If you've tried "Extended Wire" methods of four coiling traps and found that they fall apart when trapping coyotes or other aggressive animals, Try Beefer™ Spring Kits.  They give any trap extra holding power and speed.  They keep traps working through frozen ground, snow and ice.  Thousands of professional and part-time trappers wouldn't be without them.
