AISLink MOB Man overboard locator device
Overboard situations can be a little less hair-raising with the Automatic Identification System (AIS) Man Overboard Beacon (MOB). The AISLink features integrated Digital Selective Calling (DSC) and GPS technology, so you can quickly reach out for help when you need it most. 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. Plus, the DSC alarm on your vessel’s VHF radio can also be signaled to make first responders aware of what’s going on.

Seconds count in a man overboard situation. The AISLink MOB automatically activates upon inflation of the lifejacket, sending an initial alert within 15 seconds to all AIS receivers and plotters in the vicinity. Both positioning and MOB emergency messages are transmitted alerting vessels up to 5 miles away from your emergency situation.
Even in moderate seas, it is alarming how quickly a visual sighting of a man overboard can be lost. The AISLink MOB’s integrated GPS quickly pinpoints a precise location and transmits this as part of the AIS alert message to all local AIS equipped vessels. The AISLink MOB also has the ability to alert your crew to the emergency by activating the DSC alarm on your vessel’s VHF. All AIS receivers and AIS-enabled plotters within a 5-mile radius (dependent on conditions) are alerted, and an integrated high-intensity strobe light assists with accurate positioning even in low light conditions. Powerful lithium metal batteries provide 24+ hours of operational life, and the high-impact housing can withstand a drop to the water of 20m.
The video below details how to install the AISLink MOB. The video highlights use of the Oral Mounting Bracket to attach the MOB to the Oral Inflation Tube on an auto inflatable lifejacket with a separate bladder (additional installation instructions and installation scenarios are available in the AISLink MOB product manual which is accessed by clicking on the
Note that most modern AIS plotters and DSC VHF units comply with the standards for receiving MOB transmissions. However, it is recommended that you check with your equipment manufacturer to ensure compatibility. DSC functionality may vary — or be disabled entirely — according to the regulations of individual countries.
