Volleyball Signals Behind Back. For beach doubles they signify blocking schemes. The setter can hide her hand signal behind a players back so the opposing teams blockers can t see what she is calling.

When you see a player flash a number behind their back they are communicating with their teammate on what their block and defensive play will be. Hand signals are used by beach volleyball players to indicate to their playing partner the defensive they intend to adopt. Which brings me back to my previous point if the attack is fine and legal then play would continue as planned until the point is won.
Block cross closed fist.
Two fingers indicate zone 2 or right front. If the setter flashes one finger behind her back the serve delivers the ball to zone 1 or right back. Hand signals are used by beach volleyball players to indicate to their playing partner the defensive they intend to adopt. In noisy gyms its impossible for the setter to talk to her hitters that may be in the back row or on the opposite side of the court.
