I always make sets with coyote in mind because they are the dominant one here. These sets also catch most every fox that happens by. Because the trap pan is kept back of the hole or scent object about 10", many times fox step right over the trap to get up to the scent. This many times results in rear foot catches on fox, but a catch is a catch is a catch. On the other hand, if one sets trap pans too close to the hole or scent object with fox in mind, he will many times find just a set of coyote tracks just back of the trap pan where the coyote took a sniff and a peek and moved on without further investigation.
