These hollow iron-wood designs put a major emphasis on ease of launch, playability and correcting miss-hits and slices to go straighter for the ultimate ease of use. The improved hollow-body design of the Hot Launch E524 Iron features the game-changing Houdini Sole in conjunction with a super-shallow face, slice-fighting offset designs and heel weighting for added draw bias.

Houdini Sole Technology – 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 E524 Iron, making it one the highest launching and easiest to hit irons ever produced.

Hollow-Body Perimeter Weighting - Hollow-body perimeter weighting produces distance properties of a metalwood in an ironlike design. Hollow-body perimeter weighting produces maximum ball speed off an iron. The hollow body design makes for an extremely low and back CG, helping to create a very forgiving and powerful face.

Shallow Face / Offset Design - 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.

New 524 Shaping - New shaping on the 524 Iron includes a wider front to back length, a thinner top line and more weight located lower in the clubhead. What does it do? The lower Center of Gravity in the 524 design leads to a higher MOI that brings more forgiveness and stability to the clubhead, and also increases launch characteristics to make it easier to get the ball in the air.
