You will be better served by assigning one person the job of shooter and the other the job of caller and backup. You will also do well by staying within whisper distance of one another so that you can converse locations of approaching game. If you hunt the open field terrain then point your gun downrange to begin with and you will avoid needing anyone to watch your backside. Setting up in places with the wind in your face tends to do a lot of educating of coyotes, IMO. I primarily hunt open fields and will always set up with the wind blowing straight in front of me when hunting this terrain. This flies in the face of what most people will tell you, but like they say different strokes for different folks, and I take far more than my share hunting my methods.
