I have personally never hunted coyotes on my own but I am figuring on getting out and doing some this year. The question I have is how long (when using an electric call) should you let it run? A couple of buddies I have gone along with in the past both have different ideas on calling. One says a couple minutes is all you want to call and the other says to let it run for up to 20 minutes. So, from you that may be more familiar I would appreciate your info and input on the subject. Thank you!
