Yes and no. I have used Scent lok (correctly) and I think the product works. I just thinks it works for a limited period of time. However, I still think it's has some scent control value after the carbon is full. So at the very least it's not hurting your chances any. For me personally, I have the camo that I want and need so I am not going to buy more just to say I have Scent Lok. If I came across some at a good deal I would purchase it for the fact that it's a good garmet. I personally feel like it's impossible to beat a deer's nose and the limited amount of benefit (1% or whatevery # you want to use) is negligible because I believe it's not going to make the difference in whether a deer smells you or not. As the saying goes work smarter not harder. It also applies to hunting. There is no substitution for hard work and hours in the stand but you take a guy that works his butt off and spends as much time in the stand as a guy that spends an equal amount of time and has a better understanding of deer of better knack for patterning them etc. and he is going to out hunt the guy that works his butt off and flosses with activated carbon etc. etc. I don't knock anyone for using if you feel like it gives you and advantage.For me, I don't feel like it is going to or has in the past, influenced the success of my hunts. Therefore, I am not going to (here you go GMMAT[8D]) spend the money for something that I don't think will benefit me or give me more confidence. I will take that money and lease ground in the midwest instead. Yes I could afford to do both but I could also afford a new tractor or a new ranger boat but I wouldn't use either one of them enough to justify buying one. Give me two garments of identical price and I like the scent lok garmet better, then you bet I will buy it. I am just not going to spend more money or phase out my old camo for something I don't believe gives me the statistical advantage that say a week in Illinois would, or any measureable advantage at all for that matter. If you use scent lok then that's great! If you don't use scent lok then that's great too!
