Setup and Installation Experience
The Trackman iO Duo adapts to a variety of room widths. You can choose between three mounting positions based on your available space:
- Wide Setup (Position I) – Suitable for room widths between 11’6” and 14’. The two IO units are positioned 3’7” apart.
- Medium Setup (Position II) – Fits rooms with 10’4” to 11’6” widths, with 4’3” distance between the two units.
- Narrow Setup (Position III) – With a 4’11” distance between the tracking systems, this configuration is good for room widths between 9’6” and 10’4”.
This flexibility allows installation in most indoor spaces without sacrificing tracking accuracy. The sensors maintain alignment regardless of width when mounted correctly.
Tee Area & Environment Requirements
Each player needs a dedicated hitting zone, measuring 24″ x 16″. These zones must be surfaced with green or reflective turf, no smaller than 40″ x 40″. This is critical for accurate shot detection.
The ceiling should be at least 9’4” high. Lower ceilings could obstruct the camera’s field of view or interfere with the ball’s trajectory tracking.
Environmental lighting isn’t a big issue—infrared tracking handles most lighting conditions. Still, excessive glare or shadow should be avoided to ensure consistent readings.
Installation Complexity
Mounting the units is straightforward in theory, but precision matters. Both sensors attach to the ceiling using VESA-compatible mounts or optional poles. Spacing and angle must match the configuration guide exactly.
The system includes alignment software that detects positioning errors in real-time. If you opt for the Wing mounting bar, sensor calibration becomes faster and more precise. The Wing helps you avoid misalignment between sensors, especially in narrow rooms where space is tight.
You’ll also need a high-performance PC. Trackman recommends an NVIDIA RTX 4070Ti GPU or better. Without that, you may experience lag in shot data or slow rendering in simulator environments.
Installation can be done solo with the right tools, but if you misalign the sensors, your data could drift. That’s why we recommend you bring in professionals.
