Gusts
They push droplets off the field and carry them where they shouldn’t go.
For drones, ground rigs, backpack sprayers and more
A dry day isn’t always a spray day.
SprayClarity combines wind, gusts, Delta T, temperature inversion, rain and Kp with your application method, and tells you hour by hour whether you can spray, and why.

Without a drop of rain
Five things that ruin an application
Your weather app shows you the sky. To spray, you need all of this checked against your method, hour by hour.
Temperature inversion
A mist of fine droplets hangs in the air and travels far.
High Delta T
In heat and dry air, droplets evaporate before they land.
Rain in the next hours
It washes the product off before it works.
High Kp
Geomagnetic activity makes your drone’s GPS unstable.
How it works

Mapping drone
Flying to map, photograph or film?
With the Mapping drone method the question changes: it’s no longer when to spray, but when to fly with good light and steady GPS.
- Sun height: ideal light from 40°, no long shadows
- Partial clouds that make the light uneven
- Wind and gusts, with more margin than spraying
- Kp index for GPS and RTK

Reviews
What people who use it say
It helps me determine the best times for spraying. Being able to plan applications ahead of time makes my work much easier and more efficient. Definitely a very useful tool for anyone doing agricultural spraying.
A perfect app for me. Mainly because here on the farm I spray with several types of equipment and on several crops. With it I don’t need to send anyone to check the week’s conditions: I get the right information myself, quickly, in the palm of my hand.
Finally a complete app with an hour-by-hour forecast. It has already saved me an unnecessary trip to the field. The notification feature helps a lot, and saving fields makes everything more practical.
