Square Golf Home Edition — Camera-Based Tracking at $699
The Square Golf Home Edition sits beside the ball and uses two high-speed cameras with an eight-sensor infrared array to measure ball and club data in real time. No radar depth is required, and the unit works in a room as tight as 10’×10’.
Two-Camera Photometric
2 high-speed cameras + 8 infrared sensors capture ball and club at impact for photometric-grade accuracy.
13 Ball & Club Metrics
Ball speed, launch angle, spin, apex, carry, total, plus club path, face angle, dynamic loft, and angle of attack.
Left & Right Handed
Flip handedness in the app — no physical repositioning required for switching golfers.
Free GSPro & E6 Connect
Zero connector fee. Runs on iOS, Android, and Windows. 1,000 credits (~55 rounds) included at purchase.
Floor-based, no ceiling install. The Square Home Edition sits on a small stand or a level surface at ball height. There is no overhead rail or ceiling mount — ideal for basements, spare rooms, or garages with lower ceilings.
What You Need to Add to Play
This SimKit includes everything for the physical bay. To run the simulation, add either an iPad (or iPhone) or a golf sim PC. The free Square Golf app runs on iOS, Android, and Windows with 12 built-in courses. GSPro and E6 Connect are optional Windows-only add-ons.
Optoma ZK521ST-B — 4K UHD Laser Short-Throw
The Optoma ZK521ST-B is a native 4K UHD laser short-throw projector — the brightest projector in the Square Home Edition SimKit lineup. 5,000 ANSI lumens, HDR10, a 0.79 short-throw ratio, and a solid-state laser light engine rated for up to 30,000 hours put it in the same picture-quality tier as the marquee 4K projectors used in professional sim bays. Golf-tuned color modes and the built-in simulator setup wizard get the image dialed in for GSPro, E6 Connect, and TGC 2019 without a Saturday of menu tuning.
4K UHD (3840×2160)
Native 4K resolution renders course textures, greens, and pin flags with a level of detail 1080p projectors cannot match.
5,000 ANSI Lumens
Brightest projector in the Square Home Edition SimKit lineup — holds contrast against room ambient light and delivers a sharp, saturated image on the impact screen.
Laser Light Source — 30K Hours
Solid-state laser engine rated for up to 30,000 hours of operation. No lamp to buy or replace over the life of the sim bay.
0.79 Short Throw + Sim Wizard
0.79 throw ratio mounts close to the screen on the BenQ CM00G3 ceiling mount — clear of the swing path. Golf-tuned color modes and the built-in simulator setup wizard tune the image for GSPro, E6 Connect, and TGC 2019 in minutes.
Throw distance and ceiling clearance depend on the chosen enclosure and mounting height. Confirm fitment for your room using the Projector Fitment Tool before install.
Birdie 10, Eagle 12, or Albatross 13S
Every enclosure uses a powder-coated steel frame, triple-layer impact screen, velvet-lined walls, and tool-free snap-together assembly. Pick the width and screen ratio that best fits the room — the landing mat is included with each.
Birdie 10 — 10’ W × 8’ H × 5’ D
Fits rooms where width is limited — a single-car garage, a basement lane, or a tighter dedicated sim room. 4:3 screen delivers a full sim view. Include the 6’×12’ landing mat.
Eagle 12 — 12’ W × 9’ H × 5’ D
The most popular size — fits most garages, basements, and dedicated sim rooms. 16:9 widescreen ratio matches the projector natively. Includes the 6’×12’ landing mat.
Albatross 13S — 13’ W × 10’ H × 5’ D
Widest enclosure with a 16:9 screen — for larger dedicated sim rooms or basements. Includes the larger 6’×15’ landing mat for a wider hitting/putting area.
Room fit depends on both enclosure size and mount clearance. Use the Projector Fitment Tool to confirm ceiling height and throw distance for the ZK521ST-B in the chosen enclosure.
Big Moss 4’ × 5’ True Launch with Built-In Pure Flight Strip
The Big Moss 4’ × 5’ True Launch is a low-profile, dual-stance mat with the Pure Flight hitting strip built into a 10’’ × 20’’ replaceable insert on the left-hand side. Pure Flight is a real-turf feel strip with a nylon base that returns realistic feedback on strikes and holds a tee for full club selection.
4’ × 5’ Dual-Stance
Big enough for left- and right-handed swings with room to plant the trail foot. Landing mat sits in front for a full hitting area.
Pure Flight Insert Strip
Real-turf feel with a nylon base. Replaceable when the hitting strip wears — the mat body stays.
Ball + Tee Compatible
Pure Flight holds a rubber tee for driver and long clubs. Ball-to-turf strikes feel closer to real grass than a foam mat.
Long-Term Value
When the hitting strip wears from heavy use, replace just the Pure Flight insert instead of the whole mat.
Square Home Edition 4K SimKit — ZK521ST-B + Big Moss PureFlight Bay
Installed in a home bay: The Square Home Edition sits floor-mounted beside the ball, the ZK521ST-B ceiling-mounted for a clean image, and the Big Moss 4’ × 5’ True Launch with the Pure Flight strip inside the enclosure. Note the Eagle 12 is pictured; the same install pattern applies to the Birdie 10 and Albatross 13S.
Eagle 12 pictured. Putting green not included in the standard SimKit. Landing mat size varies by enclosure: 6’ × 12’ for Birdie 10 / Eagle 12, 6’ × 15’ for Albatross 13S.
Projector Install Kit + Landing Mat
Every SimKit includes the standard install kit and a landing mat matched to the enclosure size. No separate accessory order needed to complete the bay.
BenQ CM00G3 Projector Mount
Universal ceiling mount rated for the Optoma ZK521ST-B and every projector in the ESG short-throw lineup.
25ft HDMI + 25ft Power Cable
Long-run cables sized for standard ceiling projector installs above the enclosure.
Landing Mat Included
6’ × 12’ landing mat with Birdie 10 or Eagle 12; 6’ × 15’ landing mat with Albatross 13S.
