I used to train a couple of dogs for competitions where they had so many minutes to find x number of birds. The olfactory senses on these animals is mind boggling.
Anyone who works with dogs will not believe much of this scent elimination stuff. I have to believe deer are at least the equal of a dog in regards to scenting abilities. I hunt and trial beagles and have owned bunches of them for years. My beagles can find me by following my tracks (made with rubber boots), many hours after I have left the track. Not only that, but they can tell my rubber boots from a large number of other tracks made with rubber boots. I've tried to fool them and cannot. I've sprayed the bottoms of the boots with Scent Eliminator and cover scents. It doesn't slow them down a bit. Think about this. My dogs can tell which way a rabbit is moving by smelling the track. They can detect the difference between the track they're running and any new tracks that cross the original one. They can easily determine when a rabbit has "backtracked". I've seen them following the track of a rabbit without missing a turn, while running as fast as they can. And for those who think rubber boots leave no scent, they can follow my rubber boot tracks much easier than any animal track.
I don't own a carbon suit and don't plan on ever spending the money to get one. If I had one, I'd bet anything that my dogs could find me as easily while I was wearing it, as they can when I'm not. Having studied my dogs scenting abilities over the years, has convinced me that you are not going to fool an animal's nose with the scent elimination stuff they're pushing on us at this time.
