Search and Rescue Transponders (SARTs) are essential for emergency situations, providing the means to locate a distressed vessel or person at sea. Regular testing and maintenance ensure that the device is fully functional and ready to transmit an emergency signal when needed. Service includes testing the battery, verifying the signal transmission, and checking the overall condition of the unit. Properly maintained SARTs improve the likelihood of timely rescue, contributing to safer operations and compliance with SOLAS and GMDSS regulations. Routine maintenance helps minimize the risk of failure in emergency situations.
