SART Overview

The SART helps search and rescue services to quickly locate a life raft in the event of a
rescue at sea. The SART can either be stowed in a life raft, or mounted next to
emergency exits and then carried to the life raft in an emergency.
During an emergency, simply switch the SART on. When a vessel or aircraft with
marine X-band Radar comes within 5 to 7 nautical miles of the life raft, the SART
generates a distinctive "distress" pattern on the Radar screen (See figure 1). The radar
signal guides the rescuers directly to the SART.
