Turbulators, Dragonfly Technology and Vortec Technology
The crown of the G400 Max driver has Turbulators, Dragonfly technology, and Vortec technology. Turbulators are the ridges that run perpendicular to the face. They improve airflow throughout the swing, reducing drag. Dragonfly technology is the finger-like lines that run to the back of the crown. They lower the weight of the crown, optimizing the CG location. Vortec technology on the back of the club also reduces drag during the swing. According to PING, drag is reduced 40% mid-downswing and 15% overall. The PING G400 Max driver also has internal ribs that give the club a solid, muted sound at impact.
