Mizuno Unveils New Pro Series Irons

Mizuno’s new Pro 241, 243 and 245 irons are now available for fittings at the brand’s network of Swing DNA centres across the UK, with assembled custom sets scheduled to ship from early February.

The series includes a muscle back blade (Pro 241), a tour cavity back (Pro 243), and a hollow body construction head (Pro 245), but the new irons have some changes in aesthetics and technology that have made the irons even more desirable.

Mizuno Product Director Chris Voshall said: “Everything about the new Mizuno Pro 241/243/245 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.”

David Llewellyn, Mizuno’s Director of R&D, added: “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.”

PRO 241 IRONS
The Pro 241 is a pure shot-makers muscle-back with mass accumulated centrally behind impact. A more obvious tapering of the upper blade potion delivers an ideal trajectory through the set – with flighted long irons and penetrating short irons.

THE SPEC

Grain Flow Forged: One-piece Grain Flow Forged HD from 1025E Pure Select mild carbon steel.
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.
Set make up: RH: 3-PW / LH: 4-PW.
RRP: £1,200 for 8 club set

PRO 243 IRONS

The Pro 243 is 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 Japan.

SPECIFICATIONS

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.
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.
Increased bounce angle: Increased by a degree in the long irons and 2 degrees in the scoring irons – for improved turf interaction.
Finish: Full Satin Brush
Set make up: 4-GW (RH only).
RRP: £1,200 (8 club set).

PRO 245 IRONS

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