Yea, after I had to have help taking that one off, an old trapper showed me that trick with a light cord. But I have a better one now. O don't go out setting connibears alone. My partner finally retired and we go together now. I lock the springs then hand them to him. He puts them in the location we want them in. I drive the stakes to hold them in place. Then he sets the trigger, releases the spring clips, and we are done there. He wears big heavy padded welding gloves. He snapped himself with a small 110 last fall, He has a healthy respect for those 330s.
Seen a 330 kill a German Shepard a few years ago. Instant kill, them big things have some power.
