emergency beacons
Crisis signal devices
Emergency beacons are devices that transmit distress signals to alert rescue services when someone is in serious trouble.
They include personal locator beacons carried by hikers and sailors, emergency position-indicating radio beacons on boats and aircraft, and avalanche transceivers for skiers.
When activated, they broadcast location data to satellites or search teams: The capsized yacht's emergency beacon brought rescuers within hours.
