Meet Kray Protection - the most efficient form of crop protection application
Order drone Order service


We created the most advanced technology for crop protection to be used at the industrial scale for almost all crop production farms. Kray Protection drone demonstrates outstanding performance of crop dusting while lowering farmers’ expenses. It prevents yield losses that are inevitable when using other crop protection methods.
One-tenth the cost

One-tenth the cost

Less fuel, less maintenance, less staff. The cost of application with our drone is much less than traditional aerial or ground application. This allows mid-size farmers to have a return on investments of around 600%.

Self-driving technology

Self-driving technology

Our drone flies in a fully automatic mode. Using advanced computer vision system, it adjusts the trajectory of its movement according to the actual terrain and avoids obstacles in its way.

Industrial level of productivity

Industrial level of productivity

Kray Protection operates at a maximum speed of 70 mph, enabling farmers to have up to 1200 acres of coverage a day. The productive time reaches up to 85%, with only 15% is required for tank refills and battery charges.

Spraying with 5D precision

Spraying with 5D precision

Spatial precision of fertilization, often called 3d, is as much important for preserving a field’s processability as adjusting the volume of pesticides and conducting spraying in a right time. We combined these parameters to increase fertilization precision.

Unmanned aerial sprayers will certainly be an indispensable tool in the local processing of crops, so we look forward to the serial production of Kray Protection. No doubt, this technology is the part of our future progress. As soon as we have started working with multispectral and hyperspectral technologies of crops photography and data analyzing, such drones like Kray Protection will allow us quickly detect problem areas of the field and adjust the coordinates to use the proper volume of chemicals where needed. As a result, it will have a positive impact on yields, and, consequently, profits.

There are currently no efficient industrial automated crop dusting systems despite modern machinery being too expensive for most businesses.The Kray Protection drone is an easy-to-use and affordable solution. We reduced size and energy consumption of spraying machines drastically and avoid expensive combustion. The operational costs of our drone can be reduced to less than $1 per acre.

We wanted to provide farmers with the greatest efficiency of spraying. With this in mind, we supplied the drone with an ultra-low volume spraying system, which saves pesticides and eliminates excessive water waste. At the same time, by using the number of advanced technologies, we enabled an almost non-stop operation cycle with outstanding precision.

Partnership projects

Switching to new technological solutions takes time, especially when it comes to such a complex field as agriculture. With this in mind, we offer industry players to start with our technology gradually, ordering one or two drones for conducting pilot projects and testing solutions, which can potentially become a stable practice for future activities.
