Mizuno JPX-850 Driver
In 2007 Mizuno introduced a sliding weight system called Fast Track - to alter a driver's draw/fade tendency. Mizuno has now evolved this breakthrough technology to also be able to customize spin rate and launch angle in the JPX-850 - helping all swing speeds achieve maximum possible total yardage. A massive playing profile with a low and deep extended weighting system launches the ball into an optimized, low spinning orbit - from whichever QuickSwitch setting you choose.
The piercing blue JPX-850 uses twin 8-gram weights which can be located on either the central sliding rail, or two lateral slots. With 10 unique settings, players of all head speeds can dial in their perfect launch and spin.
In combination with Mizuno's Quick Switch shaft release system, the JPX-850 also offers lofts from 7.5 to 11.5 within one head for the ultimate in adjustability.
The JPX-850 head is a compact, powerful 440cc Titanium driver that utilizes a Rebound Crown to maximize ball speeds for unmatched distance.
"The genius of the new Fast Track is that it adds the dimension of launch angle and spin rate. Now the player is truly in control of maximizing all aspects of their ball flight off the tee."
