Patrick, I hunt the southern Jersey marshes myself. Set out some bufflehead and bluebills in short lines of about six each. Set them in groups to the left and right and leave a hole in the middle. Don't set them too far out because the divers tend to skirt the edge of the dekes. Throw some black ducks into the mix but keep them seperate from the divers. Try to set up on a point if you plan to shoot the divers, however keep the blackies out of the wind and place them in a wind shielded area. There's not much need for calling, they will come in if you're still. You can even wave a black flag to get the attention of the divers, I have had success with that, but if you see blacks put the flag away and don't move. I generally use about 30-40 decoys in the salt marsh. Only six or eight will be blackies. By late Novermber you will be shooting bufflehead, goldeneye,hooded merganser and brandt. If you find a grassed in back water where they are gathering, just hide the boat and wait. Don't put out the dekes. They will probably come back if everything looks okay. Push pole through the flooded ditches to try to jump some birds. This is much easier and quieter that walking the puddles. Good hunting to you.
