Best Practices for Using a Personal Locator Beacon?

May 8, 2026

Quick Answer

Register your Personal Locator Beacon (PLB) with the relevant authorities, ensure it's fully charged or replace the battery annually, and understand the activation process to minimize false alarms.

Registering and Maintenance

Registering your PLB with the relevant authorities, such as the National Oceanic and Atmospheric Administration (NOAA) in the US, is crucial for timely response in case of an emergency. This ensures that rescue teams are notified and dispatched to your location with the least delay. In addition to registration, it’s essential to replace the battery annually or as recommended by the manufacturer, regardless of the battery’s condition, to ensure the device remains functional.

Activation and Use

To minimize false alarms and ensure a rapid response, understand the activation process of your PLB. Typically, this involves pulling a lanyard or pressing a button, usually located on the front or side of the device. Be aware that PLBs emit a distress signal that can be heard by satellites and relayed to rescue teams, so only activate the device in life-threatening emergencies. Familiarize yourself with the PLB’s operation and test it periodically to ensure you’re prepared in case of an emergency.

Emergency Response

In the event of an emergency, stay with your PLB and try to conserve energy. Stay visible if possible, and use any available means of signaling for help, such as whistling, waving, or using a mirror to reflect sunlight towards any potential rescuers. Stay calm and provide accurate information to rescue teams, including your location, the number of people in your party, and any relevant medical conditions.
