Gravity Core Controls Spin

Callaway’s Gravity Core technology was first introduced with the Big Bertha Alpha driver a few years ago and enables the golfer to fine tune the spin profile of the club head with a tungsten end paired with a 1.5-gram nylon end.  By positioning the rod in the head with the heavier tungsten end towards the crown (also known as the high-CG setting), the club will play like a mid-spin driver.   On the flip side, with the low-CG positioning of the tungsten towards the sole, it will decrease spin and increase forgiveness.  The movement of this core weight system can affect the spin rate of the driver’s head by up to +/- 300RPM’s (depending on the player).

Dual Distance Chambers
Looking to dial in the ball flight of the driver? This is where the magic happens. For instance, if you want to hit a straighter shot or draw the ball with more control you know have 2 chambers to choose from. You can also set the Gravity Core up or down, depending upon where you strike the clubface, to generate every last mph out of this driver. Finally, the best of both worlds superior distance and shot-shaping ability.
