SARTs (Search and Rescue Transponder) are primarily designed to be used in lifeboats or liferafts, but can also be used on board a vessel or even in the water. SARTs operate in the 9 GHz marine radar band, and when interrogated by a searching ship's radar, it responds with a signal which is displayed as a series of dots on a radar screen. The range achievable from a SART is directly proportional to its height above the water.
