May I ask the OP where it's written that scent spray must be used or that blinds have to be brushed in to kill a deer? Weishun prefers to hunt with handguns almost exclusively and that's his choice. I'm not defending him or his tactics but I think many people have bought into the notion that the only way to kill a nice buck is to use certain products or to do it like some of these so called pros do it. Sir , would you even know there was a product like scent killers if you hadn't seen some "pro" hyping it on tv and if that pro killed a big buck using this stuff then we all gotta use it. I'm a hunter of 44 years and have killed many nice bucks while sitting on a stump being quiet and watching the woods. We do not need all this stuff to kill a deer. It's marketing pure and simple. Flame on.
