Doppler radar launch monitors rely on tracking the golf ball as it moves through the air. Air movement caused by fans, underfloor heating, or air conditioning can interfere with this process and lead to inaccurate or inconsistent readings.
Why Air Movement Matters
Doppler radar calculates shot data by tracking the ball’s speed and flight path. Strong or uneven air movement can:
Disrupt the ball’s early flight
Introduce noise into the radar signal
Reduce the accuracy of calculated metrics
This is most noticeable in indoor environments where ball flight is limited.
Fans
Using fans near the hitting area can:
Push or slow the ball during the first few feet of flight
Cause inconsistent carry and ball speed readings
Result in occasional missed shots
Even small fans positioned near the ball or launch monitor can affect results.
Underfloor Heating
Underfloor heating can create:
Warm air rising from the floor
Subtle air currents near the strike area
While not always obvious, this air movement can interfere with radar tracking, particularly for low-launch or short shots.
Air Conditioning
Air conditioning systems can:
Produce constant airflow across the hitting area
Create turbulence between the ball and launch monitor
Air vents positioned in front of or above the strike zone are most likely to cause issues.
Recommended Setup
To minimise air-related interference:
Turn off fans during practice sessions
Avoid positioning the launch monitor near air vents
Allow the room temperature to stabilise before use
Ensure the air is as still as possible around the ball and device
A calm, stable air environment helps ensure consistent readings.
Outdoor Use
Natural airflow outdoors generally has less impact due to longer ball flight. However, strong wind can still affect data consistency.
