Ok, the coyote winded you. You can fool a coyotes nose by diluting the parts per million of your scent with an attractant or bait as if it is legal. Coyotes can smell you for 250 yards down wind.
There are products that really work for diluting human scent, been using it for 10 years, and this product will give you a totally different experience when coyotes, deer, elk, bear do not pick up your scent. Contact:
byogeroge@aol.com, the product is dirt cheap for a whole season's worth.
Wear one set of shoes from home to the spot to where you are going to start hunting, then change shoes. When you pump gas for your truck, you are standing in gasoline. Your boots get saturated with gas and if a coyote crosses your track, he will smell it 10 feet away.
If you are a Smart hunter, hunt by the moon phases (major and Minor feeding times) in conjunction with weather fronts. Avoid hunting 100% of the time when the barometric pressure is rising, or a time when a high pressure system is parked over the top of you. Hunt, hunt, hunt on the leading edge of low pressure fronts, low pressure fronts, and immediately after a storm. This knowledge of hunting by the moon phase is the key to successful hunting.
Use camo on your face, hands, and gun.
Every piece of equipment you carry has your and your truck's scent on it.
Know your down wind side and set up where you can see down wind.
In heavily hunted areas, you can not make any mistakes, and I make longer stands, 30 minutes. I do not use standard vocalizations in hard hit areas. E callers are used by everyone, coyotes know what most of the sounds are, they are men. So, how do you change sounds to use something that they have not heard?
Attractants are very, very helpful in areas where they get called, and I can not stress this enough. You are mainly hunting the yearlings in these areas. I use two cans of sardines in oil in a dark cotton sock, and use two socks hunt as HIGH on a tree limb as I can reach. This smell has many more parts per million than your smell, especially if you use a product that diminishes your scent. However, you should spray your e caller and decoy with the scent eliminator also.
Learn to shoot coyotes on the run, trot, and walk. Waiting for them to stop, and often trying to stop them is fruitless. Lead them just like you would a dove flying with a shotgun, follow through. Always shoot them on the way in because it is much harder to hit one once he has stuck his nose to your caller.
I carry a hand pruner and prune myself a hole in bush to break up my outline, works fantastic and this technique only takes 5 minutes max to break up your outline.
In hard hit areas, you may put out some fox pelts on bushes as coyotes love to eat foxes and red fox pelts are even better. I put out some coyote pelts and it scared the heck out of coyotes, they are very leary. Give them a decoy of something that they like to eat, spray that decoy with scent eliminator or you will get busted, carry those pelts in plastic bag.
You should practice shooting off your NON dominant shoulder because 40% of your shots will come in from the wrong direction. With a tad bit of practice, you will see just how easy this is, just close your eye to aim.
I made a post two weeks ago that you should read on coyote hunting.
Good luck!
