I used to play into all the scent stuff but I honestly think it is just all a big marketing success. I used to put on sprays, make a mud hole and work my boots in some cover scent and all the good stuff, but no more. All I do is I was my cloths in some non UV soap with no scents added, I think it is called whitetail institutes or something. Then I started to hunt above 20 feet and in the last three years I do not think I have been winded at all to my memory in my high stand. When I use to hunt on a 12 foot ladder I was winded some. But I use no scents at all going into the woods. I think all the scent stuff on TV is just a marketing reptelling a guy, "wear are stuff and brag it up and we will pay for your next high fenced hunting shoot". One thing I can add though is I think it depends on the guy and the area. I know guys at work that sweat like pigs by the time they are out of the locker room and by lunch they could make a skunk blush. Me, I do not sweat much at all, I think. LOL. But the individual may need more then others. Also the area, in my area I can see six or so houses from my stand. The human scent is all around where I hunt from all the people living in the country. I think it makes it harder for deer to pick you out if they are around it 24-7. Now if you where to go deep into a wooded area like up north or south of me where the deer are far away from anything and a person would be totally alien to the area, then maybe it is different, don't know. But I do know that since I started using non UV soap and went above 20 feet I started seeing alot more deer and had no scent sprays on.
