New Mizuno Pro irons: What’s New

Mizuno have announced the successor to the popular Pro 22 series by introducing the new Pro 241, Pro 243, Pro 245, and Pro Fly Hi irons.

The series includes a muscle back blade, a tour cavity back, and a hollow body construction head that is featured in the Pro 22 series, but the new irons have some changes in aesthetics and technology that have made the irons even more desirable.

Mizuno say that because of their long relationship with the grain flow forging plant in Hiroshima, Japan, they are able to challenge the boundaries when designing and putting together a forged head. But what is different? Let’s have a look at the different models.

Mizuno Pro 241 irons

Historically, Mizuno have made some of the best blade irons of all time, and given the heads are small, it can be hard to make any groundbreaking technology changes. This year, however, Mizuno have built on what was already an excellent head in the Pro 221 and have made some serious developments.

The Pro 241 is once again made from forged one-piece 1025E steel, but this time, the head has been designed with more centred mass for a better feel and enhanced feedback. It has a new sole design for better turf interaction. Like all Mizuno Pro iron models, the 241 has a soft copper underlay beneath its nickel chrome finish.

The big news is that after tour player feedback the heads have gotten smaller, only slightly in the long irons but quite aggressively in the short irons.

The classic blade has gotten even more classic; if you are a blade lover, you are going to like these irons.

Mizuno Pro 243 irons

If you want a classic-looking iron but can’t quite bring yourself to play the pure blade, the Mizuno Pro 243 iron is a great option. Again, it is smaller and more compact than its predecessor, but the technology in this iron is amazing.

Again made from one piece of metal, these irons feature springier, faster 4120 chromoly steel from 4-7 iron and switches to the 1025E from 8-GW. A move that ensures golfers get higher launch and faster ball speeds for longer approaches, along with more feel and control from nearer the green.

It has a thinner face than before, making ball speeds hotter, and it has a progressive micro slot in the sole that gives a higher launch and more forgiveness. It also has a shorter blade length and, a new sole design that helps blend the irons that have a micro slot with the irons that don’t and improves turf interaction.

These irons move into the ultra-competitive market that features the Titleist T100, the TaylorMade P770 and Callaway Apex CB iron, but we are with Mizuno’s exceptional forging history they are going to be fighting for top spot in that category.

Mizuno Pro 245 Irons

The Mizuno Pro 245 is a hollow body iron head that features an internally suspended tungsten weight. This makes the irons longer, faster and easier to hit than the Pro 243 head, but there has been no sacrifice of aesthetics for this performance; these irons look like a blade when in your golf bag.

Mizuno have improved the way the tungsten sits in the head which has lowered CoG and increased COR. All you need to know about these acronyms is that the irons are now longer and higher launching than the previous model.

The heads feature the same soft copper underlay that all the Pro 24 irons have, but like the Pro 243 irons the longer irons are the springier chromoly steel and the shorter irons are 1025E. The head size of this iron has also reduced so looks more compact and like a players iron than before.

These are the irons you want in the bag if you want both player’s looks and also maximum distance, the performance of these irons is very impressive.

Mizuno Pro Fli-Hi

The Mizuno Pro Fli-Hi iron has legendary status in golf. Most driving iron users have had one in the bag at one time or another, and nearly all of Mizuno’s tour players have one in the bag, so it has been difficult to improve something that already performs really well.

The head is now smaller than before; there is 23g of tungsten low in the head to lower centre of gravity, making it easier to launch. The Fli-Hi has a new hot metal ultra high strength heat treated 4335+ Nickel Chromoly multi-thickness face that is faster from all strike locations than before, making it more playable than ever. It also has an improved sound so your playing partners know you have really striped it.
