SPOTLIGHT! SILENCER! and BALLS! (and get out of jail free card)Or just wait till rut and hope for the best. I've got a ton of shooter bucks on camera at night but haven't seen any of them during the day. I let a nice 7 pt. walk Sat. cause I wouldn't hang it on the wall. Sometimes it takes a lot of "but time" in the stand to kill a big one and sometimes it's just luck.
Maybe move closer to their bedding areas. But you have to be careful you do not push them away. But a lot of guys put them close to fields or where the deer are feeding, which is great but bucks won't be there until after dark. Hunt and get closer to where they are bedding and you might see them before dark.
might not be enough time left but try and move your cameras down trails leading to the feeding areas, to determine which path the buck is using, and if all the stars and moon align you can set up along that trail as close to the bedding area as you can without pushing them.
