The Search and Rescue Transponder or SART is a device that assists the location of a ship or a survival craft in distress if in case they have abandoned ship. The SART will respond only to a 9GHZ ( X-Band, 3cm ) Radar. It should be checked every month. Activate the SART and check in the 3cm Radar if you will see a dotted line which it would usually displayed when interrogated by the RADAR. But be sure that there are no ships or any other vessel around within the vicinity of more than 12 NM, because they may mistakenly think that you are in distress.
