OFFICIAL WHISTLE

but somebody else might. I wouldn't pay $35+ for a gadget plus batteries and a charger when I can use a cheaper and proven fox 40 for $4.50. Also, on more of a side bar, we are referee's. We BLOW a whistle just like football, volleyball, etc.. too much of a hassle to change something so important to the game - and too much room for error.

By the way, in women's NCAA, the Lead official blows the whistle before administering a throw-in on the baseline or on the sideline, free-throw line and down as long as the ball is staying in the frontcourt. This may be why you we hear the whistle more often.
