Callaway Golf Quantum Mini Driver

The Callaway Quantum Mini Driver is designed as a versatile, 340cc alternative to a standard driver, built to be played comfortably both off the tee and directly from the turf. While its profile looks similar to previous Callaway mini drivers at address, its sole and leading edge have been specifically reshaped to function more like a fairway wood.

To help players pick the ball clean off the deck, it features a sharper leading edge and utilizes the Step Sole Design found in the Quantum fairway woods. This sole geometry minimizes surface resistance and reduces bouncing when making contact with the ground, promoting a smoother strike from tight lies.

At the front of the club, it utilizes the Tri-Force Face. This three-layer construction combines a thin titanium front to handle impact compression, a carbon fiber back to manage tension, and a poly mesh layer to bond them together. This multi-material setup allows the titanium to be machined thinner than in previous models, which helps maintain consistent ball speeds.

Working alongside the physical structure is a Next-Generation AI-optimized face design. By mapping the face thickness to account for real-world impact patterns, it helps control spin variations on off-center hits. This means heel strikes are less likely to balloon upward, and toe strikes retain enough spin to stay in the air, resulting in a more predictable flight.

The head is constructed with a titanium body and a lightweight Triaxial carbon crown to keep the center of gravity low. It is also the first Callaway mini driver to feature the updated OptiFit 4 adjustable hosel, providing an expanded range of loft and lie settings to fine-tune the trajectory.
