Callaway Epic Driver
This superb driver benefits from new Jailbreak Technology, which essentially changes the way the head and clubface behave at impact to deliver more ball speed and distance. Jailbreak is 2 strong titanium bars (both just 3g) behind the face, parallel to each other and connected on either end to the crown and sole. The size, strength and location of each Jailbreak bar work together to reduce how much the crown and sole deflect, forcing the face to take on more of the load created at impact than ever before. This results in faster ball speeds across the entire face offering more consistent distances, even on miss-hits.
