It is now possible to precisely locate a man over board thanks to a smart bracelet paired with smartphones. Called Sea Tags, this solution benefits from beacon technology: A Bluetooth tag inside the bracelet continuously sends a signal to one or multiple smartphones with the Sea Tags app installed.
If the person goes too far away from their smartphone or is immersed, the signal is interrupted, which triggers an alert and records the GPS position. Text messages can then be sent automatically to pre-recorded mobile phones (a single phone can be paired with multiple tags).
In the meantime, the Sea Tags app displays the man overboard position, the boat’s real-time position and the path to follow to pick up the person.
One Sea Tags costs €79.
