The Search and Rescue Transponder (SART) is an essential device used for locating distressed vessels or personnel at sea. Regular maintenance ensures that SART units are fully functional in case of an emergency. Service tasks include inspecting the transponder for physical damage, checking its battery life, and verifying the transmission signal. SART maintenance ensures that the device will activate properly during distress situations, allowing rescuers to pinpoint the location of the vessel or individual in trouble. Regular servicing is crucial for maintaining the safety of both crew and passengers, and meeting international maritime safety requirements.
