RE: scent killer or cover scent.....
I use nothing but the wind. The only scents I use are doe in heat or buck scent. I only use these to stop the deer for a shot, not necessarily to attract them. I wash my clothes in plain water and dry them outside. I only wear these clothes for hunting nothing else. This includes boots, gloves and hats. No snowblowing or other activities will see these clothes. I do not believe that you can eliminate,kill, cover or mask human scent. Play the wind. Hunt smart. Don't waste your money. There is nothing quick and easy about outsmarting a deers nose. Play the wind and don't walk on their trails.
