The Philosophy Behind Complete Inertial Design
Callaway Golf designers consider all of the club’s characteristics collectively and create a design that balances those characteristics and optimizes performance. The key is to avoid focusing on one characteristic at the expense of the overall performance of the club.

What CID Means to You
The goal of making clubs perform well on off-center hits applies to irons as well as woods. Using CID helps achieve a high performance ball flight even when you don’t hit the ball in the middle of the clubface. Distance and direction will be retained due to minimal clubhead movement during impact.


Clubhead Stability
One element of CID is increased stability of the clubhead, which is measured in terms of MOI. By raising the MOI on both the vertical and horizontal axes and by positioning weight to the perimeter of the clubhead, Callaway Golf engineers are able to create unprecedented stability on balls struck around the entire face. That means less clubhead twisting at impact on those off-center hits. Because the clubhead rotates less, (1) loss of ball speed is minimized and the ball goes longer, and (2) the ball goes straighter on off-center hits compared to standard driver designs.

Center of Gravity Location
Positioning the CG in an optimum location within the clubhead is another crucial element to CID. It’s done for several reasons: (1) to optimize trajectory, leading to maximum distance; (2) to optimize the clubhead for a draw, neutral or fade bias depending on your swing type; and (3) to optimize the clubhead for elite players allowing them to produce certain shot shapes.
