The owner of Hoosier Trapper Supply made a DVD a few years back titled “Coyote Trapping”.
It is simple and to the point and packed full of information. I have it and would highly recommend it.
There’s a kid on YouTube that has a channel called Coon Creek Outdoors and he has some good videos.
Also, if you’re gonna spend the money, go ahead and spend the extra money and buy four-coiled traps or MB’s. You won’t regret it.
