Polo presents officiating challenges unlike any other sport — vast playing fields, fast-moving horses, and the need for instant umpire coordination across long distances. VOKKERO Varsity II and Varsity II PLUS deliver clear, real-time, hands-free communication between polo umpires without the need for a base station. Lightweight and reliable, these wireless systems give umpires the range and audio clarity to coordinate effectively, maintain match control, and make confident decisions from chukker to chukker — at club competitions, professional tournaments, and international events.
