Description
An avalanche transceiver or avalanche beacon is a type of emergency locator beacon, a radio transceiver for the purpose of finding people buried under snow. They are widely carried by skiers, particularly cross-country skiers, for use in case a skier is buried by an avalanche.
Following an avalanche, if some members of the ski party are buried, the others may switch their transceivers from transmit into receive mode, allowing use as a radio direction finding device to search for signals coming from the lost skiers.
