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 ZK431ST-B — compact 4K for rooms where mount depth runs out
The ZK431ST-B is the tightest-throw projector in the Optoma 4K golf lineup. A fixed 0.496:1 ultra-short throw ratio puts a full-width simulator image on screen from close range, which makes it the right answer in bays where a conventional short-throw mount would sit too far back.
4,100 ANSI Lumens
Enough output to hold a bright, readable image on a 4:3 or 16:9 impact screen with some ambient light from a garage door or basement window.
Fixed 0.496:1 Ultra-Short Throw
Projects a full simulator image from roughly 1.3 ft to 10.8 ft, keeping the projector body clear of the golfer and the ball flight path.
True 4K UHD Detail
Native 3840 × 2160 resolution renders turf texture, yardage overlays, and shot data without the softness of an upscaled 1080p panel.
Compact DuraCore Laser
A laser light source with 300,000:1 dynamic contrast in a chassis up to 34% smaller than previous Optoma 4K models.

Mounting distance depends on screen size, aspect ratio, and ceiling height. Run the numbers through the projector fitment tool and throw calculator before drilling. At 6.4 lbs with 360° and portrait orientation support, the compact ZK431ST-B suits low-clearance ceiling installs; a projector mount is sold separately.

What exactly comes in this combo?
One Uneekor EYE MINI Launch Monitor and one Optoma ZK431ST-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 ZK431ST-B ($1,799) total $4,798. The combo is $4,548, a $250 savings.
How do I confirm the ZK431ST-B fits my room?
Use the Elite Sim Golf projector fitment tool and throw calculator. The ZK431ST-B uses a fixed 0.496:1 ultra-short-throw lens with a 114% native offset and no zoom, so the mount position is set by 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 ZK431ST-B weighs 6.4 lbs and supports 360° and portrait orientation.
What warranty applies?
Each component carries its own manufacturer warranty — Uneekor covers the EYE MINI, and Optoma covers the projector.
