Item is Non-Returnable
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 weave that reduces ovaling for better stability during the loading and unloading of the shaft.
The True Temper XP-85 steel shaft is 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.
