An Avalanche Beacon is a safety device used by outdoor enthusiasts, particularly skiers and snowboarders, to locate individuals buried under snow after an avalanche. It emits a continuous radio signal that can be picked up by other beacons, allowing rescuers to find the buried person quickly. These beacons operate in two modes: transmit and search. In transmit mode, the beacon sends out a signal, while in search mode, it receives signals from other beacons. Proper training in using an Avalanche Beacon is essential for effective rescue operations in avalanche-prone areas.
