Mobilarm Crewguard Base Unit

On detecting the signal, the Mobilarm Crewguard automatically sounds the alarm and displays a man overboard warning light. Proximity to the man overboard is indicated via a simple LED display. Additional Direction Finding equipment may be necessary to locate man overboard.
