Fox 40 Classic Mini CMG Whistle Outdoor Safety Sports Referee Football - Black

This is a good whistle that is loud, easy to use, and comfortable to carry. It works well while wearing gloves or when using it with bare hands. I often wear a whistle around my neck, but there are frequently instances where the finger whistle is the right tool for the job. I have used both this model and the Pearl, and I feel that they are solid choices. The rubber cover over the finger area gives a good grip, while still being comfortable. The whistle has a slightly higher-pitched sound than the classic, sonic, and Acme Thunderer.
