Emergency Position Indicating Radio Beacons, or EPIRBs, are safety devices used primarily in maritime and aviation settings. They transmit distress signals to alert search and rescue services when activated. These beacons operate on specific frequencies, allowing them to communicate with satellites and ground stations, providing precise location information. EPIRBs are designed to be waterproof and buoyant, ensuring they remain functional in emergency situations. They can be manually activated or automatically triggered when submerged in water. By using EPIRBs, individuals can significantly increase their chances of being located and rescued in emergencies at sea or in remote areas.
