Mizuno JPX-800 Irons – First Look

Mizuno JPX-800 IronsMizuno Golf has long been known as a leader in forged clubs. Their forged blades have been very popular with low handicap players for many years and not many other companies can compete with the quality and feel of Mizuno irons. Recently, Mizuno has started to become a more attractive option for the mid to high handicap golfer, with the introduction of the JPX line of irons. Here’s a first look at this new game improvement club.

I’ve spent a few days hitting the JPX-800 irons and I can tell you first off that these irons are long. So far after 18 holes and some time at the range I’ve come to the conclusion that they are about half a club to a full club longer than my current irons. They are also very forgiving. The large face, wide sole and generous perimeter weighting makes these irons easy to hit, but don’t expect much work-ability as this iron was designed for the 8 to 26 handicap range. They simply want to hit the ball high and straight.

Now, let’s hear what Mizuno has to say about the clubs: “A serious looking iron designed to be amazingly forgiving and explosively long, the JPX-800™ is the first model to bring Mizuno’s Global JPX technology platform to the United States. The unbelievable distance of the JPX-800 irons is achieved by combining MAX COR Technology, Hot Metal™ Face construction, and an exotic pocket cavity to hit the maximum allowable limits for energy transfer. Hot Metal™ construction utilizes a new manufacturing process that increases the material’s natural strength to create an ultra-thin and multi-thickness face for maximum, consistent ball speed, while the innovative pocket cavity with external power bar design expands and extends the sweet area and lowers the center of gravity for unsurpassed forgiveness. An aggressive triple cut sole ensures solid ball striking from all types of lies, and a multi-material cavity badge provides tuned impact sound with enhanced feel and sharp looks. Simply put, the JPX-800 irons utilize the world’s most advanced Game Improvement technologies to help the serious mid- to high-handicap player score like never before!”
