How the calculator works
- Depth for camera and overhead units = 1 ft screen gap + 8–10 ft ball to screen + 4.5 ft behind the ball.
- Radar units behind the ball use their stated ball-flight and unit distances.
- Ceiling = golfer height + 45.5 in × sin 45° + 1.5 in mat + 6 in margin.
- Width: 10 ft one-handed, 12 ft shared left and right.
