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 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 E523 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 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 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.

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

Ultra-Light Premium Shafts -The C523 Iron comes stock with the super-light UST Mamiya HL-SST graphite shaft by that range from 45 to 60 grams depending on the flex. It is also available in a True Temper XP-85 steel shaft.

The UST Mamiya HL-SST shafts feature Stabilized Shaft Tech, a softer tip and a mid-range flex. Stabilized Shaft Tech is an added cross weavethat reduces ovaling for better stability during the loading and unloading of the shaft.

The True Temper XP-85 steel shaftis designed to deliver maximum peak trajectory for explosive distance and are an excellent option for players wanting a higher ball flight with a moderate ball spin.
