406 MHz beacons
A 406 megahertz (MHz) beacon can send a distress signal via satellites to alert search and rescue authorities to your location. There are 3 types:
- Emergency Position Indicating Radio Beacons (EPIRBs) for vessels
- Emergency Locator Transmitters (ELTs) for aircraft
- Personal Locator Beacons (PLBs) for personal use
You must register your beacon and keep your registration up to date.
