Features and benefits of the Callaway Diablo Octane Black driver:

• Revolutionary new material that's lighter and stronger than titanium.
• New carbon fibres all engineers to precisely control thickness, resulting in a club head that's lighter but still has a high Moment of Inertia.
• Chemical milling selectively removes excess material for precison thickness across the face producing high ball speeds for long distance.
• Dark Physical Vapor Deposition Finish comes from a high-tech process that produces a distinctive, non-glare finish.
