How do PLBs and EPIRBs aid SAR missions?

• A. They provide weather forecasts to predict where searches should occur.
• B. They alert onshore authorities via social media.
• C. They transmit distress signals and location data to rescuers, enabling faster localization.
• D. They function as personal GPS devices for hikers.

Answer: (C)

PLBs and EPIRBs are emergency beacons whose purpose is to directly alert rescuers and provide location data when you’re in trouble. When activated, they send a distress signal on dedicated frequencies to the international search and rescue satellite system, which then relays that alert to the appropriate rescue authorities. Many modern beacons also transmit GPS coordinates, so responders immediately know your exact position, allowing them to pinpoint you quickly and begin a targeted search rather than combing a large area. They’re designed for distress situations and can be activated manually or automatically in some cases, and they’re registered to the user or vessel for identification. They don’t predict weather, they don’t notify via social media, and they aren’t simply personal GPS devices for hikers. This direct transmission of distress and precise location is what makes them so valuable in speeding up localization and rescue.
