A “Quantum Leap” in greens hit in regulation…
By Tim Graves, PGA
We’ve been talking with Patrick Davis (Callaway Engineer whose team was responsible for designing the Quantum clubs) about the new Quantum Golf Clubs with the Modern 360 Undercut that gives you 6 to 10 extra yards on mishits ...
But there’s a second technology in these irons that’s just as important.
It’s called the Tri-Sole Design.
And when Patrick explained it to me, I immediately thought, “This is why players are going to feel more confident over the ball” and “Why getting so many positive testimonials already“.
The Tri-Sole is a progressive keel and chamfer that runs down the front half of the sole. It changes through the set—your 4-iron has a different sole design than your 9-iron.
The key feature? It lifts the leading edge off the ground.
Patrick told me, “We noticed players having better games than we anticipated, which doesn’t always happen. We’re excited when it happens, but as engineers, we’re gonna go, why?“
So Patrick and his engineers interviewed the players who tested these irons.
Here’s what the players said: “I feel like I can get down on the ball more because I’m not catching as much turf.“
“I feel like I can swing harder because my divot pattern’s just a little bit cleaner and I’m making better contact.“
“I’m building confidence.”
The irons made them feel like they could be more aggressive.
And here’s the data that backs it up …
Patrick’s team saw impact locations rise about one full score line during testing.
One full score line.
That means more center-face contact. More of those “crisp” feeling shots. Fewer thin hits off the leading edge.
Meaning – if you hit the irons a little thin (minimal divot) you will not lose much distance…. much less then before with other clubs.
Patrick said, “We can put all the AI at face. But if the consumer doesn’t perceive the club as easier to hit, easier to launch, they’re never gonna have the confidence when they pick it up.“
This is where perception meets performance.
The Tri-Sole makes the club FEEL easier to hit. And when you feel confident, you play better.
Now here’s the question everyone asks me, “Tim, which Quantum iron model should I get?“
Callaway makes three models. Let me break them down for you.
1. Quantum Max
Patrick described it as “kind of smallest, most compact” of the three models.
It’s got a medium-width sole.
Who it’s for: Players who take a divot and want forgiveness without a huge, chunky look.
2. Quantum Max OS
The “OS” stands for Oversized.
Patrick told me, “This is the Big Bertha vibe. It’s got a wider sole. It’s got more offset. It’s got a bigger head. It’s got a thicker top line.”
He also said, “Everything’s about confidence and launch in this club.”
The wider sole helps you get the ball in the air even if you don’t take a divot or minimal divot. You can bounce it. You can skip it. You don’t even need to use the turf—you’re still going to benefit from this design.
Who it’s for: Players who make minimal to no divots and need help getting the ball in the air. This is the model I recommend for most Single Plane golfers who don’t make a divot.
3. Quantum Max Fast
This is the lightweight iron. The entire platform is 20% lighter.
Why does this matter?
If you’ve lost swing speed over the years—and let’s be honest, we all do—this iron helps you get that speed back.
Patrick said, “That doesn’t mean they’re a beginner golfer. It’s maybe somebody that’s lost speed over the years that’s trying to find that back.”
Who it’s for: Senior players, lady golfers, or anyone who’s lost 5-10 mph of swing speed and wants to regain distance.
Here’s the key …
If you make NO divot or a very minimal divot, we’re going to recommend the Max OS or Max Fast (depending on your swing speed).
If you make a divot, we’re going to recommend the Max.
The sole width, the offset, the weight distribution—it all matters based on how YOU interact with the turf.
Patrick holds up all three iron models and shows you the sole differences, the top line thickness, and exactly who each model is designed for.
