By polishing the gear surface to maximize tooth contact, the Fluidrive II feature of this reel makes for a smooth cast. For the retrieve, the Dyna-Balance feature of the Symetre 2500 FJ, a counter balancing of the rotor, eliminates wobble. On the durability side of things, the cold forged aluminum spool of this reel has a design geared toward lasting strength. These features are all shared throughout the Symetre line of spinning reels. The 2500 FJ differs from the other Symetre models in terms of inches of line retrieve per crank, weight, pounds of maximum drag, and line capacity.
