Room size: will the Voice Caddie Swing Caddie SC4 PRO fit?
The Voice Caddie Swing Caddie SC4 PRO sits on the floor behind the ball, looking down the target line. A radar unit behind the ball has to see the ball fly before it hits the screen, so depth is the critical dimension.
| Dimension | What to plan for | How it's worked out |
|---|---|---|
| Depth, screen to back wall | 15 ft minimum · 17 ft comfortable | 1 ft screen gap + 8 ft of ball flight + 5 ft unit distance + 1 ft behind the unit |
| Width, right-handed only | 10 ft minimum · 12 ft comfortable | Swing arc on both sides of the golfer |
| Width, left- and right-handed | 12 ft minimum | Centered hitting area so either stance fits |
Ceiling height for a full driver swing
| Golfer height | Estimated ceiling needed | Working |
|---|---|---|
| 5′6″ | 8′ 10″ | 66 in + 45.5 in × sin 45° + 1.5 in mat + 6 in margin |
| 5′10″ | 9′ 2″ | 70 in + 45.5 in × sin 45° + 1.5 in mat + 6 in margin |
| 6′2″ | 9′ 6″ | 74 in + 45.5 in × sin 45° + 1.5 in mat + 6 in margin |
| 6′5″ | 9′ 9″ | 77 in + 45.5 in × sin 45° + 1.5 in mat + 6 in margin |
FOREference calculationEstimated ceiling = golfer height + driver length × sin 45° + mat height + a safety margin. Steep, upright swings need more; test with a practice swing before you buy. Run your own numbers.
What it measures, and how
The listing shows 12 ball parameters and 1 club parameter. Spin is derived from club data rather than read from the ball, so spin-driven numbers such as carry on wedges and curve are estimates.
| Group | Parameters listed by the seller |
|---|---|
| Ball data (12) | Carry distance, Total distance, Ball speed, Smash factor, Apex, Launch angle, Launch direction, Spin rate, Spin axis, Side spin, Back spin, Dispersion |
| Club data (1) | Swing speed |
- Ball marking: Not required
- Club marking: Not required
Software, subscriptions and five-year cost
Software listed: MySwingCaddie app and Built-in 3D driving range. No third-party simulator platform is named in the listing.
| Cost item | Amount |
|---|---|
| Hardware (listed price) | $500 |
| Subscription | Not stated in the listing — check before buying |
FOREference calculationFive-year total = listed hardware price + 5 × the listed annual plan. Excludes tax, a PC, the screen and enclosure. Build your full five-year budget.
Building a simulator around it
Behind-the-ball radar is indifferent to handedness: left- and right-handed golfers hit from the same spot.
What else a full simulator needs
- An impact screen and enclosure (or a net for practice without course play) — see enclosures & screens
- A short-throw projector matched to your screen shape — see the throw calculator
- A hitting mat — see mats & turf
