I wish I could put simple things like this together, but unfortunately I don't.
After reading this, and trying it yesterday, I think back on the times in the past that I've gone hunting for a few days and camped while hunting. Coming in to camp, warm up by the fire, taking a ho bath, and wearing the same camo for 3 days. I've killed deer on those excursions. Can't say if I have or have not been "blown at" during those trips. My memory isn't that good. I can say that this year when my clothes have been washed in scent free soap, dried in a scent free dryer, hung out to air out overnight, put directly into a plastic bag, and I've only put them on after a good de-scenting shower, using scent free deo, spraying down in scent killer before and after getting dressed, I've been blown at on several hunts.
Maybe it boils down to this, maybe it doesn't, BUT I figure there is no way to eliminate human scent. It can be knocked back, but not eliminated. Maybe concentrating on eliminating all scent, leaves nothing but human scent for the deer to smell. Maybe pure human scent, regardless of it's concentration is enough to spook deer. I guess that might be the purpose for cover scent. Not to mask human scent but to dilute it. I've never tried a cover scent that I could say really worked. Maybe smoke is just that.
