The worlds smallest personal locating AIS Man OverBoard device with integrated DSC.
Ocean Signal / MOB1
Introducing the world’s smallest AIS MOB device with integrated DSC – the rescueME MOB1 from Ocean Signal. The MOB1 is compatible with even the most compact inflatable life-jackets*.
The MOB1 is intended to be installed within the life-jacket* and will activate automatically on inflation, sending the first alert within 15 seconds. The MOB1 is waterpoof to 10 metres.
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.
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.

What DSC functions are allowed in my country?
The DSC functionality of the MOB1 is limited by regulations in each country. The list below indicates which functions you may expect.
AIS only: Canada, France, Denmark, Latvia
AIS + DSC Individual Distress Relay call plus group call sent after 30minutes: USA
AIS + DSC Individual Distress Relay call only: Germany, Netherlands, Spain, United Kingdom
AIS + DSC Individual Distress Relay, All Ships Distress Alert (manual initiation only): All other European countries
AIS + DSC Individual Distress Relay, All Ships Distress Alert, sent once on MOB1 activation and on manual initiation: Rest of the World.
How to programme DSC MMSI number into the MOB1
A video showing the programming sequence for the MOB1 can be found at this link.. Remember to set the display brightness to full before starting the sequence.
Note that the test key is being pressed directly and then the rubber adaptor fitted when the MOB is ready to programme.
Why does the displayed MMSI not change when I enter my DSC MMSI number?
All AIS and DSC MOBs are pre programmed at the time of manufacture with the self identification MMSI number. In the case of the rescueME MOB1, or the M100, this number will always start 97260—-. The 972 identities the device as an MOB device and the 60 identifies the device as manufactured by Ocean Signal.
It is not possible for the user to change this number, which is a requirement of the relevant approval standards.
The DSC MMSI number programmed in by the user is the number the MOB1 will send the distress calls to. Compatible radios will still show the ‘from’ MMSI number as the 972 number printed on the rear of the MOB1. Likewise the target displayed on an AIS plotter will also show with the target address as the 972 number.
What test modes does the MOB1 have?
There are three test modes on the MOB1; Functional, DSC and AIS/GPS.
The Functional test should be carried out once a month and will display the length of time the battery has been used for. It will also apply a load to the battery to test that the battery is not faulty or has been discharged. It carries out other functional tests on the electronic circuitry. It does not test the GPS or make test transmissions.
The DSC test should be carried out no more than two times a year. This test sends a single DSC transmission to the MMSI programmed into the MOB1, which will be displayed on the vessels DSC radio. It does not send a Distress or Distres Relay call and the call does not contain the position.
The AIS test should be carried out no more than three times a year. This test activates the GPS receiver and after the position is determined it makes an AIS transmission, which will display on a suitable AIS receiver or chartplotter. The received AIS message will show the position determined by the MOB1 GPS receiver. There is also a transmission of the AIS text message containing the words “MOB TEST”. Note that this test must be done with the MOB1 in full view of the sky. Without a valid position, the MOB1 will not transmit any AIS messages.
The limitation on the number of tests a year is to ensure that the battery will still have its full operational life at the expiry date of the battery.
What is the black cord supplied for?
The provided length of cord is supplied as a safeguard against accidental loss. The cord (lanyard) should be used to tether the MOB1 to a fixed point on the lifejacket that will not inhibit inflation or detach/untie if the MOB1 is accidentally removed from its bracket. The MOB1 fixing point for the cord is located on the top of the unit.
