Landing tough saltwater gamefish demands a reel that's geared specifically to handle not only the fish themselves but also the harsh environment in which they live. The Tiagra A series from Shimano handles these tasks with authority. Reels boast A-RB (Anti-Rust Bearings) that are specially treated stainless steel and at least 10 times more corrosion resistant than standard stainless steel ball bearings. The spools are made from cold forged aluminum then machined to provide an extremely dense, solid construction that can withstand the heavy drag pressures the reels can apply. Chrome-plated sideplate screws prevent corrosion. The two-speed gearing uses two sets of gears that are always engaged for quick, easy gear ratio changes even under load. A ratcheting drag lever eliminates the chance of the drag lever backing off due to boat vibration and allows for more precise adjustment. Twin Disk Drag System uses two drag disks and a floating drag plate to effectively double the drag surface, which provides a wide range of settings and increased durability (16 and 130 models only). The clicker increases the tension on freespool and activates a clicking alarm when a fish bites. Permalube lubrication improves freespool while maintaining protection and durability of moving parts. Metal series frames keep moving parts in precise alignment for increased efficiency and durability. Frames are machined from solid aluminum pipestock, which makes them incredibly rigid and strong for ultra tight tolerances. The Offset Ergonomic Power Grip is offset on multiple axes to allow natural hand, arm and wrist angles to improve comfort and power (TI12 and TI16 models have Ergonomic Power Handle).
