Personal AIS Units
Man Overboard situations are scary scenarios we hope we never find ourselves in, thankfully with AIS Beacons (automatic identification system) and PLBs (personal locator beacons) Man Overboard locating and recovery has become a lot easier.
Personal AIS beacons when activated transmit a signal locally. This allows casualty's position to be displayed on chartplotters that are enabled with AIS, be it on your own boat or others within the vicinity, this includes lifeboats that approach the scene. This aids you or your crew in locating and recovering the MOB yourselves or with other boats in the area.
PLBs when activated only transmit via the 406mhz and 121.5mhz frequencies - communicating via satellite to the most local rescue coordination centre who are able to deploy search and rescue services.
