Are you using decoys? Or just blind calling (as we call it)? Are the birds feeding in this field? What is the setup?

Now calling geese isn't as simple as blowing on a call, you have to practice, listen and learn from actual geese. You have to know when to stop or go, tone vary and use different calls (contact, greeting, comeback, etc.) Most important don't be discouraged, b/c it takes time, practice and loads of patience.

I would suggest answering some of the above question, so we can better understand what maybe happening.

Good Luck!
