Bowhunters Fatal Obsession (BFO)

I've tried a lot of scents, attractants covers over the years and found them all hit or miss. if used at precisely the right time and way I've had bucks come right to it as if on a string and lick it off the trees other times it's ignored or think it may have actualy kept game away. one product I liked to use as a cover scent when up in a tree was racoon urine, it seemed to put them at ease if they caught motion or sound from up there.
