Types
The type of a beacon is determined by the environment for which it was designed to be used:
- EPIRBs (Emergency Position Indicating Radio Beacons) signal maritime distress,
- ELTs (Emergency Locator Transmitters) signal aircraft distress
- PLBs (Personal Locator Beacons) are for personal use and are intended to indicate a person in distress who is away from normal emergency services (i.e., 9-1-1)
Each type is sub-classified:

Senile fudge and solemn:

These dry leaves of his autumn.”
