Description

The S A-RB bearings have been through the same process as our A-RB bearings; but feature shields on both sides of the bearings that reduce the possibility of salt or sand inhibiting the bearing's position. The dyna-balance feature eliminates wobble during the retrieve by counter balancing the rotor to enhance sensitivity and smoothness. By using computer balancing; an approach similar to car tire balancing; we are able to redistribute the rotor weight to create smooth rotation and eliminate vibrations. Building upon the successes of Fluidrive; Fluidrive II features a large master gear polished using a wrapping process; increasing the efficiency of the retrieve. The most obvious component of the propulsion line management system is the new propulsion spool lip design. Through tens of thousands of casting tests and computer simulations it has been determined that this new spool lip design provides longer casting distances than a standard spool lip design while preventing backlashes and wind knots from forming. Super stopper II anti-reverse uses a one-way roller bearing that eliminates back-play. This provides the angler with instant hook setting power. Normal oscillation systems use a constant rotation of the oscillation gear that; when translated to the cam; provides an inconsistent spool speed. This results in the line lay that stacks at either end of the spool. By using an oval oscillation gear; we are able to alter the speed of the oscillation cam to provide a consistent spool speed. This results in an even line lay that provides excellent castability and manageability. From an angling perspective; every individual who has owned and enjoyed using Shimano tackle has a reason to thank a Japanese visionary named Shozaburo Shimano; who in 1921 declared “I aim to make Shimano's products the best in Kansai; then the best in Japan; and finally the best in the world. For over 80 years; Shimano has concentrated on precision engineering; one step at a time. Creating the most innovative products and processes you can hold in your hand today.

  • It’s a Shimano
I paired it up with my Bubba Tidal and man can this reel cast far. It’s perfectly smooth and works like you except from a Shimano. The free spool bait runner is perfect for using live bait. This is my second bait runner and I love it.

  • Great reel for surf fishing
I bought the 4000 model for surf fishing in the Florida panhandle. Caught many bull reds, pampano, lady fish, all with no problems. The bait runner feature works great when rod is placed in a PVC rod holder driven in the sand. I paired the reel with a Tsunami Trophy rod, model TSTSS-702H. For surf fishing, this combo seems to work really well and looks great. For line I use Power Pro Super 8 Slick Fishing Line, 30lb test. I tried other line that was not as smooth and it was super noisy at the guide when reeling. Super 8 slick solved that problem. All in all, a great reel that is my go-to for surf fishing. ... show more

  • Excellent I bought three!!!
the baitrunner drag on these is great for trolling when you want to be able to set the pole down. The fish comes and hits the bait and doesn't feel you or your boat in a way that makes him spit the bait. The baitrunner drag goes to work letting out line and making a clicking noise so you can tell you are getting a bite. You then just pick up the pole and turn the handle and whamo the regular heavy drag kicks in and you hook the fish. When you are trolling the baitrunner drag is a much lighter drag that is just strong enough to be able to pull your shiner through the water without letting out line. The Daiwa version of this type of baitruner drag sucks by the way. It does not make enough noise to hear well when it is letting out line from a bite and it can't be set light enough for a bass to not feel the pole before you switch over to the regular drag. So it defeats the whole point of having it. The Baitrunner drag must be light enough to conceal your presence to the fish until you are ready to set the hook. If not then the fish just spits your bait out if its a bass which will spit the bait out as soon as they feel you or your poll pulling back for any length of time. ... show more

Since I got it on Amazon warehouse deals it was a steal. Great reel. Smoother than Penn Battle 2 and Fierce 2 series. Shimano baitrunner is Super to penn live liner and okuma Avenger versions. My only knock is the 4000 size uses felt washers and not carbon fiber ones.
