This combo pairs the Uneekor EYE MINI Launch Monitor with the Optoma ZK521ST-B, Optoma’s 5,000-lumen 4K laser short-throw golf projector. It covers tracking and display on one order, and leaves the enclosure, impact screen, and hitting mat open so the rest of the bay can follow the room.
Uneekor EYE MINI Launch Monitor
Ground-based, dual high-speed cameras, 19 data points, onboard display, 6–8 hr battery, PC or iPad play.
Optoma ZK521ST-B 4K Laser Short Throw 5000-Lumen Golf Simulator Projector

Bought separately, these components total $5,698 (EYE MINI $2,999 + Optoma ZK521ST-B $2,699). This combo is $5,098, a $600 savings on one order.

Uneekor EYE MINI — portable photometric with an onboard display
The EYE MINI is a ground-based, dual-camera launch monitor that sits in front of the hitting mat, opposite the golfer. Ball Optix and Club Optix cameras capture 19 ball and club data points across a 12″ × 8″ hitting zone and read any standard ball through Dimple Optix. An onboard display and a 6–8 hour internal battery let it move between the simulator bay and an outdoor range session.
Ground-Based, No Ceiling Mount
Sits on the floor in front of the mat, opposite the golfer. Nothing to hang, and it can be moved between bays.
Dual High-Speed Cameras
Ball Optix and Club Optix cameras work together to capture impact and early ball flight.
19 Ball And Club Data Points
5 club, 5 measured ball, and 9 calculated ball-flight data points — ball speed, spin, launch, club path, face angle, and more.
Dimple Optix — Any Ball
Reads the dimple pattern on standard golf balls. No marked or proprietary balls required.
Onboard Display + Battery
Shot data on the built-in screen after every swing, with 6–8 hours of use per charge.
PC And iPad Play
CAT6 Ethernet to a Windows PC for GSPro, E6 Connect, TGC 2019, and VIEW, or Wi-Fi to an iPad through VIEW AIR.
EYE MINI sits on the floor in front of the hitting mat, so the launch monitor has no ceiling-height requirement. Full simulator play on the projector runs from a Windows PC over CAT6 Ethernet or an iPad through VIEW AIR. Reflective club stickers are recommended for full club data.
Optoma ZK521ST-B — the 5,000-lumen anchor of the Optoma golf lineup
The ZK521ST-B is the most commonly specified projector in ESG simulator builds, and it earns that position on balance rather than 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, most visible 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 the ceiling mount can be placed for cable routing instead of one exact spot.
8.4ms Input Lag At 1080p/120Hz
Low-latency mode keeps on-screen ball flight tight against the launch monitor’s shot feedback.
24/7 Rated DuraCore Laser
Built for continuous operation in a heavily used home simulator or a commercial bay.

What exactly comes in this combo?
One Uneekor EYE MINI Launch Monitor and one Optoma ZK521ST-B 4K projector. Projector mounting hardware and HDMI/power cabling are sold separately.
How much does the combo save?
Bought separately, the EYE MINI ($2,999) and Optoma ZK521ST-B ($2,699) total $5,698. The combo is $5,098, a $600 savings.
How do I confirm the ZK521ST-B fits my room?
Use the Elite Sim Golf projector fitment tool and throw calculator. The ZK521ST-B’s 0.79:1 throw ratio and 104%–125% vertical lens shift set the mounting window, but the exact lens-to-screen distance depends on screen size and aspect ratio.
Where does the EYE MINI sit in the bay?
On the floor in front of the hitting mat, opposite the golfer. There is no ceiling mount, and the unit can be moved to an outdoor range or another bay between sessions.
Do I need club stickers?
Stickers are recommended for full club data. The included reflective stickers go near the toe of the clubface and improve club path, face angle, attack angle, and smash factor readings. Ball data works with any standard ball through Dimple Optix.
How does the EYE MINI connect to my PC or iPad?
A wired CAT6 Ethernet cable connects it to a Windows PC for GSPro, E6 Connect, TGC 2019, or Uneekor VIEW. For iPad practice, it pairs wirelessly with Uneekor VIEW AIR.
How is the EYE MINI different from the EYE MINI Lite?
The EYE MINI adds a built-in display, an internal 6–8 hour battery, iPad VIEW AIR support, and outdoor portability. The EYE MINI Lite drops those features for a lower price as a dedicated indoor launch monitor.
Are a projector mount and cables included?
No. Projector mounting hardware and HDMI/power cabling are sold separately. The ZK521ST-B weighs 6.6 lbs and supports 360° orientation.
What warranty applies?
Each component carries its own manufacturer warranty — Uneekor covers the EYE MINI, and Optoma covers the projector.
