Cover scent as a saviour? Naw, but maybe they can help a little. I spritz just the slightest amount around the decoy, or, if an electronic caller is used with a remote where ever the speaker is. I position that so that I'm below and downwind of the perceived air cone/stream. An approaching coyote as it slides into that downwind position as they most often do, is locked on the decoy/speaker and smell, and trots into my set-up "kill zone". That is "if" everything goes as planned!
I want to sell the set-up to the oncoming coyote and convince it to relax, come over, grab a bite and sit a spell. Covering the smell of the decoy/speaker (if I were to use e-callers - I don't) and adding the idea that maybe that decoy bobbing around is really something scrumptious with some mouth watering squirrel/rabbit scent, or that there may be a lesser predator around such as a fox or coon, might add enough realism to hold the coyote for a shot. You know, much like how your appetite spikes when you walk into the house when you're cold and hungry and smell something good being prepared in the kitchen? Say the little lady has been baking cookies and the kids are already tearing into them, the smell spikes the appetite, the thought that you better grab one before the kids gobble them all, probably makes you walk into the kitchen, take in the scene, and snatch one right then. The perfect anology would be if the kids scampered out of the kitchen and then the wife walked in to see her cookie plate cleaned out and you standing there with a half eaten chocolate chip in your hand/mouth - and BOOM! She lays into you! Your greed and the added visual, hearing, and smell stimuli got the best of you!
If the coyote gets too far downwind and catches my scent, I doubt I could cover that with a gallon of cover scent. Remember the coyote smells it all and has the ability to break it down into the various parts. We smell cookies, he smells chocolate, flour, sugar, brown sugar, eggs, vanilla, salt, ect... My decoy is kept as scent free as I can make it, and stored in a clean white plastic bag with cedar limbs and oak leaves. My clothes are washed in cold water with unscented soaps and line dried. My hunting boots and clothes aren't worn when working or cutting wood, ect... I'm not a fanatic about scent control on the clothing, but I do the best I can and try not to expose them to human type odors.
In the thick cover of the heavy timber and brushy creek bottoms I hunt here in the Ozark's every second counts. A critter can blow in and out in a matter of a few short seconds and if that scent holds him for an extra 2-3 seconds, well maybe I get a shot. Maybe it's a confidence thing, thinking that I've taken every step I can to make the very best set-up. I don't rely on the cover scent and totally ignore wind direction, that'd be foolish. I do know this, I've had coyotes directly downwind of my decoy trot to within just a few yards of it. Surely if they smelled too much human odor they'd not approach it so closely. If I could ever resist pulling the trigger maybe I could see what would happen next... /ubbthreads/images/graemlins/grinning-smiley-006.gif
