Australian field example — NZ rules and conditions may differ.
Why we chose this video
Rather than trusting factory settings, the team in New South Wales lays out a long paper strip, sprays coloured liquid across it and scans the pattern. Changing the settings shows how coverage, swath width and drift change. It’s the clearest explanation we’ve found of what a careful operator checks before spraying.
New Zealand context
Drift is regulated in New Zealand through product labels and regional council rules. (Northland Regional Council) A tested set-up helps an operator meet them.
Key takeaways
- A drone’s effective spray width varies with wind, height, speed and droplet size. (Scion, 2020)
- Ask whether the operator has pattern-tested their drone, and what swath width they use for your job.
- Finer droplets drift further. Product labels and council rules limit drift, so settings matter.
- Ask for the spray record after the job, including the settings used.
