Advanced Automatic Identification System (AIS) technology comes to the rescue with this compact and affordable man overboard beacon with integrated Digital Selective Calling (DSC) and GPS. Unlike a personal locator beacon, which signals orbiting search and rescue satellites, AISLink sends an alert message within seconds to all local vessels with an AIS receiver and/or AIS-enabled plotter and the DSC alarm on your vessel’s VHF can also be signaled.
