Every deer reacts different, and this one seems to be a regular hit/loss due to looking to soon. Your deer will be within 100 yds or so from the first bed it makes, usually. If it has to jump a log, or creek look for a drop or two on the other side. One of my customer that is a butcher, has told me of how many deer he finds with bhs still in them that has been calcified over them. Good luck!
