GENERAL COMMENT:
IMO, I think we all have to do what gives us confidence in preparing for hunting...but after it's all said and done if we don't hunt the wind we're busted and we don't even see the deer downwind that detect us and turn away.
All the different approaches to washing ourselves, washing our clothes, etc, etc, really don't amount to much when you consider that most people still put on the same pair of smelly boots they've worn for years, and wear the same old smelly leather belt that's saturated with scent, and wear the same hat that hasn't been washed after every use, and wear the same wrist watch which if it has a leather band is also saturated with our scent...we're carrying firearms that stink of our scent from handling them, plus the smell of oils and finishes...and the final over-arching issue is our breath...we expel an average of 100 gallons of hot stinky human breath every hour...a constant stream of our scent floating down wind.
And while treestands provide a benefit by minimizing the effects of our movements of close deer since they put us up above the normal field of vision, they really don't do much to eliminate scent...downwind deer simply get wind of us further away.
I quit doing anything extreme, anything out of the ordinary for scent control 10-15 years ago and just concentrate on hunting the wind...and frankly, if anything my results have improved some. IMO, the bottom line is that we cannot eliminate or hide our human scent and make ourselves become invisible to wildlife...any breeze will inform downwind deer of our presence.
