I definitely get busted fewer times and have more deer come around me since I started doing all of the sent control stuff. The key with sent control is to not skip steps. Make sure you shower in sent eliminating soap, use sent free deodorant, field spray, keep your cloths is a sent free container, wash them in sent eliminating detergent,and wait to get dressed until you are at your hunting ground. I have a buddy who bought a sent lok suit thinking that was all he needed. He kept getting busted and wondered why. turns out he never took sent free showers, he just left his sent lok clothes in his living room and never washed them. I told him no wonder it isnt working for you. Your hair smells like the shampoo you washed your hair with and you clothes smell like the food you cooked the night before. Hell, I could smell him from 20 yards away. Imagine how potent he smelled to a deer! ..............I do believe sent elimination can make a difference but in the end, getting down wind is the most important thing. The only way to fool a mature deer is to get down wind. Sent elimination is never 100% so don't ever kid yourself that you don't have to consider wind direction. Do both and your odds of success will only increase, IMO
