Working the whistle.

[blindzebra]

One long sharp blast.

This can be practiced by loosely holding the whistle with your lips and blow it with enough force to blow it out of your mouth...had a hearing impaired official with a weak whistle, he couldn't hear it, and this helped him a lot.

Other whistle tips:

Don't have it in your mouth when you toss the jump ball.

Find out what the local view is on whistles for bringing in subs...in my area it's a no-no.

Don't blow it on every throw-in.
