Iwouldn't worry about the buck being spooked . He had come in to investigate the new scent in his area and when he didn't see another deer there he just turned and walked away. The only thing that I would do ismove my stand to another tree 20 to 30 yards away just to be on the safe side and give thestand a couple of days break. Try to set up on himin another location 400-600 yds away not to disturb your area you seen him in.
