Players Distance Driver

The Mizuno JPX-850 driver from 2015 is the club Mizuno built when it decided to take the driver market seriously. Mizuno's reputation was forged in forged irons, and for years the driver was an afterthought. This one wasn't. It packs a 460cc head, an adjustable Quick Switch hosel, and a pair of moveable weights on the sole that let you dial in shot shape and launch. For a company known for buttery blades, that's a lot of gear-head hardware in one head.

The headline here is adjustability paired with high launch. The face is thin and hot, and the weighting biases the ball into the air, so if you fight a low, spinny ball flight or just want easier carry, this driver leans your way. Move the weights toward the heel and you can fight a slice. Slide them back and you add stability. The hosel lets you tweak loft and lie without a trip to the shop.

Don't confuse the JPX name with a niche release. The 850 was aimed at the widest swath of golfers Mizuno could reach, from mid handicappers who want forgiveness to better players who like the tuning options. It launched high, it was loud enough to feel fast, and it gave Mizuno loyalists a driver they no longer had to apologize for.

• You hit the ball too low with your current driver and want more carry without swinging harder.
• You like to tinker. The moveable weights and adjustable hosel reward players who enjoy tuning their setup.
• You play Mizuno irons and want a driver from the same family that finally holds its own off the tee.
• You need help fighting a slice and want a driver you can bias toward a draw.

Frequently Asked Questions

Is the Mizuno JPX-850 driver good for high handicappers?

Yes. The 460cc head, perimeter weighting, and high-launch design make it forgiving on mishits, and you can slide the weights toward the heel to help straighten out a slice. It's an easy driver to get in the air, which is exactly what a lot of higher handicappers need.

How do the moveable weights on the JPX-850 driver work?

There are two weights on tracks in the sole. Move them toward the heel for a draw bias, toward the toe for a fade bias, or keep them back for a neutral, more stable, higher-launching setup. It takes a torque wrench and a minute, and the change in shot shape is real, not just cosmetic.

What lofts does the JPX-850 driver come in?

It was offered in the usual driver lofts, and the Quick Switch adjustable hosel lets you fine-tune loft and lie from the base setting. If you're between lofts, buy the one closest to your carry needs and adjust from there.

Does the JPX-850 driver launch too high for faster swing speeds?

It can if you leave it in the highest-launch setup. Faster swingers who spin the ball a lot should set the weights back, dial the hosel to a lower loft, and pair it with a lower-launch shaft. Set up that way, it stays playable for stronger players.

Is the Mizuno JPX-850 driver still worth buying today?

As a used or budget pickup, yes. You give up some of the ball speed and forgiveness gains newer drivers have made, but the adjustability and high launch still hold up, and prices on the used market are low. If you want a tunable, easy-launching driver without paying current retail, it's a smart buy.
