Call me compulsive or OCD, but with my system, I have deer downwind of me (treestand), without being busted, on a regular basis, and have for years. None of these were big bucks, but lots of does and medium - smaller bucks. Here is my formula, basically the same as you will get from Steve Bartylla :
rubber boots, only used for hunting and stored and treated as has been noted above. Shower with unscented soap daily, clothing washed in same, aired out outside, and stored in plastic bags, same with pack, bow haul line, rattle bag, etc etc. Scent lok clothing on the outside, finally ASAT 3D leafy suit over top of everything. I spray down my bow, arrows and quiver lightly with some type of anti-scent spray. No: scented deodorant, shampoo, hair gel, etc. Brush my teenth & tongue with baking soda before going out. I keep everything in totes or scentproof bags and no matter the weather, strip to my whitey tightys while standing at the back of my truck, and redress from my gear boxes & bags. LW climber treestand is stored outside starting in about August.
My conclusion is that my scent is reduced to the point where the deer conclude whatever human is responsbile is very far away.
Since I went to this system about 10 years ago, including the ASAT 3D suit, I have increased my deer sightings by roughly 50%. My kill rate has also gone up.
Some folks, including my family, think this system is waaay crazy, but hey - it works !
Got two does so far this fall with my new Fedora HP recurve - shoots like a dream. Keep passing up small bucks - maybe I will get lucky this weekend.
Good hunting everyone
