Can two beacons interfere with each other during a rescue?

Interference and Distance Readings

When two beacons are within a certain distance of each other, typically around 30-40 meters, they can cause mutual interference. This can lead to incorrect distance readings on the beacons, making it difficult for rescuers to accurately locate the buried person. In an ideal situation, the distance reading on the beacons should be around 5-10 meters, indicating that the rescuer is close to the buried person.

Techniques for Minimizing Interference

Rescuers can minimize interference by having one person act as a “reference” and keeping a safe distance from the other beacons. This reference person can use their beacon to provide a baseline reading, while the other rescuers adjust their positions to get a accurate reading. Additionally, rescuers can use the “pinpoint” mode on their beacons to reduce the transmission range and minimize interference.

Best Practices for Avalanche Rescue

In the event of an avalanche burial, every minute counts. Rescuers should always follow established protocols and best practices for avalanche rescue, including using specialized equipment such as avalanche probes and shovels. They should also make sure to communicate clearly and stay calm to ensure a safe and effective rescue. In situations where beacons are being used, rescuers should take steps to minimize interference and get an accurate reading to locate the buried person as quickly as possible.
