MOB1 AIS and DSC MOB Retrieval System from Ocean SignalsOcean Signal
Ocean Signals MOB1
This is the newest and most innovative Man Overboard Recovery System on the market ... for the first time, AIS (Automatic Identification System) and DSC (Digital Select Call) emergency transmissions are possible from the one device.
The MOB1 takes up where the Kannad R10 leaves off, its smaller and more readily connects to a wide range of PFDs for automatic activation when the life jacket inflates, and it sends your alert to all vessels with AIS and / or DSC - which covers most vessels now days.
With DSC now mandatory for all new VHF and HF radios under the AYF Cat 1-3 regulations, the value of the DSC feature is rapidly increasing - with more and more boats out there able to receive your alert and GPS coordinates to come to your aid.
When out at sea, we know that the quickest rescue is from the boat you fell off or another vessel in the area ... the MOB1 from Ocean Signals is the must have item of safety equipment.
With a 7 year battery life, and the ability to turn it off after each use and reactivate, amortised over 7 years that's $60 per year and great insurance for anyone!
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.

Thankfully, I have not had to try it in real conditions, but I have performed the recommended tests and it works as planned. First, it will set off a DSC alarm on the VHF, which is great as it will wake up a sleeping crew. Second, it will provide an AIS position to home on, which will provide a great help to get bak to the MOB. On the whole a great innovation in safety.
