Some clients shoot prematurely, before the PH has a chance to determine if the animal is worth taking. And sometimes before the animal can even be positively identified. Hence the PH's instruction, "Don't shoot until I tell you to."

Example 1: Client is on a lion bait. PH tells client to wait until he says to shoot. Lions come in to the bait. PH is glassing the lions. Client shoots a lion cub.

Example 2: Client is hunting leopard. 2 leopard are hitting the same bait. One is a big Tom and one in a junior male. PH and Client sit on the bait until after dark. PH says that he will turn on the spotlight when they hear the leopard feeding, but that the client should not shoot until the PH says to. PH hears a leopard and turns on the spotlight. Client immediately fires and kills a 70 pound male leopard.
