FAQs
What is a Personal Locator Beacon (PLB)?
A Personal Locator Beacon (PLB) is a portable device that transmits a distress signal to satellites, allowing search and rescue teams to locate you in an emergency situation when you are in a remote area without other means of communication.
When should I activate my PLB?
You should only activate your PLB when you are in a life-threatening situation and facing grave and imminent danger. It should not be used for minor emergencies or changes of plan.
How does a PLB work?
When activated, a PLB sends a distress signal on the 406 MHz frequency to the international Cospas-Sarsat satellite system. The satellites relay the signal to ground stations, which then notify the nearest rescue coordination center with your location and registration information.
Do I need to register my PLB?
Yes, it is essential to register your PLB with the appropriate national authority. Registration associates your device with your emergency contact details, which helps search and rescue teams respond more effectively.
How long does a PLB battery last?
Most PLB batteries have a lifespan of 5 to 10 years, depending on the model. It is crucial to replace the battery before it expires to ensure your PLB will function properly in an emergency.
What should I do after activating my PLB?
After activating your PLB, stay in the same location and wait for rescue. Do not turn off your PLB until instructed by rescue services, even if you no longer need assistance.
Can I use my PLB abroad?
Yes, you can use your PLB in most countries, as it operates on the global Cospas-Sarsat satellite system. However, it is advisable to check with the relevant authorities in the country you plan to visit, as some countries may have specific regulations regarding PLB usage.
