If you've ever wondered how do golf simulators work, the short answer is that they let you hit a real golf ball with real clubs into a large screen, while sensors measure your club and ball and project the shot onto a virtual course or driving range with full data. In plain English, a golf simulator turns one room into any golf course in the world — and it reads your swing far more precisely than your eyes ever could outdoors.
If you've never used one, the idea can sound a bit like a video game. It isn't. You take a proper, full swing with your own irons and driver, the ball strikes a tensioned screen a few metres in front of you, and the technology works out exactly what happened — then shows you the flight, the landing and the numbers behind it. This guide explains what's going on behind the screen, what it measures, how accurate it really is, and what it feels like to play.
What is a golf simulator?
A golf simulator is a system that combines a hitting bay, a tracking sensor and golf software to recreate real golf indoors. You swing a real club at a real ball, the sensor captures the shot, and the software plays it back on a virtual course or range. It looks and feels like golf, just under a roof and out of the weather.
At The Golf Cabin in Wick, each bay pairs tour-grade radar with high-speed camera tracking, a 4m x 3m pro impact screen, 4K 6000-lumen projectors, 3.5m ceilings and premium turf underfoot. The result is a life-sized, sharp image of your shot, with full data shown on screen in plain English rather than confusing jargon. Everything is air-conditioned, so a wet or freezing day outside never reaches you.
How do golf simulators work, step by step?
Golf simulators work by capturing your shot with sensors, calculating where the ball would fly, and rendering that flight onto a screen in real time. Radar and high-speed cameras watch the club and ball at impact, software turns those measurements into a true ball flight, and a projector shows the result on a virtual hole or range — all in a fraction of a second.
It helps to break the process into three parts:
- Tracking (radar and cameras): Radar tracks the ball and club through the swing, while high-speed cameras photograph the moment of impact in fine detail. Together they capture how fast the club was moving, where the face was pointing and exactly how the ball came off it.
- The impact screen: You hit into a tensioned 4m x 3m screen a few metres away. It stops the ball safely and doubles as the display surface, so your shot appears life-sized in front of you.
- The software and course render: The system takes the captured numbers, builds an accurate ball flight, and draws it onto a virtual course or range. That's how a shot in a room in Wick can land on a fairway at Pebble Beach.
Because all of this happens almost instantly, the ball seems to fly straight off your clubface into the on-screen world. There's no lag and nothing for you to operate — you just swing, and the shot appears.

Radar or cameras — which do simulators use?
The best golf simulators use both, and that's the key to their accuracy. Radar excels at tracking the ball once it leaves the face, measuring speed, spin and the full flight path. High-speed cameras excel at the split second of impact, reading exactly what the clubhead was doing. Combine the two and the system knows both what you did and what the ball did as a result.
Budget setups often rely on a single sensor and estimate the rest, which is why their numbers can drift. A dual radar-and-camera system, like the one at The Golf Cabin, measures far more directly, so there's less guesswork and the data you see is genuinely trustworthy.
What data does a golf simulator track?
A golf simulator tracks a detailed set of club and ball measurements on every shot, covering both how far the ball goes and how you delivered the club. At The Golf Cabin, these appear on a 4K screen in plain English, so you can actually understand them. Here's what each one means:
| Metric | What it means in plain English |
|---|---|
| Carry distance | How far the ball flies through the air before it first lands. |
| Total distance | Carry plus roll — the full distance once the ball stops. |
| Ball speed | How fast the ball leaves the clubface; the biggest driver of distance. |
| Club speed | How fast the clubhead is moving as it reaches the ball. |
| Smash factor | Ball speed divided by club speed — how cleanly you struck it. |
| Launch angle | The upward angle the ball starts on as it leaves the face. |
| Spin rate | How much backspin is on the ball, which affects height and stopping power. |
| Club path | The direction the clubhead travels through impact (in-to-out or out-to-in). |
| Face angle | Where the clubface points at impact — the main cause of slices and hooks. |
| Attack angle | Whether the club is moving up or down when it meets the ball. |
You don't need to memorise any of these to enjoy yourself. If you'd like a friendly breakdown, our article on your launch monitor numbers explained walks through smash factor, spin and carry in more depth.
How accurate are golf simulators?
Good golf simulators are very accurate, because they measure your real shot directly rather than guessing at it. Tour-grade radar and high-speed cameras capture the actual club and ball, so distances and shot shapes closely match what you'd hit outdoors — which is why simulators are used for serious practice and club fitting, not just for fun.
Accuracy does depend on the quality of the kit and the room. Tour-grade radar paired with camera tracking is far more precise than a single budget sensor, and generous ceiling height and proper turf let you make a natural, full swing. The closer the bay lets you swing as you would on a course, the more trustworthy the numbers. We cover this properly in how accurate golf simulators are.
What does a golf simulator actually feel like to play?
It feels like real golf, with the ball and the strike behaving exactly as they would outdoors — the only difference is that the flight plays out on screen instead of over a field. You feel the same contact through your hands, hear the same strike, and watch the ball rise toward the target. Within a few swings, most people forget they're indoors entirely.
What's different is the feedback loop. Outdoors you squint into the distance and guess. Indoors, every shot comes back with a clear picture and the numbers behind it, so you learn faster and stay engaged. It's also sociable — in a private bay with friends, a simulator quickly turns into a relaxed, competitive night rather than a solitary practice grind.
What can you do on a golf simulator?
On a golf simulator you can play full rounds, practise with purpose, run drills and compete with friends, all from the same bay. It's far more than a driving range substitute — it's a complete golf venue squeezed into one room, usable whatever the weather outside.
Typical things you can do at The Golf Cabin include:
- Play world-famous courses such as Pebble Beach, St Andrews and Wentworth, hole by hole.
- Use the driving range with dispersion plotting, so you can see exactly where your shots are scattering.
- Practise a specific club, distance or swing fault with instant feedback on every ball.
- Play mini-games and competitions that keep mixed-ability groups entertained.
A bay takes up to four players, so it works equally well for a solo session or a night out. You can see the full setup on our golf simulators page.
Can beginners use a golf simulator?
Yes — beginners can absolutely use a golf simulator, and it's one of the most relaxed ways to start playing. You're in a private bay with no audience, you get instant plain-English feedback on every swing, and mini-games make it fun before you know a single rule. There's no dress code at The Golf Cabin, trainers are perfectly fine, and free club hire means you can turn up with nothing at all. If that's you, our guide to whether indoor golf is good for beginners is a reassuring next read.
