Hey buddy, Thats a big question ,I think it depends on what time of year, what tyoe of game you have around. Rabbitt distress is always a good one. Birds, house cat, turkey, and mouse or rodent all work well. this time of year coyote vocals work well also.I would start out with howels and yips for15 or 20 min. and then go to distress if you don"t see anything.If you are near a dairy farm the cat in distress is a killer call. Cats and coyotes do not see eye to eye, if you know what I mean. What kind of caller do you have?
