly improve your casting distance. Shimano has undertaken intensive research to create a lip design that prevents backlashes and wind knots from occurring. The special AR-C design of the spool lip minimizes friction by letting the line out the line in smaller loops.

Shimano has incorporated Aerowrap II because the pitch design perfectly complements the AR-C spool. A worn gear oscillation system ensures that energy is distributed efficiently through uniform line laying and winding shape.

One of the standout features of the Shimano Biomaster 4000 SW fishing reels has got to be X-Ship. The purpose of this feature is to provide you with extra power, smoother operation and higher power. This is achieved with a pinion gear configuration supported by double bearings. X-Ship is the distinctive feature that enables Biomaster SW reels to deliver superior performance for longer.
