The Tech Stack Powering TGL: How FULL SWING Helps Build Golf’s Most High-Tech League

Toptracer: ball-tracing cameras that follow the real shot 

As soon a player makes contact with the ball, Toptracer technology starts to gather data, tracking the actual early ball flight as it travels toward the screen. 

In August 2024, TGL announced Toptracer as its Official Ball-Tracing Partner. 

According to TGL, Toptracer’s camera sensors track ball flights on tee and approach shots hit into the screen and “accurately extrapolate the remaining trajectory” of each shot.  

Golf Digest published an interview with TGL’s tech chief Andrew Macaulay that explains how this works in a very grounded way: Toptracer generates a 3D coordinate path for the ball, while FULL SWING captures data in parallel - and Toptracer provides its flight data to FULL SWING as part of the system.  

So the “virtual ball flight” viewers see isn’t just one technology guessing – its a combined picture built from multiple real measurements.

FULL SWING KIT: data verification 

The FULL SWING KIT is one of the most important technologies in TGL because it helps verify the ball flight data (aka what's happening in the real world) 

TGL’s September 2025 partner announcement states that FULL SWING KIT Launch Monitors will be part of Season 2 gameplay, capturing “accurate moment-of-impact data,” including both ball and club measurements, and confirms these are part of the hybrid mix of technologies for shots hit into the giant screen.  

The ScreenZone features three arrays with 18 launch monitors to ensure accuracy and versatile coverage for right- and left-handed golfers within the real-grass hitting area. 

This matters because impact conditions are where the truth lives: 

In other words: FULL SWING helps generate the performance inputs that make each shot believable and consistent. 

So, while fans see a clean ball flight graphic and a satisfying shot tracer, FULL SWING is part of what makes that data believable in the first place. 

The massive screen: where the virtual course becomes “real enough” 

TGL’s stadium experience depends on one signature feature: the high-definition simulator screen. Players hit into it from a short distance (reported as about 35 yards away in Golf Digest), and the FULL SWING system uses the tracked data to project the ball’s arc and landing result into the virtual environment.  

The screen is accompanied by touchscreen monitors that allow players to preview the hole before playing, allowing them to strategize as they would on course.

The real secret weapon: a transformable putting green 

Here’s where TGL separates itself from “sim golf”: the short game isn’t just virtual. 

TGL uses a physical putting surface – the FULL SWING Virtual Green – which changes between holes.  

The green is the largest-ever-built, transformational putting surface with more than 600 actuators that morph the green’s topography. 

That physical green is a big reason why TGL can still feel like “real golf” under pressure. 

 You can’t hide from putting. 

Broadcast and fan-facing overlays: turning golf into a live data sport 

TGL isn’t only about tracking shots accurately - it’s also about making golf more watchable. 

This is where the tech stack becomes about more than performance - it becomes about storytelling: 

Why FULL SWING’s role is especially important in the stack 

In a hybrid system, the weakest link ruins the illusion. If your data is off, the flight looks wrong. If your ball tracking lags, the shot doesn’t feel live.  

That’s why FULL SWING’s role matters: its technology is woven into the fabric of TGL, from initial verification to shot projection, to real-life putting simulation. 

That collaboration is the tech story of TGL in one sentence: multiple tracking sources, one cohesive shot outcome. 

The big takeaway: TGL isn’t “golf simulator tech” - it’s a hybrid competition platform 

TGL’s tech stack combines: 

And across it all, FULL SWING is repeatedly named as a key technology partner helping the league operate at the level of live professional competition.  

The result is something genuinely new: a golf league where the “course” is built from software, sensors, and real-world surfaces - yet the pressure, execution, and outcomes feel like the real thing.
