Emergency Position-Indicating Radio Beacons, or EPIRBs, are devices designed to alert search and rescue services in emergencies. When activated, they transmit a distress signal that includes the beacon's location, helping rescuers find individuals in distress, especially at sea or in remote areas. EPIRBs operate on specific frequencies and are often used by mariners, aviators, and outdoor enthusiasts. They are typically waterproof and buoyant, ensuring they function effectively in harsh conditions. The signals sent by EPIRBs are monitored by satellite systems, allowing for rapid response to emergencies.
