The 2017 Theory series of spinning reels that start from size 2004 to 4000, is designed with the objective of achieving the lightest possible weight allowable, whilst maintaining smooth rotary performance, a reliable drag system and longevity.

The Theory comes packed with Daiwa’s latest technological advancements and features that translates into a fishing reel that surpasses it design objectives whilst exuding a quality only achievable from precision engineering.

Incorporating Daiwa’s state-of-the-art reel technology, each 2017 Theory comprises the following features:

Magseal - a magnetic seal formed from the use of a membrane of magnetic lubrication and magnets to create a saltwater barrier to reduce water penetration into the shaft housing of the reel. Being magnetized this lubrication system reduces any friction, minimise dust intrusion whilst eliminates oil spray and improving the life expectancy of the reel.

Infinite Anti Reverse - A specially designed anti reverse bearing that prevents back winding and minimises any such play when onto a fish.

ATD (Automatic Tournament Drag) - A redesigned spool support that increases the support of the spool across the entire length of the main shaft that helps to dissipate drag washer pressure more efficiently to reduce pulsing of the drag when fighting fish.

Engine Plate - A backing plate on either side of the reel housing that strengthens and reinforces the rigidity of the reel cranking mechanism.

Zaion - A high density carbon composite material that is uses for reel body and rotor construction, that has the same strength as magnesium, is 20% stronger than Nylon/ABS material and is 50% lighter than Aluminium.

Air Bail - A one piece construction hollow tubular stainless steel bail arm for maximum rigidity and strength with minimum weight. With no protrusions, slack line from a cast, falls effortlessly, down the bail onto the line roller as the rotor is turned, without snagging or hanging up.

Digigear II - A perfectly milled gearing system, whose gear teeth design and finish, enable extraordinary smooth running, with the least resistance with a long life span.  

Air Rotor - A redesigned rotor system that is 15% lighter in weight with a lower centre of gravity to improve the dissipation of line pressure on the rotor.

ABS II - An anti-backlash system that comprises a re-designed feature of the spool that allows line to peel away in larger loops when casting to prevent backlash, which translates to improved casting distance.

Rotor Brake - A braking system that keeps the rotor stationary when the bail is open.
