Sea Marshall MOB Systems

MAINSTAY is proud to be associated with SEA MARSHALL Marine Rescue Technologies.

As with all Mainstay products we provide full Service and Certification with Sea Marshall Products.

Sea Marshall® Man Overboard Systems give an immediate warning of a Man Overboard Event and the ability to very quickly track and locate the missing person either as a Self-Managed rescue or SAR agency assisted rescue. A simple and highly effective 2-part system, an alert (transmitter) and a base unit (direction finder receiver).  The alerts can be easily integrated into work life vests and is automatically activated after the MOB is in the water for 5 seconds.  The system provides an immediate alarm to the crew and the direction finder (DF) receiver provides precision direction to successfully managed a rescue. 

The Sea Marshall Rescue Systems follows the Maritime Survivor Locating Device (MSLD) specifications.
The system is comprised of two basic components, an alert (transmitter) and base units (receivers)

…unlike other systems the Sea Marshall® Man Overboard system continuoulsy monitors all your crew, 24/7…if a crewmember fell overboard, or drifted our of sight on a dive they could be unconscious…it could be night time, they might be out of sight…how would you know…how would you find them…??? A Sea Marshall® Maritime Survivor Locating Device gives you peace of mind to know that your crew are safely covered. For the time it took you to read this, a Sea Marshall® Man Overboard/Lost Diver Locating system/Lone worker could have potentially saved your life.
