Avalanche beacons are electronic devices used by outdoor enthusiasts, such as skiers and snowboarders, to locate individuals buried under snow after an avalanche. These beacons emit a radio signal that can be picked up by other beacons, allowing rescuers to pinpoint the location of a buried person. They are essential safety equipment in avalanche-prone areas. When someone is caught in an avalanche, they can activate their beacon to transmit a signal. Other users nearby can switch their beacons to "search" mode, which helps them detect the signal and guide them to the victim's location. Proper training in using avalanche beacons is crucial for effective rescue efforts.
