ProTee VX Overhead Launch Monitor + Optoma ZK521ST-B 4K Projector Combo
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.

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.
ProTee 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.
Every 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.
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.

Mounting distance depends on screen size, ceiling height, and where the ProTee VX sits overhead. Run the numbers through the projector fitment tool and throw calculator before drilling. Throw math done by hand from a marketed ratio produces misleading results.
In the box
Two components, one order. The launch monitor and the projector may arrive in separate cartons or on separate tracking numbers depending on warehouse routing.

What exactly comes in this combo?
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.
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.
