Synchronized diving
Synchronized diving (synchro diving) is a sport in which two divers dive at the same time as a team from a three-meter springboard or a ten-meter platform. It is one type of diving which has belonged to the Olympic games since 2000 Sydney Olympics. The competition consists of five or six rounds depending on the events. Divers dive two basic dives during the first two rounds. Then they dive more complex freestyle dives from the third to the fifth round. The winners are determined according to total scores from judges. There are two types of judges. One is a technical judge who evaluates degree of completion of their dives.  Another is a synchro judge who evaluates the synchronization of two divers. (synchro)
