An aerodynamic apparatus that is built into or attached to a body of a golf club head to cause the airflow over the body to transition from smooth to turbulent at a defined length from the striking face of a club. The device reduces asymmetric variations in the boundary layer separation point that cause unsteady forces on the club head and create excess unpredictable cavitation behind the club head. The device is aligned essentially parallel to the intersection of the striking face and the body and is situated near the maximum thickness of the body cross-section. The device is comprised or a small strip of material, a string, a gap, a ridge, a groove, a step up, a step down, a surface curvature breakpoint, or a series of geometric patterns that traverses around the entire perimeter of the body surface either continuously or in broken segments.
