While in many areas we are going big, in others small is better. Digital Yacht has teamed up with SIMY to create what they say is the world’s smallest AIS MOB Beacon. The AIS MOB100 Beacon incorporates a 72 channel GPS and AIS SART transmitter. When activated, it sends the MOB casualty’s current location as an AIS transmission which can be detected by any vessel equipped with an AIS transponder or even a simple AIS receiver. Optional devices like Digital Yacht’s AIS LifeGuard can also automatically sound an audio alarm to alert the crew of the emergency MOB situation. The MOB100 measures 115 x 40 x 22mm and weights 95g.
