It's all about parts-per-million of scent. Think about it.... let's put "ability to smell" on two scales; one scale would be a human scale and the other is a deer's scale. Let's take two people as examples.
Human #1: has been working outside in hot weather sweating all day in cotton clothes.
Human #2: has just taken a shower with non-scent soap and put on clothes washed in non-scent soap and hung out to dry before donning.
Most all of you would agree that smelling human #1 would not be difficult to the human nose, right?
Human #2 would be very difficult for the human nose to smell.
That's all on a human nose smell "scale".
Why would this example not apply to a deer's ability to smell... just on a different scale.
It's all about parts-per-million of scent molecules. Can you overcome your smell whether it be gasoline, laundry detergent, bacon, etc... well, not entirely but a hunter can do A LOT to lessen his/her molecules of scent.
I don't think we as hunters can totally overcome a deer's nose but we can make it much more difficult for a deer's nose to pick up our scent.
I do what I can and I think I make a difference with my efforts HOWEVER, I still hunt the wind.
