When all else fails, and he's not comin in...
You can try to make him jealous.
You might get a gobble call. The best ones is called a pillbox or snuffbox call.
They produce the most realistic gobbles and don't cost anything to make.
They show you how to make one on theField and Streamwebsite.
Word to the wise, you could scare him off or he may come runnin especially, if you use it with a hen call as well.
Make him think another gobbler is movein in on his woman.
Also, BE CAREFUL!!!, People will hunt you when you use this call!!!
And I would make it a last resort.
Good Luck.....
