Wireless audio communication solutions for Field Hockey Umpires.

As the authorities on fair play and rule observance, Field Hockey umpires can leave nothing to chance. To reduce the risk of errors as much as possible, it is essential that they react in a quick and concerted manner.

It is in this context that ADEUNIS RF has developed Vokkero , a wireless communication system that permits referees to stay in permanent contact, with excellent sound quality even in the most noisy environments.

The VOKKERO® Squadra system was also adopted by Field Hockey umpires during the National Women's Championship that took place in Washington. They were impressed by the contribution the VOKKERO® Squadra system made to the whole officiating team.
