Absolutely NOT. It is overrated and I myself have shot more deer without it than with it. For one, it is way OVERPRICED. Remember, majority of guys on TV get it for FREE and it is normally a sponsor. Save your money and invest it in your equipment such as a good bow/broadheads/etc. As long as you wash them with scent free soap OR even baking soda and keep them in a plastic tub; get dressed in the field and still hunt the wind you do not need scent lock ..IF you have it you STILL need to hunt the wind. Dont get caught up EVERY thing that is brought to the market place.
