I'm sure no one here that does different scent control measures thinks for a second that an elk can be down wind and we can go undetected to their nose. The place that I feel it helps is when I call that bull into 30 yards & he is not quite giving me a shot. He is looking for the bull, trying to get a scent location and if my scent control can buy me an extra half second ( or what ever time ) then I call that a good investment. I surely would not want to be in that situation with a smoke in my mouth & a tuna sandwich in my hand. ALL the hours of shooting practice, hours of scouting, money spent on bows & equipment and all the prep that goes into your season. I see no reason not to put effort into washing my clothes , wearing rubber knee high boots, & spraying a little scent control spray on my head net. I have seen the results & even if it gives me false confidence when that bull is right there pissing all over himself & raking the tree , it is well worth it to me. Mike
