Petty Officer 3rd Class Benjamin Mullis, a coxswain from Coast Guard Station Mayport, demonstrates how to use a personal locator beacon (PLB) in Mayport, Florida, Sep. 30, 2020. Boaters should have an emergency position-indicating radio beacon (EPIRB) or a personal locator beacon (PLB) on-board to send a distress signal on the 406 MHz distress frequency via satellite and earth stations to the nearest Rescue Coordination Center, which then notifies local Search and Rescue assets.
