This electronic whistle is great for refereeing various sports and/or fitness activities. They are very loud and cut through field noise easily. Recommended!
Super easy to use, you just hit a button and it lets go of a very audible whistle sound. There are three different types of whistles to choose from! Very easy to hold and the battery lasts for quite a while of use before having to change it.
I coach high school football and use this thing at every practice. I love the ability to give verbal instruction in conjunction with the whistle sound

This sounds like a real whistle. I love that you can use it without putting your mouth on it. Just press a button and get the same effect!
It’s super functional and easy to use. I bought it to use as a coach, it’s WAY louder than I thought it would be. Would buy again!
