I don't agree with much of the above advice... I have been hunting predators for close to 40 years and often with archery gear... while you probably can't completely fool the nose of a coyote, wolf, deer, bear or moose (wild animals survive using their senses)... you CAN reduce the amount of scent that you are distributing and you can narrow the scent cone downwind... this can only up your odds of success... I go to great lengths in scent control... even knowing that it may only help in 10% of the scenarios that I find myself in... to me field time is precious and I want to maximize my opportunities.
I wash my hunting clothes in a scent free detergent and then hang dry outside (when in the bush I hang dry draped over spruce, cedar or balsam boughs)... I store in large RubberMaid bins with a few cedar or balsam bough tips... I don't wear my hunting boots at gas stations, I don't sit around a campfire in my hunting gear etc... etc... I do my best to reduce foreign scents attached to the clothing and gear that I am using when actually in the bush hunting. I also take care with other gear, such as hats, packs, oils on my weapons etc...
This topic always raises a lot of lively discussion and I am not going to debate on this thread... but I can cite numerous events where I was successful and I am certain that my scent control efforts made the difference. I feel that many people disagree with scent control because they just don't want to be bothered and are convincing themselves ( and others) that it doesn't matter... they will say that wind thermals will swirl and spoil all of your scent control efforts (and they may)... they will tell you stories about Jim Bob who spilled gas from the outboard all over himself and then went out and shot a record buck... some will say, "I didn't shower for a week and the coyote came in straight downwind and never smelled a thing" etc... etc...
For myself, in my experience and observations, I am convinced that the efforts I make to control scent are worth it.
I don't really care what others do... but I won't be sharing a blind with someone who is wearing Aqua Velva and smoking a cigarette.
