Expert Sense Simulation [ESS]

When a rod bends, it naturally generates restoring force—energy that attempts to return it to its original shape. This “strain energy” is one of the most critical factors shaping rod performance. DAIWA’s independently developed ESS system analyzes and designs this strain energy, allowing engineers to clearly identify strengths and deficiencies numerically. More importantly, it enables the integration of anglers’ sensory feedback into the design process, resulting in rods that more closely match what anglers truly seek.

AGS – Air Guide System

AGS employs carbon-fiber guide frames that offer approximately three times the rigidity of titanium. This prevents micro-signals transmitted through the line from being absorbed by the frame, allowing them to be delivered directly to the blank with exceptional sensitivity. The lightweight carbon structure also contributes to overall weight reduction—particularly in the tip section—further enhancing sensitivity.

SVF COMPILE-X

By reducing resin content and increasing carbon fiber density in the carbon sheets that define rod performance, this material achieves lighter weight, higher power, and a slimmer profile. The strong repulsive force of the blank results in sharp casting performance and outstanding sensitivity that clearly communicates lure action.

X45

Through extensive research, DAIWA concluded that preventing blank twist requires reinforcing the conventional 0°/90° carbon structure with a ±45° bias cross. X45 minimizes twisting during casting, lure work, hooking, and fighting fish, leading to dramatic improvements in power, control, and sensitivity.

X45 Full Shield (X45 Cobra Shield)

This advanced structure applies ±45° carbon bias reinforcement from the outermost layer of the blank—a zone where twisting occurs most frequently. This dramatically increases anti-twist rigidity and unlocks higher casting accuracy and the rod’s full inherent performance.
Applicable only to: 722MRB-SV AGS25

3DX

3DX is a support structure focused on enhancing shape recovery. A honeycomb carbon pattern with excellent stability and restoring force is applied around the rod’s outer circumference. Because a rod naturally becomes slightly oval when bent, stronger restoring force allows it to return to a perfect circle more quickly, improving tip recovery, flight stability, and casting distance.

V-JOINTα

Created using high-strength Nano Alloy material and DAIWA’s precision processing, V-JOINTα evolves the original V-JOINT by providing greater strength, lighter weight, and a smoother bending curve. Slimming the joint section improves swing-through and handling in cast-intensive techniques.
Used only on: 832MSB-SV AGS21, 722MRB-SV AGS25

V-JOINT

A bias-structured carbon sheet is used in the joint section to create a distortion-free bending curve similar to that of a one-piece rod. Compared to rods without this structure, it significantly improves power, stiffness, and recovery speed, producing a more ideal action.

TUBULAR POWER SLIM

This slim, long tubular blank uses thick-walled, high-density HVF graphite to deliver powerful resilience and smooth flex. It offers excellent casting performance along with a controlled, enjoyable level of flex and strength.

CWS – Carbon Wrapping System

DAIWA’s proprietary method for securing guides and reel seats to the blank uses carbon cloth instead of thread. This carbon-wrapped structure reduces weight, increases holding strength and anti-twist rigidity at the attachment points, and improves durability against cracking. Its unique carbon-woven appearance also adds a strong visual presence.

Additional Notes – Product Design Features

Murakami-Inspired Blank & Grip Design

Since the 20th anniversary models, Heartland AGS rods feature a red-based design. The blank uses a color tone that shifts depending on how light hits it, while the grip incorporates subtle color differences separated by accent rings.

Medallion

The Heartland series medallion—a symbol of authenticity—is included.
