Abstract
An alarm unit for a ski has a battery powered circuit which energizes an audible alarm in response to the output from a movement detector on the indication of absence of movement for a predetermined time. This allows a buried ski or a buried skier to be detected. A remotely controlled mode switch enables the unit to be switched to a theft mode in which the alarm is energized on detection of movement by the movement responsive unit.
