I use scent control to some extent. When I first started hunting, i bought into it all. I had every scent gimmick out there and used about every cover scent known to man. Over the years, I realized that I didnt need as much as I was using, but it was still importan. These days I wash my cloths in a non scented detergent, and i spray scent killer over my cloths and boots before i hit the woods when i get out of my truck. For me its just a 20 dollar bottle of insurance. I have been in stand, and watched a deer come up behind me, and put its nose to the ground and smell the EXACT line i used to walk into the stand a half hour earlier, and then bolt. Not only with deer, this also has happened with fox and coyote. That said, wind is king. Wind is always on my mind, and should be for hunting. Even the best scent control is pointless when you dont care about the wind. I have had deer bust me when i am upwind of them and not used scent control, because i've experimented with different levels of scent control on different hunts just to see reactions of deer. For the times i've dont it, the number of deer i see DRASTICALLY get reduced when i dont use any kind of scent control. I hunt along a lot of ridges where the wind tends to swirl a bit, and i've seen deer between 70 and 100 yards away take off because they knew something wasnt quite right as they sniffed the air. No one is gonna completely remove their scent, and its pointless to completely try. "Forget the wind, just hunt" but scentblocker brand is bogus IMO. Remembering wind direction and movement is the single most important thing any hunter can do (especially bowhunters). If i smell like smoke and pizza and work, the deer arent gonna come running in, especially if theyre downwind. Wind is important, period. Some scent control using eliminating sprays helps the wind you cant help (swirls, wind direction change ect.), as well as spraying down your boots helps with scent control as well i believe.
