About AIS Search and Rescue Transmitters AIS Search and Rescue Transmitters (AIS-SART, or SART) are self-contained devices that transmit emergency position reports when activated. SART transmissions are different than standard AIS transmissions, so they appear differently on the chartplotter. Instead of tracking a SART transmission for collision avoidance, you track a SART transmission to locate and assist a vessel.
Navigating to a SART Transmission When you receive a SART transmission, a distress signal alarm appears. AIS-SART Targeting Symbols Select Review > Go To to begin navigation to the SART transmision. Enabling AIS-SART Transmission Test Alerts In order to avoid a large number of test alerts and symbols in crowded areas such as marinas, AIS-SART test alerts ignored by default. To test an AIS SART device, you must enable the chartplotter to receive test alerts.
