S4 Rescue SART

A Search And Rescue Transponder (SART) is a Radar based emergency transmitter that is designed to be stored in a liferaft or as a carry on device in the event that it is necessary to abandon ship. When it detects an incoming X-band radar pulse from another vessel or aircraft it automatically transmits a response signal, which appears on the vessel’s radar display as a series of 12 dots pointing to your location. SARTs are supplied with a mounting bracket and must be manually activated once inside the liferaft. As a Radar SART is designed to only transmit when it detects an incoming radar pulse this dramatically increases the battery life, enabling them to operate continuously for typically over 96hrs.
