all that stuff is part of the "machine" that the hunting industry has created in order to get you to spend big money on just another set of camo clothing, scent free soap, or a spray bottle of water such as dead down wind. Much like many other BS products that are out there. Learn to effectively hunt the wind. That is how you overcome the nose of a deer or any other animal with such an acute sense of smell. I once owned scent lock when I was 18, and it never kept me from being winded when a deer was down wind. Traded it for a boat motor the next year to a friend. Will never use again.
