How Does Trackman Improve My Golf Swing? (The Honest Answer From a PGA Professional)

By Kevin Delaney | Project Golf London | kevindelaneygolf.com

Let me ask you something. If you've been slicing the ball for three years, taking lessons, watching YouTube videos, making adjustments — and you're still slicing — what's the one thing you haven't tried?

The truth.

Not somebody's opinion. Not a feel. Not a guess based on what your swing looks like from the outside. The actual, undeniable, measurable truth about what's happening at the moment your clubface meets the ball.

That's what Trackman gives us. And in my years coaching golfers of every level right here in central London, it has completely changed the way I teach — and more importantly, how quickly golfers improve.

X-Ray Vision for Your Golf Swing

When I introduce a new student to Trackman, I describe it like this: it's X-ray vision into your impact.

Video can show you what your swing looks like. Trackman shows you what your swing is doing. There's a big difference. You can have a swing that looks textbook-perfect on camera and still be losing distance, missing left, or spinning the ball into trouble — because what happens in that split-second of impact is invisible to the naked eye.

Trackman uses dual-radar technology to track everything: where the clubhead is travelling, where the face is pointing, how fast you're swinging, how the ball launches, how it spins, and where it lands. Over 26 individual data points, every single shot.

It sounds technical. And yes, some of it is. But here's what I love about it as a coach — it takes the guesswork out. For both of us.

The Myth I Bust Almost Every Week

Here's something I hear constantly, from beginners and experienced players alike:

"I hit the ball far enough — I just need to work on my accuracy."

I understand why people feel this way. Distance is easy to measure. You can see roughly how far the ball went. Accuracy feels like the puzzle to solve.

But when I put those golfers on Trackman, almost every time, the data tells a different story.

Their smash factor — the ratio of ball speed to clubhead speed, basically a measure of how efficiently they're transferring energy into the ball — is often sitting well below where it should be. A driver swing speed of 95mph should produce around 220mph of ball speed. But if that smash factor is low, they might only be getting 200mph. That's 15 to 20 yards of distance quietly disappearing, shot after shot, round after round.

And here's the thing: those lost yards can't be reclaimed by "being more accurate." They're gone because the strike isn't clean. Fix the strike, improve the smash factor, and suddenly they're hitting the ball further and straighter — because centre-face contact does both at once.

Without Trackman, we'd never know. With it, it's right there in front of us. If you want to find out exactly where your game stands before your first lesson, you can complete a player assessment form here — it helps me hit the ground running on day one.

The Data Point That Changes Everything

If I had to pick one Trackman number that genuinely transforms a golfer's understanding of their own swing, it would be the relationship between club path and face angle.

This is where things get interesting. And where a lot of well-meaning advice falls apart.

Most golfers who slice the ball have been told at some point: swing more to the right, stop coming over the top, get the club more from the inside. And there's truth in that — club path matters. But path is only half the story.

The direction the ball starts is determined almost entirely by where the face is pointing at impact. The curve of the ball — the slice or draw — is caused by the relationship between face and path. So you can have a perfectly inside-out path and still slice the ball horribly if your face is open. And that's exactly what I see all the time.

I had a student come to me not long ago — a committed slicer. Years of trying to fix it. He'd been working on his path for months. Swinging more from the inside. Trying to hit draws.

Still slicing.

We put him on Trackman. His path? Actually fine. A touch outside-in, but nothing dramatic. His face at impact? Open by 7 degrees. Every. Single. Shot. His face was the problem, not his path. Once we saw that clearly, we stopped working on what wasn't broken and focused entirely on what was. Within a few sessions, the slice was gone. Not reduced — gone.

That's the power of data. It points you at the real problem.

It Works for Every Golfer — Not Just the Serious Ones

One thing I'm proud of at Project Golf London is the range of golfers I work with. Complete beginners on their very first lesson. Mid-handicappers chasing single figures. Competitive players preparing for tournaments. Professionals looking to sharpen up.

Trackman works for all of them — differently, but equally effectively.

For a beginner, it removes the confusion. Instead of being overwhelmed with swing theory, they can see immediately what the ball is doing and why. The feedback is instant and visual. It makes learning faster and, honestly, more enjoyable.

For an experienced golfer, it gets underneath the habits they've built up over years. It doesn't care how long you've been playing. It just tells you what's happening.

And for every golfer in between, it creates something really valuable: accountability to the truth. You can't argue with the numbers. You can't blame the wind or the mat or the grip. The data is right there, and it makes the path forward obvious.

Send me your swing, I'll analyse it with the same level of detail and give you a personalised action plan — wherever you are in the world.

It's a zero-risk way to find out exactly what's holding your game back.

So, Does Trackman Actually Improve Your Swing?

On its own? No. A machine doesn't improve your swing. A great coach with a great machine does.

What Trackman does is remove the fog. It replaces guesswork with clarity, trial-and-error with precision, and vague feelings with concrete measurements. It means that every minute you spend in a lesson is spent working on the right thing — the real problem, not the symptom.

In a busy city like London, time is precious. My students don't want to spend six months going in the wrong direction. They want to improve, and they want to understand why they're improving. Trackman makes both of those things happen faster.

If you're curious what your numbers look like, or if you've been working on the same problem for a while and not seeing results, come and have a lesson at Project Golf London. Let's take a look under the bonnet together.
