During calibration, which action verifies the travel speed?

• A. Mark out a 200 ft course to verify your speed.
• B. Find swath width.
• C. Multiply swath width by 200 ft.
• D. Collect gallons sprayed in the strip.

Answer: (A)

Verifying travel speed during calibration comes from measuring a known distance and timing how long it takes to cover it, because speed is distance over time. By marking out a precise 200-foot course and timing your passage, you obtain your actual travel speed. This ensures the sprayer’s speed used in calibration matches what you’re actually doing in the field, which is essential for calculating application rate accurately. The other actions don’t confirm speed: finding swath width tells you how wide the spray pattern covers, but not how fast you’re moving. Multiplying swath width by 200 feet would give an area of sprayed strip, not your speed. Collecting gallons sprayed in the strip measures the volume output, not travel speed.
