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 in ease of use.

The improved hollow-body design of the Hot Launch E523 Iron features the game-changing Houdini Sole in conjunction with a super-shallow face, slice-fighting offset designs, and heel weighting for an added draw bias.

HOUDINI SOLE TECHNOLOGY

The Houdini Sole is a raised steel mass area at the rear of the club head, 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 of 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 iron-like 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 is 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.

CONCAVE BODY DESIGN

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 the address, while still providing the forgiveness and ease of launch that our iron-woods have become famous for.
