Like SS56 I'm not a big fan of the "boat whistle" types of calls either but they do work.They're just not loud enough. I don't want to coax a gobble I want to force one- "shock gobble". I'd pick up a reed style call like the Palmer and practice with it. Don't discount the use of your crow call in the pre-dawn hrs. either. A shrill-loud blast from your crow call on one of those "coulda heard a pin drop" mornings can really livin the woods up.It'salso a good way to change up that every day hum drum that seems to start up every day in April.
