I agree with the above. I would hold off on the calling. More likely to run him off then bring him in. Only use when you see him and he's not close enough or coming in your direction. Sounds like you have your own sanctuary. Dont let them detect you and dont overhunt the same spot. Just be patient. Remember you only get what you put into it. If you want the big one you're going to have to work for him. Good luck, I hope you get him.
