Product Overview: Our highest ever Moment of Inertia driver ever is designed to greatly increase stability for less twisting at impact, which leads to tighter dispersion and straighter shots, improving accuracy off the tee by leaps and bounds. This 460cc driver is absolutely loaded with game-changing innovation, including an all-new Flight Tuning System, 360° Ridgeback technology and 3D Diamond Face technology. Features: 10K MOI Forgiveness Tour Edge’s highest ever Moment of Inertia rating based on the combined horizontal and vertical MOI of the clubhead that surpasses 10,000 g-cm2.10K MOI greatly increases stability for less twisting at impact, which leads to tighter dispersion and straighter shots, improving a golfer's accuracy off the tee by leaps and bounds. Flight Tuning System This all-new Flight Tuning System features an 18-gram weight at the extreme trailing edge on the sole of the clubhead that is easily able to move to the Draw, Neutral or Fade weight ports that have been designed for the 725 series. Moving the back weight to the different weight ports allows for a +/- 7-yard heel and toe bias in directional flight. For example, if you were to move the weight to the Fade weight port, your flight would adjust 7 yards to the right for a right-handed player, and vice versa for the Draw setting. 360° Ridgeback Technology Tour Edge engineers employed the Ridgeback Titanium brace for the E725 features increased structural properties and 360o perimeter weighting. The 360o Ridgeback wraps around the entire perimeter to frame the entire clubhead. This Ridgeback 360-degree brace acts as a brace for the entire clubhead to produce more power across the entire face, including the extreme perimeters. Adding additional Titanium to the entire perimeter with a thicker ridge at center face allows more support on off-center hits to increase face deflection. 3D Diamond Face New 3D Diamond Face is made up of new three-dimensional shapes of variable thickness located behind the face, bringing the face to life with full depth and height of the Diamond shapes being utilized. 3D Diamond Face coverage removes additional weight from the face and dramatically increases ball speed on off-center hits while also greatly aiding forgiveness strikes to the extreme heel and toe of the clubhead. There are 61 total diamond shapes feature on 3D Diamond face, comprising seven different 3D thicknesses in an interweaving pattern. The mini-trampolines that make-up 3D Diamond Face create faster ball speeds and an expanded sweet spot, while the reduction in face thickness on the heel and toe adds forgiveness on mishits and dramatically increases ball speed on off-center hits. Power Channel A new Power Channel has been incorporated into the 725 design directly behind the face on the sole of the clubhead. The Power Channel creates better weight distribution and increased face flexing and delivers amplified ball speed and less spin, as well as added forgiveness on shots struck lower on the face. Finned Internal Ribbing Upgraded acoustic engineering is achieved through Finned Internal Ribbing strategically placed on the inside of the clubhead. Internally, the finned ribbing bounce sound on the inside of the club head to provide top-shelf sound and feel.
