That's it. I use it to compress the springs, then once they're latched, I move it to the actual trap part. It's nice having a locked trap set while I'm getting everything ready.
Al do you think a live trap like a HavaHart could work on an otter?
One fear with a live trap is with my luck a skunk would get in the trap.
Not sure what you do when a skunk is in a live trap.
