Technology Features of DAIWA 2020 TATULA SV TW
TWS (T-Wing System)
Traditional level wind systems were designed, as their name suggests, to lay the line evenly across the spool. However, during casting, they often created resistance, leading manufacturers to experiment with different internal diameters and shapes to enhance line release. But these efforts had their limits. Excessive enlargement of the level wind compromised its original function, restricting advancements to minimal adjustments, such as refining the internal diameter. Some solutions included increasing the distance between the spool and the level wind or narrowing the spool width to prevent the line from hitting the level wind at sharp angles. While partially effective, these methods were essentially temporary fixes that led to side effects such as elongating the reel body, reducing palming comfort, or decreasing line capacity.
DAIWA's TWS (T-Wing System) addresses these contradictions not with compromise but with innovation, achieving both precise line winding and an expanded resistance-free range during line release. By significantly widening the resistance-free zone where the line makes contact with the level wind, particularly right after it leaves the spool, TWS has dramatically enhanced the long-casting performance of DAIWA baitcasting reels. Simultaneously, the smooth line flow facilitated by TWS has proven effective in preventing backlashes.

ZERO SHAFT
Typically, spools are supported by a shaft integrated with the spool itself, but with ZERO SHAFT, the spool is supported solely by ball bearings. By eliminating the shaft, unnecessary resistance is removed, resulting in optimal spool rotation. This feature prioritizes casting performance, making it a crucial element of the stress free casting. Previously known as the Speed Shaft, this spool mechanism was renamed "ZERO SHAFT" in 2021.
SV (Super Versatile) concept
The SV concept maximizes the effectiveness of magnetic brakes to deliver practical advantages in a field. It significantly reduces the risk of backlash, making casting easier and more effortless. With minimal adjustment of the magnetic dial, the SV concept allows for a wide range of lure weights—from lightweight rigs around 4 to 5 grams to heavier lures—to be handled smoothly and without stress.
UTD (Ultimate Tournament Drag)
By re-evaluating the washers and grease from the ground up, DAIWA has refined the drag system to reduce initial resistance when a fish is hooked, ensuring the line starts to slip smoothly and consistently. This advanced drag system, which surpasses the previously established standards set by DAIWA, is designated as "UTD" (Ultimate Tournament Drag).
AIR BRAKE SYSTEM
The AIR BRAKE SYSTEM significantly enhances casting accuracy while minimizing the risk of backlash, providing a stress-free experience. During full casts, the brake engages effectively, but in low-speed operations like pitching, the inductor rotor remains retracted, reducing the braking force. This system allows for low-trajectory casting and seamlessly balances pitching and casting at a high level.
