Pebble Beach, CA
Callaway Golf’s prototype Quantum TD-TD driver made a notable debut on the PGA Tour this week, with professional golfers Min Woo Lee and Kevin Yu putting the new club into play at the AT&T Pebble Beach Pro-Am. The introduction of this driver was featured in a recent Tour equipment report, highlighting its immediate impact on the professional circuit.
Performance Highlights at Pebble Beach
Australian golfer Min Woo Lee, known for his powerful driving, opted for the Quantum TD-TD driver and immediately saw positive results. Following testing, a change to a Fujikura Ventus Black 7-X shaft with VeloCore+ technology significantly reduced his spin rate by approximately 300 RPMs and tightened his overall shot dispersion. This adjustment allowed Lee to achieve a much better start line, optimized spin rate, and improved down-range pattern, ultimately enhancing his ability to capitalize on his length. In the first round at Spyglass Hill, Lee gained 0.648 strokes off the tee. Kevin Yu also adopted the Quantum TD-TD driver, experiencing a seamless transition with consistent ball speed, spin rates, and launch dynamics compared to his previous models. Yu notably gained nearly 0.8 strokes off the tee during the first round at Pebble Beach.
Understanding the Quantum TD-TD Driver Technology
The Quantum TD-TD driver is part of Callaway’s latest Quantum family, which has been making its way onto the PGA Tour. The “TD” in its name, standing for “Triple Diamond,” indicates a design geared towards skilled players seeking lower spin and greater workability. This specific prototype is characterized by a compact head profile and reduced face progression, which creates a more neutral start line, assisting players like Lee with a favored pull cut shot.
Innovative Tri-Force Face and Ai Smart Face
A key innovation in the Quantum driver lineup is the revolutionary Tri-Force Face. This advanced face technology incorporates three distinct materials: ultra-thin, high-strength titanium for pure speed, a military-grade poly mesh that binds the layers, and carbon fiber to reinforce the face structure, allowing for greater flex. The design of the face also leverages Callaway’s next-generation Ai modelling, known as Ai Smart Face. This technology uses real player data, including swing speed, club delivery, and face orientation before impact, to optimize launch and spin consistency. The Ai Smart Face creates micro deflections upon contact, effectively producing multiple sweet spots across the face to optimize performance even on off-center strikes.
Advanced Construction and Adjustability
The Quantum TD-TD also features an updated 360° Carbon Chassis, which includes a new internal titanium support structure. This construction reduces overall weight, allowing for strategic redistribution of mass to enhance forgiveness and improve launch dynamics. The driver incorporates adjustable sole weights, providing golfers with the ability to fine-tune spin rates and ball speed. Furthermore, an adjustable hosel allows for personalized loft and lie adjustments, enabling players to customize the club to their specific preferences and achieve optimal ball flight. The Quantum TD-TD driver, along with other Quantum heads, was added to the USGA conforming list last fall.
Broader Tour Adoption of the Quantum Family
The introduction of the Quantum TD-TD driver at Pebble Beach follows earlier sightings and adoptions of other models within the Quantum Triple Diamond platform on the PGA Tour. At the WM Phoenix Open (February 5-8, 2026), golfers Nicolai Hojgaard and Si Woo Kim both transitioned to new Callaway Quantum Triple Diamond drivers. Hojgaard opted for the Triple Diamond Max model, while Kim chose the more compact Triple Diamond version. Nicolai Hojgaard is an active player on both the PGA Tour and the European Tour. Si Woo Kim has publicly confirmed his commitment to remaining on the PGA Tour, dispelling rumors of a move to LIV Golf. The Quantum family also includes prototype Quantum Mini drivers and Ti fairway woods, which have garnered attention on Tour.
