Avalanche Transceiver Overview
:
If you are buried by an avalanche, wearing a transceiver can help people find you. However, it will not prevent you from being buried, it will not prevent you from being killed by trauma, and it will not prevent you from suffocating while buried. Of course, if you are killed by an avalanche, a beacon will make it easier for rescuers to recover your body.
Avalanche transceivers (aka "beacons") can transmit and receive signals—hence the name trans-ceiver. In normal operation, your transceiver is set to transmit a signal. If somebody gets buried by an avalanche, other people switch their transceivers to receive mode and then search for the transmitting beacon. (Everyone who was not buried must switch to receive mode or the rescuers may inadvertently search for someone who is still transmitting on the surface.)
All modern avalanche transceivers display an estimate of the distance to the victim (in meters) and a directional indicator that points to the transmitting beacon. Transceivers with only one antenna cannot display a directional indicator and should have been retired many years ago.
With practice, and avalanche transceivers do require frequent practice, your transceiver will get you within a meter or two of the victim. However, that's only part of the avalanche rescue process, you'll also need to locate them with a probe and unbury them using a shovel. And you'll need to consider medical care and transportatio
