I use total scent control for whtetails and I believe it works well but it didn't work on brown bears. I went through the full routine of washing gear and myself in scent control soap, bagged the gear up in scent eliminated airtight river bag, wore the full suit including rubber boots and sprayed everything down before heading out. While on stand I watched a large boar skirting the edge of the swamp toward my stand. When he hit my 6 hour old trail where I walked in to my stand, he freaked out and almost tripped over himself to get out of there. I'm not so sold on the stuff any more. Of course, a deer doesn't have near the nose of a bear...
