...unlike other systems the Sea Marshall® Maritme Survivor Locating Device Systems continuously monitors your crew 24/7 and activates automatically when needed (there are no antennas to deploy on buttons that have to be pressed…it is fully automnatic which is essential if you are unconscious/in cold shock or in complete panic!…If you fell overboard how would the rest of your crew know? It could be minutes before somebody realised you were missing. The tests we have undertaken have shown a person can be out of sight in less than 50metres in broad daylight! Add a strong current of 2 to 3 knots current into the equation and the person in the water can be out to sea before you know it. 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 and can be tracked and quickly located in an emergency either by you or by the Coastguard or Lifeboat service.
