Primos Hunting Calls. Primos Fightin Horns. Always hunt into the wind while rattling. With their keen sense of smell, even a buck in pursuit of a doe in heat won't be foolish enough to be rattled up after he smells you. MOve to the edge of a core area very quietly and "set-up" next to some brush or a large tree to break up your outline. Wait 10-15 minutes to let things settle down before beginning. Grunt before, during, and after you rattle. The high-tech polymer of the Fightin' Horns delivers the same consistency and structure as real as antlers. The 14 contact points reproduce buck-fighting sounds from light sparring to extra loud fights. The extended handle design gives hunters the room to rattle without injuring their hands.
