E523 HYBRID Houdini Sole Technology includes an area of mass concentrated on the trailing edge of the sole of the clubhead, as well as a curved leading edge under the face. Unique and patented sole design allows engineers to precisely position weight in the head for an ultra-low and deep CG, optimizing launch conditions and greatly improving stability. Offset designs are combined with a heel sole weight to provide the ultimate in slice fighting technology. The offset design of the E523 Hybrid added with a heel sole weight allows the face to square up at impact for straighter ball flight. Diamond Face Variable Face Thickness technology is a breakthrough in face technology that features 39 different thick and thin diamond shapes or “mini-trampolines” behind the face Diamond Face VFT produces a hotter face with faster ball speeds and better performance on off-center hits, as well as reduced spin. The super-shallow face coupled with a larger footprint design in the Hot Launch E metals are designed for extreme playability and high-flying launch characteristics. The larger hybrid design with an extremely shallow face produces higher launch angles and extreme ease of launch with extreme forgiveness. E523 IRONS The Houdini Sole is a raised steel mass area at the rear of the clubhead, as well as a curved leading edge under the face. The patented Houdini Sole reduces the amount of sole area to reduce drag and turf interaction by 35% and is instrumental in significantly altering the CG placement of the E523 Iron, making it one the highest launching and easiest to hit irons ever produced. Hollow-body perimeter weighting produces distance properties of a metalwood and maximum ball speed of an iron. The hollow-body design makes for an extremely low and back CG, helping to create a very forgiving and powerful face. The super-shallow face coupled with an offset design are designed for extreme playability and high-flying launch characteristics. The offset design acts as built-in slice fighting technology, squaring the clubhead at impact to produce anti-slice ball flights. The extremely shallow face produces higher launch angles and extreme ease of launch with extreme forgiveness. A new concave design added to the E523 Iron creates our best-looking hollow-body iron-wood to date. The concave treatment to the shape of the E523 Iron creates a smaller topline, and a less visible backend for a more compact look at address, while still providing the forgiveness and ease of launch that Tour Edge’s iron-woods have become famous for.
