there are volumes to be written on this subject. If yo want to save the fur, use a small CENTERFIRE like a .17 rem or a .204 ruger. They don't exit and you don't sew. (Most of the time) Use the same camo that you would use for bowhunting ot turkey hunting, including a facemask.
Any call on the market will call them in, but I like an electronic because it gets the coyote's attention away from me. This allows me to get away with more movement. These things are not to be taken lightly as the coyote sees and hears like a turkey and can smell like a deer. good luck
Oh yea, dont forget to pay attention to the wind!
