I am curious with the older bucks do you typically get more than one picture of them? They seem to notice the Cam. I never have luck with that unless i hang them pretty well hidden and they cant see it.
IMO mature deer are a whole different breed. Early in the year you have to have your camera soooo close to their bed in order to get any consistent pictures. I have never noticed a mature deer not showing up because they noticed a camera. They just don’t like to travel much. But also remember no two mature bucks are the same. They all move differently and some are patternable but I have found most are not.
