Radar SART: A Radar Search and Rescue Transponder (SART) is a critical piece of equipment in maritime safety. It is used to aid in search and rescue operations by emitting a signal that can be detected by nearby radar systems. The SART transponder responds to radar signals by transmitting its own, allowing rescuers to locate distressed vessels or survivors. Regular testing of SART devices is vital to ensure their functionality when they are needed most. Regular maintenance includes battery checks, signal testing, and inspection for physical damage. By maintaining radar SART devices, vessels ensure they have a reliable means of being located in emergencies, improving overall safety at sea.
