The Callaway Big Bertha Diablo fairway woods feature a stainless steel head that incorporates Edge Technology that promotes a higher Moment of Inertia and the center of gravity is optimized through either the Draw or Neutral model to product long, penetrating shots. Edge Technology also allows the golfer to properly release the club through impact for maximum power. Callaway's VFT Technology has also been utilized to increase ball speed and improve forgiveness. The Draw model will help reduce a fade or produce a draw.

• Draw and Neutral Head Shapes
  Provides golfers with the opportunity to select a club that will most benefit their swing type and promote their desired shot shape.
• VFT Technology
  The varying levels of face thickness are designed specifically to maximize performance, resulting in higher ball speed from a larger area of the face to increase distance.
• Edge Technology
  The unique shaping of the all-stainless steel clubheads allowed the engineers to place weight in specific locations to achieve the optimal center of gravity (CG) location and ball flights for the Draw or Neutral options with a higher moment of inertia (MOI). It also helps close the clubface at impact so golfers can better release the club with power.
• S2H2 Design
  Increases discretionary weight by removing it from the hosel and repositioning it in the perimeter of the clubhead to add stability.
