DaisyBell® system is a groundbreaking technology that has transformed the field of avalanche control. Developed by the French company MND Group, this system offers a safer, more efficient, and cost-effective solution for triggering controlled avalanches.
Development of the DaisyBell® System
The DaisyBell® system was born out of a need for a more efficient and safer method of triggering controlled avalanches. Traditional methods often involved the use of explosives, which posed significant safety risks and regulatory challenges. MND Group, a global leader in mountain and safety infrastructure, took on the challenge of developing a better solution.
The result was the DaisyBell® system, a mobile avalanche control solution that could be transported by helicopter to the ideal position for triggering an avalanche. This system works by emitting precise, programmed blasts using mixtures of oxygen and hydrogen, moving snow and triggering avalanches in a controlled manner.
Benefits of the DaisyBell® System
The DaisyBell® system offers several key benefits that make it a superior solution for avalanche control:
- Safety and Precision: System is controlled by a single operator in the helicopter, ensuring complete safety without the need to handle explosive charges. A viewer shows the helicopter pilot the exact distance between the DaisyBell® and the snowpack in real time.
- Heli-Transportable: System is considered a non-explosive cargo transport operation by aviation authorities, making it easy to transport via helicopter.
- Autonomy: System has the autonomy for up to 70 blasts, making it a reliable solution for avalanche control operations.
- Reduced Regulatory Limitations: System reduces the limitations and contraindications related to the laws that regulate the storage, transportation, and use of explosives.
- Cost-Effective: System has no consumable elements apart from gas, resulting in reduced costs to use and maintain the system.
Role of the DaisyBell® System in Avalanche Control

The DaisyBell® System in Flight
The DaisyBell® system plays a crucial role in modern avalanche control operations. It is particularly effective in exceptional winter conditions, where it can cover several avalanche chutes depending on the actual snowfall reported. Its precision and safety make it an ideal solution for protecting winter sports enthusiasts, mountain travelers, and communities residing in avalanche-prone areas.
Furthermore, the DaisyBell® system is an integral part of helicopter avalanche control services offered by companies like Fair Lifts. These services provide state-of-the-art helicopters, highly trained pilots, and extensive North American coverage, ensuring that avalanche control operations are as effective, efficient, and safe as possible.
A Significant Advancement
The DaisyBell® system represents a significant advancement in the field of avalanche control. Its development by MND Group and its adoption by leading helicopter service providers like Fair Lifts demonstrate the potential of this technology to revolutionize avalanche control operations. As we continue to face the challenges of managing avalanche risks, the DaisyBell® system will undoubtedly play a crucial role in ensuring the safety and well-being of those venturing into avalanche-prone areas.
