Dependable, versatile, and built to perform. The Nasci FD combines consistent casting and smooth retrieves with high-efficiency reeling, thanks to the INFINITYDRIVE, ANTI-TWISTFIN, and One-Piece Bail. COREPROTECT water resistance adds lasting durability without sacrificing the reel's light, responsive feel. Designed to handle a wide range of conditions, it's an ideal choice for anglers who want reliable performance without packing multiple setups.

Technology: 

• HAGANE: HAGANE is a Shimano reel design concept created to withstand continual use and extreme abuse. HAGANE is an innovation with built-in toughness and durability that works alongside Shimano's precision engineering. HAGANE is for all anglers.
• HAGANE Gare: With amazing strength and durability, the HAGANE Gear is at the very heart of most Shimano reels. Shimano, through the application of state-of-the-art technologies, gives anglers the long-lasting smoothness and pleasure that is felt when anglers first use a reel, over and over again. No cutting work is applied to the teeth of the drive gear during fabrication, instead the entire surface is calculated in minute detail by special 3D-design and then formed by Shimano's cold-forging technology. The result is assured resilience. HAGANE Gear is the fruit of Shimano's inexhaustible pursuit for durability — the strength and power of forged metal continues to represent the fundamental concept of Shimano reels.
• X-Ship Spinning: X-Ship provides improved gear durability. By supporting the pinion gear on both ends with bearings, the pinion gear maintains precise alignment with the drive gear. This allows the gears to stay in the same position under the heaviest loads. The added benefit of X-Ship technology is that friction between the spool shaft and gear are eliminated. This further benefits anglers with enhanced casting performance and casting distance of lighter lures.
• Infinity Drive: The Infinity Drive structure is an advanced structure that creates exceptionally light winding. The main shaft, which had previously been supported by the pinion gear, is now supported by a new and unique low-friction bushing that significantly decreases frictional resistance. In addition, the main shaft has undergone a proprietary surface treatment and special processing to drastically reduce rotational torque, constructing a reel that can actively wind even under heavy loads.
• SilentDrive: SilentDrive technology benefits from a total redesign of all functional parts focused on the drive gear, worm shaft and other parts. The goal: remove unnecessary noise and vibration. In doing so, the overall tolerances are improved to a micron level, ultimately creating an overall quieter and smoother reel operation.
• Anti-Twist Fin: Shimano designed the Anti-Twist Fin for enhanced line management resulting in more effective fishing. The flexible polymer fin is installed near the line roller. This maintains line tension to reduce sagging and prevents the line from falling off the bottom of the spool or wrapping around the spool in an uneven manner.
• CoreProtect: Total Protection, the concept of CoreProtect is simple: to provide water resistance without creating a heavy rotational feeling. There are three key areas of the reel that require protection: the roller clutch, the body and the line roller.
• G-Free Body: G-Free Body technology has been developed to shift the reel's center of gravity closer to the rod. By moving the center of gravity closer to the angler’s hand, the G-Free Body helps to reduce fatigue and enhance casting comfort.
• One-Piece Bail: One-Piece Bail allows the line to travel unimpeded to the line roller. The seamless design reduces friction and decreases the chance of tangles or the line catching on the bail arm.
• Cross Carbon Drag Baitcasting: The Cross Carbon Drag material provides a wider range of drag settings compared to traditional drag materials. The Cross Carbon Drag provides the smoothest Shimano drag performance ever while providing anglers with increased durability.
• Propulsion: The spool has a special spool ring shape. This creates a rectifying effect on the line and realizes both suppression of line trouble and long casting performance.
