Emergency Positioning Indicating Radio Beacons or EPIRBs are compact, buoyant and portable emergency devices specifically designed to transmit a radio distress signal to alert emergency authorities of a need for rescue. Once activated, an EPIRB will continuously transmit a specific radio signal to be detected by satellites.

Following satellite detection, the emergency position and specific location data is then relayed to related authorities to begin rescue operations.Several EPIRB models can be owner registered with a relevant rescue co-ordination authority. Following activation, an owner registered EPIRB will provide rescue operators with the owner's name and emergency contact details plus the type of vehicle/vessel needing rescue. EPIRB registration greatly improves rescue response times.
