The Ocean Signal SafeSea S100 Radar Search and Rescue Transponder or Radar SART is a critical component of maritime safety equipment, designed to enhance visibility and aid in search and rescue operations. With its advanced radar reflector technology, this beacon ensures your vessel is easily detectable even in adverse weather conditions and low visibility situations.

Whether navigating busy shipping lanes or sailing in remote waters, the Ocean Signal SafeSea S100 Radar SART is an essential addition to any vessel’s safety gear, ensuring swift and effective response in emergency situations.

The SeaSafe S100 SART is designed to assist in the rescue and recovery of liferafts and survival craft. When switched on, the SART remains in a standby mode until automatically activated by an X Band Radar sweep from any vessel in the vicinity.
