Mizuno Pro 241/243/245 irons

Mizuno Pro Series

Mizuno Pro
A NEW AGE OF FORGING

The foundation of the Mizuno Pro 241/243/245 irons is a unique, long-standing connection between Mizuno’s club engineers and its Grain Flow Forging plant in Hiroshima, Japan. A relationship which enables increasingly sophisticated designs to be crafted flawlessly into finished equipment. Where every fraction of a millimetre and subtle curve matters.

“Other manufacturers have widely adopted Mizuno’s work to elevate the performance of elite player’s irons. What now sets Mizuno apart is the ability to apply precise manufacturing techniques learned at our long-standing forging plant in Hiroshima, Japan, to increasingly complex designs.”DAVID LLEWELLYN – Director of R&D Everything about the new Mizuno Pro 241/243/245 and Fli-Hi is pushed to the extreme – from technology to more streamlined playing profiles. Each model has become better at its specific job, more distinct, yet able to be blended when required.” CHRIS VOSHALL – Product Director

Mizuno Pro 241  / Centre Muscle

The Mizuno Pro 241 is a pure shot-makers muscle-back with mass accumulated centrally behind impact. A result of the pursuit of fine design details made possible through the long-term relationship between Mizuno’s R&D team and its exclusive Grain Flow Forging plant in Hiroshima, Japan.

“With a muscle-back, the gains are in the details. The key to a visually appealing top-line might be a fraction of a millimetre, which can be lost or created in manufacturing. Working hand in hand with our forging plant for so many years allowed us to be incredibly precise in the engineering and craftsman’s stages of the Mizuno Pro 241.” DAVID LLEWELLYN – Director of R&D

Grain Flow Forged HD in Hiroshima, Japan:  One-piece Grain Flow Forged HD from 1025E Pure Select mild carbon steel at Mizuno’s exclusive facility – where Mizuno irons have been produced since 1968.
Soft Copper Underlay:  A microlayer of copper beneath Nickel Chrome – an additional touch to enhance the feel of our Grain Flow Forged heads.
Centre mass for enhanced feedback:   Delivers a softer, longer sensation at impact -matching vibration patterns identified by Mizuno’s Harmonic Impact Technology and confirmed through extensive tour testing.
Aggressively tapered blade:  A more obvious tapering of the upper blade potion delivers an ideal trajectory through the set – with flighted long irons and penetrating short irons.
Thinner, tour preferred topline:  Refined from prior blades through both weight movement within the head and adjustments in final manufacturing.
More compact short irons:  A distinct shortening of the blade length in the shorter irons was a direct request from the majority of Mizuno’s tour players
Increased bounce angle: Increased by a degree in the long irons and 2 degrees in the scoring irons – for improved turf interaction.
Full Satin Brush: A less reflective finish in keeping with the overall modern appearance.

“The muscle-back has re-established itself as Mizuno’s most played model on tour over the last couple of season, so we gave our professional ambassadors a more involved role in the development of the Mizuno Pro 241.  You can see their influence most in the narrower top-line and compact scoring irons.” CHRIS VOSHALL – Product Director

Mizuno Pro 243 / Tour Speed

The Mizuno Pro 243 is a manufacturing masterpiece – more compact and precise than its predecessor, yet faster from the face and more satisfying at impact.  Improvements in performance only made possible through the long-term relationship between Mizuno’s R&D team and its exclusive Grain Flow Forging plant in Hiroshima, Japan.

“The Mizuno Pro 243 is the model that’s advanced the most, mainly due to evolution on the manufacturing side.  It’s one thing for the R&D team to design a thinner face iron with stronger materials in the CAD world – but something else to have it Grain Flow Forged to those specifications and strength requirements.” DAVID LLEWELLYN – Director of R&D

Grain Flow Forged HD in Hiroshima, Japan:  From a single billet at Mizuno’s exclusive facility – where Mizuno irons have been produced since 1968.
4120 Chromoly with Flow Microslot (4-7 iron): A wider, longer micro-slot to create a more expansive high energy area of clubface – resulting in a higher flight and faster ball speeds.
Soft Copper Underlay:  A microlayer of copper beneath Nickel Chrome – an additional touch to enhance the sensational feel of our Grain Flow Forged heads.
1025E Pure Select Mild Carbon Steel 8-GW:  Solid feel and control where most needed, with modern lofts to maintain even distance gapping through the set.
Harmonic Impact Technology:  Applied to closely match the vibration patterns identified with a soft muscle-back feel.
Wrap Around Sole Grind:  Heavy relief around the sole for improved turf interaction and seamless transition from micro slot 7 iron into traditional 8 iron construction.
Exceptionally Compact Players Profile:  Dramatically reduced topline and blade length throughout the set.
Increased bounce angle: Increased by a degree in the long irons and 2 degrees in the scoring irons – for improved turf interaction.
Full Satin Brush: A less reflective, modern finish.

“The Mizuno Pro 243 looks much more compact than its predecessor, even though the performance has stepped up.  The long and mid irons are flying far enough, that we’ve had to modernise the lofts in the scoring irons. Mizuno Pro isn’t stuck in tradition – we’re led by performance above what might be expected historically.” CHRIS VOSHALL – Product Director

Mizuno Pro 245 / Tour Speed and Launch

The Mizuno Pro 245 is measurably quicker again from the face than the Mizuno Pro 243 but also easier to launch – due to a complex hollow body construction and internally suspended Tungsten weight.  Packed into a staggeringly sleek chassis, the Mizuno Pro 245 showcases more than any model how rapidly Mizuno’s Grain Flow Forged process has evolved.

“There’s so much to the Mizuno Pro 245 for an iron of its size and shape.  A multi-piece Grain Flow Forged Chromoly construction, suspended Tungsten weight and multi-thickness face.  Impossible without Mizuno evolving its Grain Flow Forging process in Hiroshima.  It takes a depth of manufacturing experience to push the envelope this far.” DAVID LLEWELLYN – Director of R&D

Grain Flow Forged in Hiroshima, Japan:   At Mizuno’s exclusive facility where Mizuno irons have been produced since 1968.
Hollow body GFF 4135 Chromoly face and neck (2-8 iron):  With multi-thickness face configuration and laser welded 431 Stainless steel back piece for elevated ball speeds and launch. Internal Tungsten Weighting (2-7):  A 46g Tungsten weight is key to delivering improved launch, but is suspended to enable the sole to flex (key to faster ball speeds). More compact partial hollow scoring irons (9-GW):  Laser welded partial hollow construction, GFF HD 1025E body, with 17-4 back piece for a penetrating flight. Soft Copper Underlay:  A microlayer of copper beneath Nickel Chrome – an additional touch to enhance the sensational feel of our Grain Flow Forged heads. Harmonic Impact Technology:  Applied to closely match the vibration patterns identified with a soft muscle-back feel. Traditional blade appearance:  Shaped and proportioned like a classic blade, but sized for performance.
Increased bounce angle: Increased by a degree in the long irons and 2 degrees in the scoring irons – for improved turf interaction.

“There are some impressive ball speed gains in the Mizuno Pro 245, considering we’ve slimmed it down – especially in the longer irons.  The biggest challenge for people now is telling this iron apart from the one piece Mizuno Pro 241 muscle-back.” CHRIS VOSHALL – Product Director

Mizuno Pro Fli-Hi / Tour Long Iron

The Mizuno Pro Fli-Hi has become a fixture with the majority of Mizuno’s tour players.  An easy launching, powerful long iron replacement that flows seamlessly into either the Mizuno Pro 241, 243 or 245 full iron set.  With a chassis now fully upgraded to 4335+ Nickel Chromoly for elevated ball speeds.

“Hybrid type irons generally use a flat sheet metal for the face – but upgrading to a heat treated 4335+ Nickel Chromoloy, allowed us to incorporate a faster multi-thickness face and off-set face weld.” DAVID LLEWELLYN – Director of R&D

Nickel Chromoly 4335+ Hollow Body Construction:  Utilizing a heat-treated multi-thickness face for elevated average ball speeds, with a more pliable body and bendable hosel.
Internal Tungsten Weighting:  23 grams of weight low in the head for elevated launch compared to traditional long irons.
Offset face weld:  Placing the weld line inside the upper face-gauge allowed a thinner topline.  On the bottom edge, the weld line is back from the face, allowing greater flex and ball speeds from low on the face.
Harmonic Impact Technology:  Applied to best match the vibration patterns Mizuno’s tour players identified with a soft muscle-back feel.
Increased bounce angle: Increased by a degree for improved turf interaction.
Black Ion Finish:  Fully blacked-out plating creates the illusion of a more compact profile.

“The Fli-Hi has become a fixture on tour – not just with Mizuno’s contracted players.  The new version is a little slimmer but does everything the original did, just better.  It flights a little higher and goes further.  All obvious improvements – just difficult to make.”
