I actually like the relaxing locks. I have NEVER had a coyote get out of one once he is in it. Since Indiana has the 24 hour check law, it does not matter if the coyote is not dispatched by the cable. A lot of states have more relaxed check laws. Guys that run long lines cannot get to every set, every day. I could see where they want the coyote D.OA.. So they use the cam/ ratcheting locks, and kill springs that does not back off when the coyote quits pulling. The longer they are in there alive, the greater chance they have of breaking something, or chewing out. One advantage I have snaring fences, 90% of the coyotes I catch, jump over, or back through the fence, and are dead when I get to them. Setting in heavy brush, will do the same thing. They get tangled up tight, and its lights out. I cannot find any regulations against it here, but there is a simple entanglement device that can be used when snaring open trails. Its basically a rebar snare support, that is driven in the ground far enough to hold a coyote. They wrap up on it, and it does them in quickly.
