Technology Features of DAIWA 2026 CERTATE SW 20000H
MONOCOQUE BODY
The MONOCOQUE BODY in DAIWA reels refers to a single-piece body structure. Traditional spinning reels covered the drive gear with a body and body cover, secured by several screws, which posed strength issues. The MONOCOQUE BODY eliminates the body cover, directly setting a high-precision plate into the body. This change supports the body with the entire plate surface instead of just screw points, significantly enhancing precision, rigidity, and sealing. Also, because the fixed part of the screw that occupied space inside the body has been removed, It allows for larger drive gears, providing more powerful retrieves and smoother fights with big fish.
POWERDRIVE DESIGN
The PowerDrive Design is the next-generation engineering concept for large spinning reels, developed to ensure high reliability when battling big fish around the world. This design consists of two key technological units: the PowerDrive Engine, which provides efficient and powerful winding performance, and the PowerDrive Rotor, which features a rational spherical structure that achieves both high rigidity and low inertia.
ROLLER POWER OSCILLATION
The Roller Power Oscillation system addresses the issue of friction resistance in the oscillation mechanism, which can lead to power transmission loss during prolonged, high-load fights with large fish. To minimize friction to the absolute limit, the conventional pillar-based sliding mechanism has been replaced with a two-ball bearing oscillation system. This innovation enhances oscillation efficiency by approximately 30%, ensuring smoother initial responsiveness even under heavy loads, while providing a lighter yet more powerful winding experience.
POWERDRIVE ROTOR
The PowerDrive Rotor is the front unit designed to achieve both high rigidity and low inertia through a rational spherical structure. It is composed of two advanced technologies: Crank Power Bail and Tough Line Roller System.
With its uniquely sculpted rotor shape, appearing as if it were carved from a solid sphere, the PowerDrive Rotor maintains perfect symmetry and high balance around the rotational axis. This design ensures exceptional rigidity, allowing it to withstand unexpected external forces with ease.
Additionally, the bail and line roller integrated into this rotor have been completely redesigned, enabling precise line guidance and a seamless transition into smooth retrieval operations.
In big-game fishing, the ability to instantly retrieve the released line in any situation is of utmost importance. The Crank Power Bail addresses this need with an optimally inclined, crank-shaped bail design and an enhanced spring mechanism, ensuring that tensioned lines are securely guided into the line roller while preventing accidental bail openings. Additionally, the thick-walled, hollow-pipe structure provides exceptional rigidity, making it highly durable even under extreme conditions.
CRANK POWER BAIL
In big-game fishing, the ability to instantly retrieve the released line in any situation is of utmost importance. The Crank Power Bail addresses this need with an optimally inclined, crank-shaped bail design and an enhanced spring mechanism, ensuring that tensioned lines are securely guided into the line roller while preventing accidental bail openings. Additionally, the thick-walled, hollow-pipe structure provides exceptional rigidity, making it highly durable even under extreme conditions.
OVERSIZED POWER DIGIGEAR
The Oversized Power DigiGear takes the highly durable G1 Duralumin MC Tough DigiGear, already known for its exceptional strength, and enhances it further by increasing its diameter by approximately 10% and its thickness by about 6%. This advancement elevates the gear to an unprecedented level of robustness, minimizing flex even under prolonged high-load fights and ensuring a consistently stable gear mesh. By significantly reducing power transmission loss, it guarantees a smooth and effortless winding experience.
POWERDRIVE ENGINE
The PowerDrive Engine is a body unit designed to deliver high-efficiency and powerful winding performance. This PowerDrive Engine is composed of two key technologies: Oversized Power DigiGear and Roller Power Oscillation. By leveraging DAIWA’s proprietary Monocoque Body, it has been possible to further enlarge the drive gear, maximizing its capabilities. Additionally, the oscillation mechanism has been completely redesigned, ensuring a noticeably lighter and more powerful winding experience from the first turn of the handle.
TOUGH LINE ROLLER SYSTEM
Designed to withstand repetitive high loads, the Tough Line Roller System features an enlarged support surface and an integrated roller shaft with the bail arm, eliminating the looseness that previously occurred at the joint. This enhancement significantly improves durability.
Additionally, the newly designed Braid-dedicated line roller minimizes friction resistance with the line, ensuring a lighter and smoother retrieval experience. This innovative system delivers exceptional rigidity, durability, and trouble-free performance, making it a highly reliable feature for demanding fishing conditions.
ATD TOUGH
DAIWA’'s ATD (Automatic Drag) technology is an innovative system designed to address the issues found in traditional drag systems. Previously, the main problem was the lack of smoothness when the drag first engaged. ATD ensures a smooth initial drag, releasing lines with consistent tension under strong pressure, and offering gradual resistance under lighter pressure. This adaptability reduces the need for frequent adjustments of drag force and also improves hooking rates. Enhanced drag washers maintain drag strength during long fights, giving anglers an advantage against large fish. ATD provides a stress-free and efficient fishing experience.
ATD TOUGH utilizes carbon washers to achieve superior durability. By optimizing smoothness and responsiveness, it allows anglers to focus on the fight without worrying about drag settings.
MAGSEALED
DAIWA's MAGSEALED technology is designed to prevent water, salt, and debris from entering the reel, using magnetic fluid to form a barrier that protects critical components like bearings, line rollers, and gears from saltwater. DAIWA adapted magnetic fluid technology initially developed by NASA for dust protection in hard drives used in space. Unlike traditional rubber seals that increase handle rotation friction, the magnetic fluid is held in place by a magnetic field, reducing friction and enabling smooth operation. This technology enhances the reel's durability and performance, significantly improving reliability in harsh fishing environments without requiring meticulous maintenance.
MAGSEALED LINE ROLLER
The line roller directly encounters water and sand carried by the line, making its waterproofing crucial for maintaining initial performance such as rotational feel and sensitivity. The MAGSEALED LINE ROLLER significantly reduces the ingress of salt and foreign particles. Additionally, improved rotation enhances the effectiveness of reducing line twist.
LC-ABS SW
Building upon the LC-ABS system, which optimizes the spool ring shape for smoother line release, the LC-ABS SW introduces a two-stage tapered design on the upper side of the spool's line-winding area, directing it toward the spool ring.
This innovative shape reduces frictional resistance between the line and the spool, resulting in a smoother, more efficient line release and enhanced performance in the latter half of the cast.
The benefits are particularly noticeable when using thicker lines, where cast diameter changes significantly. In such cases, casting distance is improved by approximately 2%, providing a measurable advantage for long-range fishing.
