Welcome to Fully Equipped’s weekly Tour equipment report. Every Friday of PGA Tour weeks (plus other times, if news warrants), GOLF equipment editor Jack Hirsh runs you through some of the biggest news surrounding golf clubs on Tour, including changes, tweaks and launches.
For the first time in two years, Scottie Scheffler is playing a PGA Tour event without his venerable TaylorMade Qi10 driver.
After months of testing and an initial run last December at the Hero World Challenge, Scheffler has finally put TaylorMade’s latest Qi4D driver in the bag at the Arnold Palmer Invitational this week.
On Thursday at Bay Hill, Scheffler snapped his not-breaking-par-in-an-opening-round streak at three with a 2-under 70. Off the tee, his stats were somewhat middling at first glance as he gained .522 shots on the field (T22), hit 8 of 14 fairways and averaged 303.4 yards on all tee shots.
Those are quite pedestrian for the guy who has been top-two on the PGA Tour in SG: OTT the last four seasons (including 2026) and led the category in 2023.
But looking closer at Scheffler’s radar stats from the 11 times he actually used his new Qi4D driver on Thursday reveals one of his more efficient outings in recent memory.
In terms of accuracy, he hit 6 of 11 fairways with the driver, but four of those five misses were just barely off doglegs in the fairway after the ball landed in the short stuff. Not all misses are necessarily equal.
On No. 6, he obliterated his ball 351 yards just through the fairway on the famous 90-degree dogleg par-5 and left himself just 209 yards to the green. That shot still gained him .02 shots OTT despite finishing in the rough. The other three lost him .28 shots to the field.
When we look at his radar statistics, that’s where things really start to show the improvement.
His clubhead speed was 119.67 mph, actually a touch slower than his season average of 120.5, 34th on the PGA Tour. Despite that, his ball speed was up 180.895 mph, more than 2.6 mph faster than his season average.
Scheffler’s ball speed is faster this season, 178.32, than last year and 2024 at the same point in the year, but a 2.6 mph jump is huge. While there could be many factors at play here, including temperature and other conditions, the fact that this jump came in the first round of using a new driver can’t be overlooked.
His carry efficiency in Round 1 (his carry distance divided by his club head speed) was 2.53, which would be fifth on Tour so far this season. Scheffler was T126 in the stat heading into this week, and he was T110 and T135 the last two years.

His total distance efficiency (total distance divided by club head speed) was 2.62, which would be 63rd on Tour and up from his season average of 2.572.
What does this all mean?
We’ve known this year’s drivers were fast, but now we can see evidence of it.
The fact that Scheffler wasn’t swinging as fast in Round 1, likely a little gun-shy in his first round using the new big stick, yet still increasing his average ball speed by 2.6 mph, is a massive gain. If Scottie Scheffler is picking up 2.6 mph of ball speed, that can’t be good for the rest of the field.
It will be interesting to track as he logs more rounds with the new driver and gets more comfortable with it. With that comfort will probably come more fairways as well.
But there’s a reason Scheffler seemed pleased with his results off the tee with the new driver on Thursday. He specifically called out the spin retention of the new driver on Thursday, which owes to the new, tighter roll radius of the Qi4D face.
“I feel like what we have seen is more consistent spin numbers,” he said. “So that will help it be a little bit more accurate off the tee. Directionally, I struggled a little bit with it at the start of the year, but I got to what I thought was a really good spot last week, and I liked what I saw today.”

Drivers are still unsettled
Scheffler wasn’t the only big name to make a driver switch this week.
Cameron Young switched out of his Titleist GT2 driver for an 11.0-degree GT3 with the same Mitsubishi Tensei 1K Pro Orange 70 TX shaft he had in his GT2. The higher loft of the lower-spinning GT3 head helped him further optimize his numbers as switching to the Pro V1x Double Dot Prototype last summer.
The prototype Double Dot flies lower than his previous Pro V1x, so Young worked with the Titleist team to see what he needed to do to optimize carry with his driver, Titleist Director of Player Promotion J.J. Van Wezenbeeck said.
Working together with Titleist’s Director of Tour Research & Validation, Fordie Pitts, the team determined Young needed a touch more launch. The 11-degree GT3 (lofted down .75˚ in the D1 setting) succeeded in getting launch up from 9 degrees to 11 while only going from 2400 to 2500 rpm spin.

The reason for going to a higher lofted, but more forward CG head was so they could increase the launch without increasing spin. Young led the field and gained 2.277 strokes off the tee in Round 1.
Lucas Glover also added a new Qi4D driver, which is at least his third driver change of the year. That’s similar to Wyndham Clark, who is also most recently in a Qi4D and has played four different drivers this year. And Harry Hall, who earlier this season played a Qi4D LS before switching to Titleist driver, is now playing the core model this week.
Meanwhile, Denny McCarthy added a G440K.
Normally, some of these trivial week-to-week changes would go down in Odds and Ends, but it seems like more players, especially gear free agents, are swapping drivers this season. That’s likely a testament to how good the offerings are; players have taken notice.
“What I’m seeing… heads are a close battle this year,” Fujikura Tour Rep Marshall Thompson told GOLF this week. “It’s very competitive in terms of club speed, dispersion, center-face contact, start direction. There’s not one clear-cut winner from what I’ve seen.
“Even on the Tour side of it, these non-contract guys that I continue to work with on a weekly basis, they still have four or five headcovers in the bag and they’re still trying different options, and we’re already to the Florida Swing.”
