[Raymond]

On common violations like travelling, palming, or double dribble my communication consists of a loud whistle w/open hand, clearly pointing the direction of the subsequent play and clearly pointing to the throw-in spot.

However with fouls I immediately verbally communicate to my parter(s) the location of the throw-in or the number of free throws. If free throws are involved I make sure of some sort of communication (verbal or non-verbal) with my partner(s) indicating we are aware of the correct shooter before I proceed to the table.

If a partner calls a T I try to verbally communicate to my partner the team shooting, basket, throw-in location before he reports to the table.

I communicate to my partner(s) when bonus goes into effect. If my partner calls a non-shooting foul during the bonus I immediately find and point to the shooter and raise the appropriate fingers to indicate shots to be taken.

I'm a big believer in effective communication among the crew.
