I do both , here is what to expect so you can choose what you want to see happen . Non stop calling = coyote comes in fast and does not have to use eyes and nose to find origin of sound = rodeo .
call a little then quiet = coyote has to search for origin of sound = coyote comes in slower and more cautious, sometimes useing ears, eyes, and nose . easier to kill in my oppinion .But harder to fool .
both have their place , it depends on what YOU want to happen , remember your the caller you should control the coyote not the coyote control you .
Non stop calling in heavy brush or in areas where you have dips and othere factors available to the coyote can become what i refer to as a rodeo . You lose control of the set . in open areas this is not a bad set up as you will be able to see the coyote coming in get it in your sights and stop it for the shot .
In tight cover or in areas where the lay of the land can be to the coyotes advantage you want to use call and silence technique . This is my oppinion and means nothing , Its just what i have done for a few years and works for me .
