Features & Benefits
The side that hits the ball is soft, while the inside is hard; two types of resin.
The “Ai-DUAL TRI-BEAM Putter,” like the previously released Ai-DUAL Putter, is equipped with the Ai-DUAL insert, which was perfected after approximately 15,000 simulations and the creation of 72 different prototypes. Unlike the Ai-ONE insert and Ai-ONE Titanium insert, the Ai-DUAL insert is made entirely of resin, employing a structure with a soft resin on the side that hits the ball and a hard resin on the inside.
This insert not only provides consistent ball speed but also generates more forward spin.
The Ai-DUAL insert features a complex, winding shape at the boundary between the two resin layers, similar to the underside of the Ai-ONE insert. This design, developed by AI, focuses not only on the stable ball speed regardless of where the ball is struck, as seen in the Ai-ONE insert, but also on the spin imparted to the ball. Generally, due to the gear effect, a ball struck on the upper part of the face tends to have forward spin, while a strike on the lower part tends to have backspin. Naturally, this also affects the distance the ball rolls. The Ai-DUAL insert is designed to consistently impart forward spin regardless of where the ball is hit, whether on the upper or lower part of the face. Furthermore, because the lower part of the insert forms the same surface as the sole, the distinctive shape between the two resin layers, created by AI, can be seen more directly than in the Ai-ONE putter, which has a transparent polycarbonate window.
