DaisyBell® is an innovative avalanche control solution is a mobile system, easily transportable by helicopter (with 15 to 30 m sling) and is ideal for inaccessible or particularly troublesome avalanche areas, depending on the conditions encountered.
FLEXIBLE: « for optimized effectiveness »
- Possible to deal with a large number of slide paths with a single system.
- Choice of height of explosion position depending on the snowpack.
- Precise positioning of the impact, even on a steep slope (no duds or sliding of the explosive).
SAFE: « to control the risk »
- No handling of explosives or human intervention in the area to be made safe to position the explosion above the snowpack.
- Readily supplied (short and long term) consumables (oxygen & hydrogen) at low cost and with no significant constraints on storage.
- No risk of unexploded charges.
- Shots can be viewed on site and avalanche outcomes recorded.
PROFITABLE: « for rapid return on investment »
- Time saved before, during and after the operation.
- Training and approval requirements are minimal.
- Very low cost per shot.
- Only a single operator needed in the helicopter.
- Very rapid implementation: 5 seconds per firing, 10 seconds waiting time between shots.
