Sea Marshall® ‘SOS’ Man Over Board Systems
Personal Locator Beacon
So Small It Can Be Worn Inside a Lifejacket!
The system has two main components which interact with each other
to create the ‘Sea Marshall® Man Over Board System’
The Alert Unit is worn by each crew member. There is a miniature ‘SOS’ MOB Alerting
Unit (Personal Locator Beacon), robust, fully automatic miniature radio
transmitter designed to be discreetly worn around the neck or incorporated
into a lifejacket, immersion suit. In the event of a crew member falling
over board, within approximately 15 seconds, their Sea Marshall®
‘SOS’ Alerting Unit will automatically transmit a signal on 121.5 MHz,
the International SAR homing frequency.

The Receiver Unit is the Sea Marshall® ‘SOS’ Base Unit. The Base Unit can be one of two
options; it can be either a MOB alarm only, the Sea Marshall® Crewguard.
Or it can be the dedicated Man Over Board Alarm and Radio Direction Finder
called the Sea Marshall® SARfinder®. This raises the alarm
and gives the Direction of the MOB on its high visibility, fully waterproof
electroluminescent backlit display panel.
