While we use the term “beacon” in this article because it is the most commonly referred to term, be careful not to confuse an avalanche beacon (ie transceiver) with a PLB, which is a personal locator beacon.  A personal locator beacon is specifically used to send a help signal to search and rescue teams. However, external search and rescue teams are too far in the vast majority of circumstances to actually rescue an avalanche victim. PLBs may still be useful for calling in emergency medical assistance or some other help AFTER the victim has been dug out.  An avalanche beacon (transceiver), on the other hand, is for locating device that skiers or people nearby can communicate with to hone in on the location of a buried avalanche beacon.  PLBs are an external call for help. Avalanche beacons are used amongst your own party.
