Having the right search and rescue device could be the difference between being saved within minutes or hours. An Automatic Identification System (AIS), Man Overboard Beacon (MOB) with an integrated Digital Selective Calling (DSC) transmitter is a bit of a mouthful, but is a great use of technology to save lives. With a MOB fitted to your life jacket, it’ll automatically set a man overboard alarm off by transmitting an alert to all AIS receivers and AIS enabled plotters in the vicinity. GPS will provide an accurate position and rescue can occur immediately, unlike EPIRBs which will need to be relayed from AMSA in Canberra, however an AIS will not alert the authorities. The MOB provides the best chance of rescue from the a vessel nearest to you. Typically this is from your own boat.

The integrated strobe light ensures maximum visibility in low light conditions.

The MOB1 communicates with the vessel you have been separated from and other vessels in the vicinity (up to 5 miles range dependent on conditions). To alert rescue authorities, an alternative product the RescueME PLB1 communicates directly via a dedicated search and rescue satellite network.

In an emergency RescueME MOB1 provides 2 methods of rapidly communicating your position, accurate to a few metres, back to the vessel, plus providing visual indication via its built in strobe light.

The best chance of rapid rescue if you fall overboard comes from your own vessel. Your crew needs to be immediately aware of the incident and keep track of your position whilst recovery is carried out. Even in the most moderate of seas it is alarming how quickly a visual sighting of a man overboard can be lost.

Once activated your MOB1 will transmit an alert to all AIS receivers and AIS enabled plotters in the vicinity. The integrated GPS ensures precise location is sent to your vessel and any others that may be assisting.

An additional feature of the MOB1, is its ability to activate the DSC alarm on your vessels VHF, alerting your crew to the situation.
