PowderBee is your flying safety beacon for powderous adventures. PowderBee keeps your group safe by supporting the search procedure in an emergency. The system is straightforward and integrates in the common search procedure: you move to the last point of sighting and turn your beacons into search mode. If you are not close enough to immediately begin the fine search, PowderBee comes into play.

You point PowderBee in the direction of the avalanche cone and simply press the start button. PowderBee starts and follows the common search pattern. When PowderBee finds a signal it automatically lands. The landing point is in very close vicinity of the victim. You now continue with the fine search from the landing point. While PowderBee searches for the signal your group has the time to calm down and organize the rescue process.

The Current Prototype

Our current prototype demonstrates the functionality we want to achieve in the final product. It features our self-developed avalanche transceiver which is compatible to any beacon on the market. It is specifically designed to receive a signal in close vicinity of the buried person. It is shielded against the interference of the drone's electronic systems.

PowderBee keeps a steady ground distance with a special sensor to avoid avalanche debris. After activation the drone follows the standard search procedure: it flies meander over the avalanche cone until the reception of a signal. It is optimized for alpine conditions: high altitude, wind and cold.


During the development and with much appreciated feedback from the community PowderBee shapes up to be a cleverly devised product, made by wintersport-lovers for wintersport-lovers:

  • Acts as an additional person in the search at the low expanse of taking only 600 grams more with you
  • PowderBee knows the perfect search pattern and follows it without any error
  • Buys significant time by conducting the coarse search
  • Moves way faster over avalanche debris than a human ever could
  • Very flat form factor which fits in every backpack
  • Compatible to any avalanche beacon
  • Re-usability and testable: make yourself confident in integrating PowderBee in your emergency procedure
  • Designed to withstand low temperatures and it is not easily impressed by wind and weather
  • High visibility on rocky, snowy, cloudy or bluebirdy background
