You will probably have someone tell you that you CAN"T fool a deer's nose and just hunt the wind. You should always hunt the wind of course.
Someone will likely also say that a tracking dog can trail you directly to your tree. If a dog can do that, then a deer with even better olfactory senses will smell you even quicker. They are right. A dog will come find you fairly easily.
HOWEVER..... The smoke appears to do something I don't fully understand to deer. They simply do not react like they would without it. I have yet to have a deer blow/snort at me when using smoke. Even when they circle down wind, they obviously catch a scent, but they just don't freak out. Sometimes they stay right where they are still feeding and other times they just walk away. THIS IS WITH THEM BEING DOWN WIND!
I have video posted on Facebook of a buck standing ON my walk-in trail WITH a bad swirling wind. He fed in the area for about a half hour before moving on up the hill. At one point, he even caught me moving while videoing him. He circled down wind to try to catch my scent. Even when the buck was down wind with his nose in the air, he couldn't figure it out.
FYI; I was in a tree, but only 8 feet off the ground.
Smoke works! From a fire or a bee smoker. Give it a go and see for yourself. I smoke everything including my boots. I also use unscented soap and deodorant mostly for allergies, but it plays double duty for hunting. I put unscented deodorant on my feet to keep them from sweating as well.
Good Luck!
