I don't know what a deer smells and what it doesn't or why sometimes they seem to react one way and next time the opposite.
I've hunted in hot, wet, sweaty, stinking, tennis shoes and had deer walk all over my fresh tracks and pay no attention what so ever and had them cross my back trail when I was wearing knee high, rubber boots, blow and run off in the other direction.
I've used a lot of cover scents over the yrs..but never found a way of knowing if they worked or not..so just decided I could find more meaningful ways to waste my money.
