Extra xFOB for your MOB+ system, 1 wireless xFOB.

MOB+ xFOB add more to your system

The xFOB is the heart of the MOB+ Wireless Man OverBoard System. xFOB is a small device, but packed with groundbreaking wireless technology.

Secure your whole family and connect up to 4 xFOBs at the same time!

The xFOB can be worn on your wrist, in your pocket, around your neck or clipped to your life jacket using either the xBAND™ or xTAG™ accessories. The waterproof xFOB™ has more than 300 hours of battery life, and is powered by an easy to change standard coin cell battery.

Universal Fit - Your choice

Intelligent Marine Wireless Technology

Universal Fit Design

The xFOB fits perfectly inside the xBAND and the xTAG. This unique design allows you to decide how you want to use the MOB+ Wireless Man OverBoard System.

We recognize that all boaters use their boats differently. For us this was a focal point in our design process of the product. You should choose your own boating environment. With this in mind we created the xFOB to be universal across all our accessories for the MOB+ system.

Genereral information about the system

As you step aboard your boat, press the xFOB to connect to the xHUB. A green light and an audio signal will confirm the connection and the engine can be started. Should a fall over board occur the engine will be shut down, caused by the xFOB being under water or more than 50 feet from the xHUB. 6 seconds after shut down passengers can restart the engine to save the person in the water. When leaving the boat press the xFOB once to disconnect.

Up to four xFOB’s can be connected to the xHUB at the same time, with one unit acting as the captain’s stop unit, and the additional three as alarm units for passengers.

Your personal safety guard

The corded kill switch is rarely used as it ties you to a very limited space onboard. With MOB+ Wireless Man OverBoard System you regain freedom – without losing safety.

The xFOB is your personal safety guard at sea. Being placed in the accompanying xBAND or xTAG, the xFOB unit does not inhibit any movement or motion. Should you fall into the water the engine(s) will stop in just one second.
