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 meters, back to the vessel, plus providing a 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 the 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.

Compatibility: Most modern AIS plotters and DSC VHF comply with the standards required to receive MOB transmissions. It is, however, especially if you are using older equipment, recommended that you check compatibility with the equipment manufacturer. See the FAQs below for more information.

The MOB1 may be configured by the user to enter the vessels’ DSC MMSI number* by downloading the software at the link below. The vessel’s DSC number may be programmed multiple times.
