A drone sprays an acre in roughly seven minutes with a fraction of the water a knapsack operation needs. For a farmer, that changes the calendar, a whole field can be treated inside a weather window instead of over three days.
Where the savings come from
- Dramatically lower water volume per acre
- More uniform droplet coverage, so less chemical per acre
- No operator walking through a treated field
- Treatment completed inside a single weather window
For the service operator
Spraying is sold per acre. The maths that matters is acres per day, battery turnaround and travel between fields. A Medium Class certified pilot with a heavy platform covers considerably more ground per day than a Small Class rig, which is what turns spraying from a side activity into a business.
