Room size: will the Voice Caddie Swing Caddie SC300i fit?
The Voice Caddie Swing Caddie SC300i 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.
