I don't know if this link will work; but I know the guy who wrote this article on trapping coyotes in his career he has probably filled several dump truck loads full of problem coyotes. The trap he is setting in the pictures are sterling mj 600's and they do fit inside a plastic sandwich bag when set. Those traps are powerful leg holds. Hope that helps.
