FROM OUR EXPERIENCE
When someone comes to us for the first time with a budget and a vague idea of ‘building a simulator,’ the first thing we do is walk them through the full component list — not to sell them everything, but because understanding what each part does is what makes every subsequent decision logical rather than arbitrary. This guide is that conversation in written form.

This guide is that conversation in written form.
A golf simulator looks simple from the outside — swing, ball hits screen, shot plays out. But the experience is the product of a dozen or more distinct components, each performing a specific function. Knowing what each part does, why its quality matters, and how it interacts with the rest of the system is the foundation of every good build decision.
1. The Hitting Mat
The hitting mat is the physical foundation of the build — the surface you stand on and strike from. Quality hitting mats include a tee zone with an adjustable rubber tee for woods and drivers, a fairway surface for iron play, and often a rough panel for specialty shots.
Mat quality directly affects joint health over time. According to sports medicine research published in the Journal of Sports Science & Medicine, repeated impact on hard artificial surfaces is a contributing factor to wrist, elbow, and shoulder stress injuries in practicing golfers. Mats with adequate cushioning under the turf surface absorb much of this impact energy, making extended sessions physically sustainable.
2. The Impact Screen
The impact screen is the large fabric panel the ball strikes — simultaneously the projection surface for the virtual course and the primary safety barrier between your golf ball and the wall behind it. Premium multi-layer screens (like TruSim’s Elite and High Contrast lines) use bonded constructions where each layer has a distinct function: projection performance on the front, energy absorption in the middle, and wall protection at the rear.
The screen is the system’s primary consumable — expect replacement every 3-7 years under regular home use depending on shot volume and material quality.
3. The Enclosure and Truss System
The truss is the skeleton of the bay. TruSim’s TruTruss XT™ is a modular aluminum system that holds the screen in precise position, provides mounting points for all hardware, and can be disassembled and relocated. The precision of the truss — how square, level, and rigid it is — directly affects screen tension consistency, projection alignment, and ball response.
4. Screen Tensioning Hardware
The screen attaches to the truss via a tensioning system that must hold the fabric under precise, even tension at all times. TruSim’s TruStrap™ (strap-based), TruGrom™ (grommet-based), and TruGrip™ XL (hook-and-loop) systems provide different tension control approaches for different screen types and usage patterns. The right tensioning system is matched to the screen type and how permanent the installation is intended to be.
5. The Launch Monitor
The launch monitor is the measurement device that makes simulation possible. It captures ball speed, club head speed, launch angle, spin rate, spin axis, smash factor, face angle, and club path in milliseconds of impact — and sends that data to the simulation software. The precision of these measurements is what the simulation’s accuracy depends on.
Technology types: radar-based systems (Trackman, FlightScope) use Doppler radar to track ball flight; camera-based systems (Foresight GCQuad, GC3) photograph the ball microseconds after impact; overhead systems combine technologies from above the hitting zone. Each has strengths in specific measurement areas and is optimized for different room configurations.
6. The Projector
The projector displays the virtual course on the screen. Short-throw and ultra-short-throw models are standard for simulator applications — they fill a large screen from the limited throw distance available in most rooms. Key specifications: brightness (ANSI lumens), resolution (1080p minimum, 4K for premium builds), throw ratio (matched to room depth and screen size), and light source (lamp vs. laser — laser units have 20,000+ hour service lives versus 2,000-5,000 hours for lamp-based units).
7. The Simulation PC and Software
Simulation software runs on a gaming-grade PC and receives launch monitor data in real time, applies physics models, and renders ball flight on 3D course models. Popular platforms include E6 Connect, GSPro, and TGC 2019. Most platforms license real course data — the green undulations and fairway contours are based on actual survey measurements of the real courses.
8. TruBack™ Performance Backer
A secondary fabric layer mounting between the primary screen and the wall. Absorbs residual impact energy, protects the wall surface, reduces ball rebound velocity, and extends primary screen life by sharing the impact load. Essential in commercial settings; a high-value addition in residential builds.
9. TruGuard™ Overhead Mesh
Physical containment installed across the ceiling of the bay to catch upward shots. Protects overhead hardware, lighting, and structural elements from ball impact. Required in most commercial facilities; strongly recommended in any residential bay with exposed ceiling components.
10. Performance Drapes and Acoustic Panels
Performance Drapes hang at the bay sides, providing side containment and ambient light absorption simultaneously. Acoustic Wall Panels on side and rear surfaces absorb reflected sound energy, dramatically reducing the reverberant, fatiguing acoustic character of a hard-walled simulator room.
How Every Component Works Together
You swing. The ball contacts the screen. The launch monitor captures shot data in milliseconds. The simulation PC processes it and renders the virtual shot. The projector displays the result on the screen. TruBack™ absorbs residual energy behind the screen. TruGuard™ is there if the shot goes up. Performance Drapes catch anything that goes sideways. Every component has a role. The quality of the experience is determined by the weakest link in the chain.
Frequently Asked Questions
Which component should I invest in most?
The launch monitor and the impact screen are the two highest-priority investments. The launch monitor determines data accuracy — the foundation of practice value. The screen determines both the visual experience and safety. These two should not be compromised in favor of spending more on the projector or software.
Can I add components over time, or do I need everything at once?
You can build incrementally. A common approach: start with the core (launch monitor, screen, enclosure, projector, software), then add acoustic panels, performance drapes, and TruGuard™ as budget allows. TruBack™ is worth adding at the initial build given its low cost relative to the wall protection it provides.
What’s the component that most often gets forgotten?
The hitting mat is the most frequently under-budgeted component. Buyers spend carefully on the launch monitor and screen, then choose a thin $150 mat and spend years hitting off a surface that’s bad for their joints and doesn’t feel like real turf.
