RE: what call have you?
If they arent gobbling on their own, I prefer a Lomahn (sp?) crow call for a locater. I mostly hunt public land, and find soft clucks and purrs on a slate work pretty well. Its fun to get them all spun up with yelps and cutting, but my limited experience is that they come in better to the soft calls and just hang up at a distance waiting for the hen to come to them when I call too much or sound too excited...
