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.
