Deer cocaine has worked very well for me. I've had one spot going now for about 2 years and it's about 6 or 7 feet around and maybe 3 feet deep. No lie. I put my camera on it all the time and it fills up quickly. Maybe my deer just need minerals more than your deer do. I don't get many daylight pics though. Most all of them at night. I wish I had a scanner and could show you some pics. There's a few with deer standind in the hole with their heads down and you cant even see their head. You might as well try it though.
