I think Steves line makes a ton of sense. I dont ever look the animal in the face and try to focus on the feet/hooves whenever Im stalking. Not until Im ready to shoot do I like for the vitals.
That said, I love DIY projects. Ive been making my own scent spray and unscented soap bars. To be honest, Im not sure how important scent killers truly are. Ive had a fox come less than 10 yards from me when I forgot the scent eliminator spray.
Still, the scent spray works on my socks! totally kills the smell and it stays that way for a while.
16oz regular hydrogen peroxide
4oz baking soda
1/2 teaspoon colloidal silver
mix water, hydrogen peroxide and baking soda in a large jug that can breathe. The pressure is gonna build. Stir it everyday
After 4-5 days when foam subsides pour into a spray bottle and add colloidal silver.
Shake it when you use it, the baking soda will settle.
Scent eliminator is a questionable necessity (I like that term). Wind, position, silence and restraining your predatory aura will go way farther than a few sprays.
This scent killer works great for cat shit on the rug!
