I sometimes work in a place that has several adjacent courts going at the same time. After doing a little research on this topic, I think I'm going to start using a Pearl when I do those games so that my partner and the players recognize my whistle from the ones on the surrounding courts.

I saw one a guy had at Coast to Coast in Vegas last summer. It is a little bigger and had a different sound. Those who like it like it for the different sound.

Thanks to all of you for your replies !

I send you a link to see this whistle, to Molten Japan.

One of my friend sent me one's, and i like it for the different and more powerful sound it produces.

Thats it...that is the one I saw.
