Many suports organizations have employed some measurements such as whistle cover to prevent droplet infection. Many circles of Tokyo Mini Volley Association use e-whisle as well.
e-Whistle has advantages such as splash-free, while it has disadvantages such as taking one hand, and needs for taking care of louder sound (do not use it near players’ ears).
MV Abiko basically uses e-whistle for referees of games. For your reference, we made a video that shows how we use e-whistles. Hoping this may some help.
On June 5th, we will have Kanto Festival. e-Whistle will be used in the games. From this event, videos will not been shown on YouTube. But the games must be fun and excited!
Under Covid-19 pandemic, we would keep enjoying minivolley, hopefully with you!
