You can buy coyote and rabbit urine, look in Trapper Predator caller magazine. I mix the coyote/rabbit urine 50/50 with water and strain it good, if you don't strain it good it could plug up the atomizer.
A good plastic spray bottle like what window cleaner comes in works fine. When you see a coyote heading downwind you spray it high in the air in a mist form, the mist well carry a long way right to the coyotes nose.
NO it won't hide the human smell but it well confuse the coyote long enough to take a shot. I've also seen the coyotes come in because they smell another coyote beating it to the rabbit.
I've been doing this for years as have a few others, so I know it works. In the last couple years more and more people are finding out about it.
Trust me, You'll never fool a coyotes nose with scent free anything, It simply don't work on a coyote. The best you can do is try to fool or trick the coyote at best, I like to use the word confuse.
