How can I be sure that the engine(s) will stop if I fall over board with the MOB+?

WiMEA® Protocol is based on an active data transfer between the connected xFOB unit and xHUB. This means that no matter what happens, if the xFOB unit is in the water or far enough away from the xHUB (normally more than 50 feet/15 meters) the wireless signal will be broken and the xHUB will activate MOB mode which stops the engine(s).
