ABSTRACT:
A water alarm device for releaseable attachment to a user in a body of water includes a buoyant alarm unit having a water sensor. The water sensor is configured to sense if a sensing portion of the alarm unit is in contact with water. A release unit is configured to releasably attach the alarm unit to the user. A timer is in communication with the water sensor and is configured to determine a duration of water contact with the sensing portion of the alarm unit. The release unit is configured to release the alarm unit from the user when the duration of water contact is greater than a predetermined time, and the alarm unit is configured to travel to a surface of the body of water and activate an alarm when the alarm unit is released from the user.
