"I used the Vokkero Squadra System during two events, in total in four matches, three times as a first Referee, one time as a second. Each time four persons were equipped with the System: the two Referees, the Scorer and the Referee Delegate.

The System has very positive effects on the quality of the performance of the Refereeing Corps. In addition to the hand signals we have now the possibility of spoken communication which improves the information exchange among the persons. The first referee who was before „alone“ on the other side of the net is much more involved. The Refereeing Corps is one group. The possibility to encourage each other is a big benefit: “Very good call”, “Come on, no problem”, etc.

Some decisions can be made quicker. In unclear situations the second Referee does not have to walk to the first, they simply talk. More Focus on the game is possible. The Scorer can give useful information concerning the team line-ups before and during the match, especially also in the intervals between the sets.

When using the Vokkero® SquadraSystem the communication of the request and the result are now easy and clear. Furthermore, the position of the technique is no more important".

Philippe Schürmann, International Referee Volleyball (Liechtenstein)
