Technology Features of DAIWA 21 ÉMERAUDE AIR
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.
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.
TOUGH DIGIGEAR
DAIWA’s DIGIGEAR is a gear system realized through a manufacturing technique that accurately shapes the form derived from numerical analysis of power transmission efficiency by computer. Instead of casting, the gears are processed using forging, which provides higher strength, and then the gear teeth surfaces are smoothed through ultra-precision machine cutting, allowing for efficient power transmission. TOUGH DIGIGEAR enhances this by increasing the surface area of the gear teeth and the radius of the gear, further improving durability and strength, resulting in a smoother winding experience.
ATD (Automatic Drag)
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.
AIR ROTOR
AIR ROTOR is designed to achieve the ideal spherical shape for a rotating body. Through high-precision rigidity analysis, it maintains the same level of rigidity as traditional rotors while achieving significant weight reduction and lower inertia. The reduction in inertia allows anglers to stop and wind the reel at will, providing excellent responsiveness and a lighter, smoother winding experience.
LC-ABS
The LC-ABS spool features a two-step design on the front edge to enhance line release performance and streamline the flow. While maintaining the trouble-free usage of the previous ABS spool, it achieves an approximate 5% increase in casting distance combined with a reduction in spool weight.
