This is a technology that just is not necessary, at least not for me. I started out hunting without an understanding of scent and quite frankly I stunk. Then I read an article in D&DH-- way back. It suggested baking soda. I tried it. It worked. I stopped getting busted.
Here it is 20 years later. I go out to my stands and have deer walking by, and walking underneath me all the time. Yes, once in a while I get busted, but it's usually when I'm up moving around. Scent-wise I'm pretty invisible. Meanwhile, I see these expensive carbon suits and spray products and I got to scratch my head. For me, they're trying to fix something that ain't broke.
I also think this thing about scent is somewhat overblown. Yes, I will admit that I used to be over-the-top fastidious about things, but last year I was one of the ones that tested the pee-off-the-stand idea hatched on this forum. Not only did I see 4 nice shooter bucks, but in one instance I think the sound of the pee falling on leaves actually brought in a doe and two fawns.
