Sounds like your doing about what everyone else does. Your deer tracks that you're seeing must be made in the night if you aren't seeing the deer make them. Try moving your stand in the direction the fresh tracks are going in the mornings. You might catch them closer to their bedding site after daylight. If they are coming back to that spot after dark then you have already gone home, so by moving closer to where they bed you may catch them coming and going in the light. Shortly before dark is when you will see them and at first light. Try being in your stand and quiet for 30 minutes or more before daylight and after dark to see whats going on. Coming out of your stand 30 seconds too soon can make all the difference, so stay put and keep alert until a few minutes after legal shooting ends. Not to try and shoot after legal time but to see if they are coming in too late and from where? If you can move in that direction a few hundred yards and just catch them a few minutes sooner, then do it.
I have used one of the night owl, night vision spotting scopes and it works well for spotting deer just before light and after dark to see whats up. They cost about $160. at Wal Mart. Just don't use it for hunting, only for scouting, and only when not carrying a weapon, so you don't get in trouble. Unless your state allows it. Otherwise try a trail camera or two and see what time they are out there.
