Compared to the ATF-DX, the ATF-EX reduces the weight of the riser’s upper and lower limb pockets. This enhances torsional stiffness around the sight window, minimizing unwanted movement and provides optimal balance for stable precise shooting.
The newly developed T-BLOCK structure enables precise left and right adjustments during bow alignment. It replaces the current lateral locking bolts with a 5mm wrench-tightened system, enhancing overall stability. To make sure precise and strong lateral locking, a rail-type mechanism made of special steel is incorporated inside the T-BLOCK allowing an additional lock from the rear of the riser. The new system allows simple and precise center adjustments without the need to remove the string, whilst ensuring a secure and strong locking mechanism.
The new tiller bolt design is made of strong stainless-steel material capable of withstanding heavy shock from shooting. It features gradient lines for precise and accurate adjustments during tiller setting, and the rear-mounted bolt ensures a strong and secure lock.
The riser is designed to allow upper and lower weight dampers to be mounted on the rear of the limb pocket. This enables control of vibrations generated by shooting. The riser weight balance can also be freely adjusted to suit the individual archer's shooting style and preferences.
The overall design of the ATF-EX is inspired by the flowing curves and solid structure of sports cars. The harmony of lines and surfaces create a dynamic yet refined silhouette, achieving an aesthetic balance between accuracy and sense of speed.
WIAWIS continues to use the Mathews’ EHS (Enhanced Harmonic Stabilizer) damper system, which effectively absorbs the vibrations occurring at the moment of shooting. This provides a stable and smooth shooting feeling all the way to the fingertips.
