if your hunting with a bow deffinatly,this is my second year doing bow but 15 with a gun and I noticed a major differance.I personally keep my gear out side I Never wear my gear inside my vehicle they go into a bag of leaves for the ride and then I spray down with scent spray I use deer dander on my boots and use the scent soaps all through the season Never use any cologne durring season also I don't know if it helps but I keep a pocket full of apple jolly ranchers lets face it most of your scent comes from yourmouth that cannot be covered so Breath is a mojor deal IMO anyway that or I'll eat mapple or vanilla flavored candy and this year I have seen more deer than ever in my life and I am hunting state land with a lot of pressure, where as last year I saw 4 and didnt use much scent control other than keeping my gear out side, Now for rifle hunting where you have 50yrd shots or better play the wind it dosnt matter as much
