Wwoodrow88,

You have to be ready when the deer reaches the point were you will have a shot. I have seen many hunters wait untill the deer are right on top of them to standup or reach for thier bow. Just this movement however slight can alert the deer. If you hunt a heavily hunted parcel the deer are more alert and do often look up when they hear you. I suggest that you need to be twice or three times more alert than the deer or they will bust you every time. When you set your stand make sure that it's high enough but not so high that you are skylined, put padding on the platform, and make sure your clothing and bow are dead silent when you draw. Hope this helps. Good luck and hunt safe.
