I know you're kidding about not knowing if that's a shooter.
Notice that the deer clearly sees the IR emitters and is less than impressed. Many deer will avoid an area with conventional IR cameras after they get "zapped" a time or two.
Unless that's a pigmy Key Deer with a 12" spread, he is definitely a shooter. Keep in mind that if you pass on him this year, he may not be there next year. All the while, you will be wondering about him .....
