Personal Locator Beacon
Overview
A personal locator beacon (PLB) is an emergency communication device that transmits a distress signal via satellite to alert rescue authorities in life-threatening situations.
Key points
- Uses dedicated emergency frequencies for global coverage.
- Activated only in real emergencies due to legal implications.
- Requires registration with national authorities.
- Operates independently of cellular networks.
Details
PLBs are essential safety devices for hikers traveling through remote or hazardous terrain. When activated, they transmit a GPS-enhanced distress message to rescue coordination centers. Unlike communication devices that allow two-way messaging, PLBs provide one-way emergency signaling only. Their reliability and global reach make them a critical last-resort tool for backcountry emergencies.
