Let me first state, predator calling for Javelina should only be used in a situational manner (I'll explain later). If used incorrectly or in the wrong situation, predator calls will prove worthless. In fact, it will scare the Javelina herd away 99.9 percent of the time. Despite predator calling limitations, it's without a doubt the most exciting way to hunt Javelina. Using a predator call exploits the Javelina's propensity to counter attack predators and come to aid wounded or distressed herd mates.
