S100 Search and Rescue Transponder (SART)

A dedicated radar transponder, the Ocean Signal SafeSea S100 Search and Rescue Transponder (SART) complies with IMO SOLAS regulations.

The S100 Search and Rescue Transponder (SART) has been designed in order to help with the rescue and recovery of liferafts and survival craft. When the S100 Search and Rescue Transponder (SART) is turned on, the unit remains in standby mode until it is automatically activated by an X Band Radar sweep from any vessel in the vicinity. The S100 Search and Rescue Transponder (SART) then sends a series of pulses, which will be displayed on the ship's radar as a line of dots, giving them a bearing towards the survival craft.

The S100 Search and Rescue Transponder (SART) shares the same controls as the SafeSea E100 EPIRB, which help make its operation easy for unskilled operators.
