Sea Marshall Crewguard Receiver

The CG-121 Man Over Board Alarm monitors workers wearing Sea Marshall Man Over Board Alerting Units (Personal Locator Beacons) and raises the alarm when a signal is received from the Alerting Unit of person who has fallen over board. The Crewguard Man Over Board Alarm can be connected to an optional (External Antenna) and (Autodialler) to vastly Increase the operating range of the system and provide Man Over Board Alert cover for crews working over large remote and often unmanned areas such as Marinas, Harbours/Ports, Jetties, Fishfarms, Windfarms etc.
