I posted this some time ago, the idea being that if you were a good hunter, you didn't need anything to try and cover your scent, but apparently it wasn't interpreted that way.
I seriously doubt if any of the scents sold will cover your scent so that wild game animals won't smell you through your perfume.
You have to stay down wind from the game, but many hunters don't realize what a light air movement it takes to carry your scent. If you can feel the breeze on your face it is easy to know where your scent is going. It is when you can't feel any air movement that your scent can be carried to the game.
Old time hunters used various ways to determine which way the air was moving, when it was too light to feel by normal means. There has been no end of cartoons about someone holding up their finger to see which way the wind is blowing. But it works! One must first put your finger in your mouth to slightly dampen it, then hold it up for a few seconds and the side that is into the wind will dry first.
If conditions are right, another good method is to use dusty material from the forest floor. Take a pinch of it and slowly rub it together with the fingers of an out stretched hand. The dust will angle with the wind as it falls.
I Northern Ontario, the hills guarantee that the winds shift constantly. Particularly bad when there are light winds. All you can really do is position yourself in the spot you think least likely to be upwind. I've seen the wind completely switch direction in minutes, only to switch back. A hunter cannot depend on wind direction alone to ensure his scent stays away from game. Minimize your scent, use a cover scent if you're comfortable with that, higher is better WRT to tree stands, but even they are not a guarantee. Distractions for the deer in the form of decoys, or artificial scents can work, but not always, at least for big bucks. They don't get big by being dumb. If they don't like your decoy, you'll never see them, if the scent you are using has a chemical smell to them, same thing.
For me, it comes down to the basics, eliminate as much scent as possible, hunt from down wind, hunt from height where you can, ELIMINATE movement. Leave the candy bars, cigarettes, the coffee, and anything else that will cause scent or cause you to move, back at camp. I even avoid drinking much in the morning so I don't need to piss. (scent & movement)
Western hunters tend to see animals at much longer ranges, and conditions are much different, they can afford more movement than an eastern hunter can. Most of my game has been shot inside 50 yards, much of it inside 50 feet, and a few inside ten feet. For game that close, you best be a statue.
I have fooled deer in bow hunting by ducking down and putting the crossbow up in front of me like antlers, but the wind was near perfect for that and I was in olive coveralls and face mask. I've done that three times now, twice with does, and once with a nice 265lb buck I got with the crossbow at 21yards.
