Launch-monitor alignment: build a repeatable target line
Set up a launch monitor on a level, measured target line and record the exact mode, ball position and distances.
Good data begins with a repeatable physical setup. Measure from the reference points in the manual, put the device on the surface the maker specifies and align it to the intended target—not to a convenient wall that may not be square.
Make a setup card for the exact model
| Record | Why |
|---|---|
| Mode | Net, indoor and full-flight modes may use different requirements. |
| Device-to-ball | Measure from the point defined by the maker. |
| Ball-to-screen | Radar systems may need a stated amount of visible flight. |
| Level and height | A mat can raise the ball relative to a device on the floor. |
| Target line | The device, ball and intended target need the maker's alignment. |
Garmin's R10 manual places the device 1.8–2.4 m behind the tee indoors and the ball at least 2.4 m from the net. Rapsodo's current FAQ gives its own distances, level indicator and hitting-area guidance. These are product-specific examples, not interchangeable standards.
Check settings as well as hardware
Confirm handedness, environment, ball type, elevation and software mode where the maker uses them. Rapsodo says its club-data hitting zone varies with dexterity; Garmin tells users to enter the exact device-to-tee distance when prompted.
Troubleshoot from the layout
If readings appear wrong, do not move several things at once. Recheck level, target line, measured distances, ball position, mode and current firmware in that order, then use the maker's support process. Keep containment and swing clearance separate from data quality: a monitor reading a shot does not make the room safe.
