No amount of "scent tactics" will ever eliminate your scent.
I remember reading two separate articles about the same study a grad student did on hunting pressure one a large lease in the Carolinas. It was a very exhaustive study that included over a 100 stand sites with tight controls. I'll see if I can dig it up, but the results clearly showed that deer quickly respond to human presence at site sights no matter how hard you try to avoid detection. He found that older bucks would avoid a stand after a single occurrence of detecting a hunter, and a significant idle period with no human activity before they returned.
Of course you will find no shortage of those who defend their routines by saying deer get used to them driving all over their leases and parking their ATV's next to their stand sites. And during the rut when a buck is so sex crazed that it might chase a doe through the middle of their camp, they luck out and take a trophy. However, the old saying "They don't get old being stupid" is as true today as it was at any time in the past.
"More than 100 stands are spread throughout the property. For each one, McCoy designated a visual danger zone of 100-150 yards around it, meaning bucks that moved into the danger zone put themselves at risk of being harvested. At any one time hunters occupied 20 to 30 different stands. Each hunter was dropped off at their stand before dawn, stayed until lunch, and then returned to their stand in the afternoon.
By the end of the study, McCoy found that each adult (2½ years of age and older) buck’s location averaged 55 yards farther from stands than at the beginning of the study period, demonstrating that adult bucks adjusted their movements in response to hunting pressure. Yearling bucks did not move farther away from stands as the season progressed. McCoy noted that yearlings were protected from hunter harvest, so they didn’t need to move farther from stands as the season progressed.
If a buck stayed out of the danger zone of a stand, McCoy surmised the deer was responding to hunting pressure. He was surprised to learn how quickly bucks would react to the presence of hunters.
“After a hunter had sat in a stand just one time, bucks would stay out of the danger zone of that stand for the next three full days, meaning they wouldn’t return, on average, until the fourth day,” explained McCoy. “This finding held regardless of whether the hunter had shot at a deer. Just occupying the stand made bucks stay clear of it for several days.”
Another interesting finding was that the age of each buck did not affect the likelihood of it staying clear of danger zones. In other words, younger deer weren’t more likely to move through danger zones than older bucks, dispelling the long-held assumption that mature bucks are more intelligent than younger bucks (see sidebar).
Not surprisingly, use of bait sites during daylight hours decreased as the hunting season progressed. At the beginning of the season, half of all visits to bait sites occurred during shooting hours. By the end of the season, only one in four visits were made during daylight hours."http://www.grandviewoutdoors.com/big-game-hunting/how-much-hunting-pressure-is-too-much-for-deer/
