The form factor seats directly on the unit — no tools, no drilling, no hardware required. It is designed to absorb or deflect accidental ball and club contact before it reaches the launch monitor housing. If the shield takes a direct hit doing its job, Elite Sim Golf will issue a replacement under the lifetime replacement guarantee. Patent pending design, manufactured in-house by Elite Sim Golf — not sourced from a third party. Patent Pending — The one-piece thermoformed polycarbonate form factor is a patent pending design engineered specifically for the VTrack housing. This construction is not available from any other supplier. View Impact Protector → Built to Work Together Overhead Tracking and Short-Throw 4K — Engineered for the Same Bay The VTrack sits overhead at the ceiling. The ZK521ST-B mounts at the rear of the bay, throwing forward toward the screen. ESG has vetted and confirmed these two components work flawlessly together — this pairing was built from the ground up for the same overhead bay. No Floor Clutter VTrack overhead means nothing sits in the hitting zone. The ZK521ST-B rear-mounts to the ceiling — no floor tripods, no cords crossing the mat, no obstacles between the player and the screen. Matching Data Quality 5,000 lumens keeps the 4K image vivid at the resolution the VTrack’s data deserves. Crisp course visuals and precise shot data reinforce each other. 25+ tracked parameters rendered at 4K UHD — neither component is a bottleneck. Shared Software Ecosystem Both components are compatible with GSPro and E6 Connect. One software environment, two hardware components, no compatibility workarounds. VTrack also supports E6 Apex; the ZK521ST-B Golf Sim Mode is pre-tuned for all three. Vetted Compatibility ESG has vetted and confirmed the VTrack and ZK521ST-B work flawlessly together in an overhead bay setup. The 0.79:1 rear-mount position and the VTrack’s overhead bracket are designed to coexist without conflict. Use the ESG Projector Fitment Tool to dial in your exact screen size and bay depth → Before You Mount Confirm Projector Placement Before Installing The ZK521ST-B uses a fixed short-throw lens — placement is not adjustable once the mount is installed. Before ordering a projector mount or running cable, confirm your screen width, ceiling height, and enclosure depth using the ESG Projector Fitment Tool. Short-throw projectors are unforgiving on mount position: a few inches in the wrong direction means the image misses the screen or doesn’t fill it. Measure twice, mount once. Use the Projector Fitment Tool → Complete the Bay Add an Enclosure — The Bundle Supplies the Overhead and the Light This bundle covers the launch monitor, projector, and impact protection. An enclosure and hitting mat complete the bay. The VTrack’s 31″ × 24″ hitting zone is compatible with the Eagle 12 and Albatross 13 standard enclosures. Eagle 12 Enclosure The most popular ESG enclosure — a 4:3 screen format well-suited to standard ceiling heights and typical bay widths. 12 ft Wide 8’2″ Tall 5 ft Deep 4:3 Screen View Eagle 12 → Albatross 13 Enclosure A wider 16:9 widescreen format for buyers who want the full panoramic course view that 4K resolution delivers. 13 ft Wide 8’2″ Tall 5 ft Deep 16:9 Widescreen View Albatross 13 → Need help choosing the right enclosure for your space?

4K UHD · Laser · Short Throw Bright Enough For Any Sim Bay, Sharp Enough For Every Shot The Optoma ZK521ST-B is a 5,000-lumen 4K UHD short-throw laser projector built for golf simulators that need to push light through a screen even when the room lights are on. True 4K resolution keeps fairway texture, ball flight, and on-screen data crisp. A 0.79:1 throw ratio handles tight ceilings and short hitting distances without compromising image size. 4K UHD Resolution 3840 × 2160 native 5,000 ANSI Lumens Lights-on brightness 0.79:1 Throw Ratio Fixed short throw 30K Hour Laser DuraCore, Eco mode Why The ZK521ST-B Built For Bright Rooms And Long Hours Brightness, color, and rated life are the three numbers that separate a simulator projector from a living-room model. The ZK521ST-B is engineered around all three, with 24/7 operation support and a sealed laser engine designed for commercial-grade reliability. 5,000 Lumens High output keeps the image vivid in bays with bright LED lighting, large windows, or open commercial space — no need to black out the room. True 4K UHD 3840 × 2160 native resolution holds course textures, simulator overlays, and tracer data sharp at screen sizes up to 300″. 0.79:1 Short Throw A fixed short-throw lens fills a 10ft wide screen from about 8 feet away, cutting shadows on the hitter and freeing up ceiling space. 30,000-Hour Laser DuraCore laser light source is rated up to 30,000 hours in Eco mode — over a decade of normal residential use with no lamp swaps. 8.4ms Input Lag Input lag drops to 8.4ms at 1080p/120Hz and 16.7ms at 4K/60Hz, keeping ball-strike response tight in fast simulator software. 24/7 Operation Rated for continuous 24/7 use, making the ZK521ST-B a fit for commercial sim bays, training studios, and entertainment venues. Optoma Smart Fit Smart Fit alignment in the Optoma Smart Control app uses a phone photo of the screen to auto-calculate geometry and four-corner correction — no ladder, no remote-button keystone hunt. Dedicated Golf Sim Mode Optoma's Golf Sim Mode tunes color, contrast, and response for simulator gameplay — brighter blue skies, deeper shadows, natural greens, and faster on-screen response. One-touch from the remote. Who Is It Best For? Premium residential simulator rooms with ambient light Commercial bays running long daily sessions Tight ceilings needing a short-throw fixed lens Bays already running 4K launch monitor software Builders prioritizing rated laser life over zoom range Installations where 24/7 reliability matters Short Throw & Setup Engineered For The Way Sim Rooms Are Actually Built Placement Flexibility The 0.79:1 fixed throw works in the sweet spot for most residential and commercial sim rooms — close enough to reduce shadows, far enough back to clear the hitter and tracking hardware.

Two-Piece Combo · Tracking + Display Overhead tracking and a 4K image in one order This combo pairs the ProTee VX overhead launch monitor with the Optoma ZK521ST-B 4K Laser Short Throw 5000-Lumen Projector. It covers the two decisions that set the ceiling on how a simulator bay actually plays — what reads the shot and what puts it on screen — and leaves the enclosure, screen, and mat open so the rest of the build can follow the room. Every ProTee VX combo in this lineup ships with the same launch monitor, the same perpetual ProTee Labs license, and the same included set of two ProTee swing cameras. The projector is the only variable, and the Optoma ZK521ST-B is the 5,000-lumen answer for builds that want the balanced default for a home bay running 4K simulator software. 01 ProTee VX Overhead Launch Monitor Ceiling-mounted, markerless, 24 data points, perpetual ProTee Labs license, two swing cameras included. $6,500 02 Optoma ZK521ST-B 4K Laser Short Throw 5000-Lumen Projector 4K UHD 3840 × 2160 · 5,000 ANSI lumens · 0.79:1 short throw. $2,699 Combo pricingBought separately the pair carries a $9,199 compare-at value.

Free UPS Ground Continental US — no shipping charges Two Swing Cameras Included Face-on and down-the-line, a $600 value No Software Subscription Perpetual ProTee Labs license included ESG-Backed Support Mounting, activation, and software setup Component 01 · Launch Monitor ProTee VX — overhead, markerless, floor clear ProTee VX mounts above the hitting zone and tracks club and ball with dual high-speed cameras and AI-powered analysis. Nothing sits on the floor, nothing needs a marker or a sticker, and handedness switches without moving the unit. Ceiling-Mounted Overhead Design Mounts overhead with nothing on the floor, which leaves the hitting zone completely clear and removes any device the club can strike. Markerless Club And Ball Tracking Dual high-speed cameras with AI-powered tracking read the club and ball directly. No marked balls, no club stickers, no consumables. 24 Measured And Calculated Data Points 8 measured club data points, 7 measured ball data points, and 9 calculated flight data points, plus AI-powered insights inside ProTee Labs. Under 0.3 Second Shot Feedback Ball flight appears on screen fast enough that the shot reads as continuous with the swing rather than as a delayed replay. Instant Handedness Switching Right- and left-handed play switches in seconds with no repositioning of the unit and no separate calibration routine. Perpetual ProTee Labs License ProTee Labs is included outright with no recurring software fees. Practice range, bag mapping, wedge matrix, dispersion stats, and dual-screen visualizers are all part of the license. Installation requirementProTee VX needs a 9 ft to 10 ft ceiling window for overhead mounting. Ceilings above 10 ft require an extender mount. Mounting hardware, wiring, and calibration steps are documented on the ProTee VX setup and support page. Included promotionEvery ProTee VX ordered from Elite Sim Golf includes a set of two ProTee swing cameras at no additional cost, a $600 value, while supplies last. Tripods and camera mounts are sold separately. View the full ProTee VX launch monitor page Component 02 · Included Projector · Short Throw 4K The 5,000-Lumen Anchor Of The Optoma Golf Sim Lineup The ZK521ST-B is the most commonly specified projector in ESG simulator builds, and it earns that position on balance rather than on any single number. 5,000 ANSI lumens, true 4K, vertical lens shift, and an 8.4ms low-latency mode at 1080p/120Hz land in one chassis at a price that still fits a home bay budget. 5,000 ANSI Lumens A meaningful brightness step over 4,100-lumen class projectors, which shows up most on wide 16:9 screens and in rooms that cannot be fully darkened. Vertical Lens Shift 104% To 125% Shifts the image vertically without geometric distortion, so a ceiling mount can be positioned for cable routing instead of being forced into one exact spot. 8.4ms Input Lag At 1080p/120Hz Low-latency mode keeps the on-screen ball reaction tight against the ProTee VX shot feedback, which reads as immediate rather than delayed. 24/7 Rated DuraCore Laser Built for continuous operation, which matters in a commercial bay or a heavily used home simulator running long sessions.

One ProTee VX overhead launch monitor with its ceiling mount hardware and perpetual ProTee Labs license, the included set of two ProTee swing cameras, and one Optoma ZK521ST-B 4K Laser Short Throw 5000-Lumen Projector with its remote, power cable, and documentation. Both items ship on a single order. How much does the combo save against buying separately? The ProTee VX is $6,500 on its own and the Optoma ZK521ST-B is $2,699, so the compare-at value of the pair is $9,199. The combo is $8,279, roughly 10% off. Why the Optoma ZK521ST-B instead of another projector? It is the right choice for most home simulator bays running 4K launch monitor software, which is why it is the most frequently specified projector in ESG builds. Every ProTee VX combo in this lineup uses the same launch monitor, the same perpetual ProTee Labs license, and the same two included swing cameras, so the projector is the only variable across the five. How do I confirm the projector will fit my room? Use the Elite Sim Golf projector fitment tool and throw calculator. Enter the screen size and room dimensions and it returns the mounting distance for this projector. Throw math done by hand from a marketed ratio produces misleading results. Does this combo include an enclosure, screen, or hitting mat? No. This is a two-piece combo covering tracking and display only. For a complete bay with an enclosure, impact screen, and hitting mat, use the SimKit bundle builder or one of the pre-built ProTee VX Premium 4K packages. Is a projector ceiling mount included? A projector mount is not part of this combo. Projector mounts, cable kits, and enclosure hardware are available separately, and the SimKit packages bundle them in. Can I add the VX Protector impact shield? Yes. The VX Protector is a one-piece thermoformed clear polycarbonate shield made specifically for the ProTee VX and is sold as a separate add-on. How does this combo ship? Free UPS Ground to the Continental US. The launch monitor and projector may arrive in separate boxes or on separate tracking numbers depending on warehouse routing. What warranty applies? Each component carries its own manufacturer warranty — ProTee covers the VX launch monitor and Optoma covers the projector. Warranty terms are not changed by buying the two together. What support comes with the combo? ESG-backed support covers mounting questions, ProTee Labs activation, projector alignment, and simulator software setup after the order arrives. The ProTee VX setup and support page documents the install steps. Are the two ProTee swing cameras included in this combo? Yes. Every ProTee VX shipped by Elite Sim Golf includes a set of two ProTee swing cameras at no additional cost, giving face-on and down-the-line video synced to every shot inside ProTee Labs. Tripods and camera mounts are sold separately. What ceiling height does the ProTee VX need? ProTee VX is designed for overhead mounting inside a 9 ft to 10 ft ceiling window. Ceilings taller than 10 ft need an extender mount to bring the unit into range. Full mounting detail is on the ProTee VX setup and support page. Does the ProTee VX require a subscription? No. The ProTee Labs license is perpetual and included with the launch monitor. There are no recurring software fees to keep using the unit. Is Elite Sim Golf an authorized ProTee reseller? Yes. Elite Sim Golf is an authorized ProTee reseller. The ProTee VX serial number and ProTee Labs activation code are emailed automatically when the order ships. What simulator software does the ProTee VX work with? ProTee VX runs with GSPro and TGC 2019, plus E6 Connect and Creative Golf 3D. ProTee Labs is included as the native practice and analysis companion. Do I need special golf balls or club stickers? No. Tracking is markerless. Standard golf balls work and no stickers or dots are applied to the club. Does it work for both right- and left-handed golfers? Yes. Handedness switches in seconds without moving the unit, which makes it practical for a household or a facility with mixed players. The ESG Advantage Why buy the combo instead of two separate orders Two components bought together on one order, from an authorized dealer, with one support relationship covering both. One Checkout, One Order A single order for tracking and display instead of two separate purchases to reconcile. Authorized Dealer Elite Sim Golf is an authorized ProTee reseller. Serial number and activation code arrive by email at ship time. Free UPS Ground Continental US shipping included on the combo. Support That Covers Both Mounting, alignment, activation, and simulator software questions handled in one place. ProTee VX handles the tracking. The Optoma ZK521ST-B handles the image. $8,279 covers both, against a $9,199 compare-at, with the enclosure and mat left open so the rest of the bay can follow the room.
