A water safety device includes a transmitter device adapted for operation with an alarm and search console. The transmitter device includes an alerting unit and an associated activation sensor. Activation of the alerting unit results in the transmission from the alerting unit to the alarm and search console of a tracking signal. The activation sensor may be any transducer or combination of transducers capable of sensing physical phenomenon generally concomitant a fall into water from a boat or ship. The alerting unit is adapted to immediately begin transmission of a predetermined signal for tracking of the life preserver and transmitter device by the alarm and search console following activation by the activation sensor. The alerting unit may be adapted to cause automated inflation of one or more inflatable bladders upon any indication that the wearer of the water safety device has fallen from the boat or ship.
