scent lock is like all the camo on the market. It helps but is not the only solution. Common sense has to prevail. I bow hunt hundreds of hours every year killing 2 deer a year and don't have the answer but I have not spent any money on these expensive clothes. It's real simple, keep your odor to a minimum and you will get busted less. The cheapest route is to get 20-25 feet in the air and you won't get busted. Think about your worst discharge: breath and yea I garggles with baking soda. Save your money, shower well and wash your clothes with non-scented detergent and don't drink or have sex the night before.
