Two high pitch frequencies for loudness close to the whistle and a lower pitch for distance all sound simultaneously. Recommended for Referee's especially in big stadiumsor anywhere that real power is required.

两个高的音调频率接近的哨音和一个较低的间距的距离所有声音同时响。推荐给有权威和影响力的裁判在体现真正的权威性时使用，声音特高特尖，关键是特容易吹，爆力特强。

最后这款CYCLONE 888美观，设计好看，颜色鲜艳，如汽车中保时捷，配上我们的腕带就完美的选择。
