Marine Man Overboard Devices

Stay connected and safe with reliable Marine Man Overboard Devices (MOB Systems)

In a man-overboard situation, every second counts. Marine Man Overboard Devices from The Outdoor Warehouse help locate and recover crew members fast. Featuring AIS transmitters, MOB beacons, and personal recovery systems, these safety tools connect directly to your vessel’s navigation or rescue equipment.

Our selection includes top-rated AIS MOB beacons, automatic water-activated transmitters, and Bluetooth-connected smart recovery systems — essential for sailors, cruisers, and offshore professionals.

Understanding MOB Systems & Integration

Modern Man Overboard Systems integrate with multiple technologies, including AIS (Automatic Identification System), DSC (Digital Selective Calling), and satellite networks. When activated, they transmit position data to nearby vessels and rescue coordination centers for immediate response.

For offshore or commercial boats, we recommend dual-use beacons like the Ocean Signal MOB1 or ACR AISLink, which combine AIS and DSC for redundancy.

Every MOB device should be paired with a USCG-approved PFD and tested annually to confirm functionality.

Reminder

Attach your MOB beacon directly to your life jacket or harness loop, not your clothing. Test your device before every trip, and keep spare batteries on board for long voyages.

Frequently Asked Questions

What’s the difference between an MOB device and an EPIRB?
An MOB device transmits to nearby vessels using AIS or DSC for local recovery, while an EPIRB sends a distress signal via satellite for long-range rescue.
How do AIS MOB devices work?
AIS MOB devices automatically activate when submerged, broadcasting GPS coordinates to AIS-equipped vessels and chartplotters within range.
Do I need both an MOB and a PLB?
Yes, for maximum safety. MOB beacons alert nearby boats immediately, while PLBs ensure global rescue coordination via satellite.
