I had a bro shoot a scaup duck and catch it out of the air while walking down a levy earlier this season. Right in front of me.

When you put on the jerk cord put some black elastic on the other end of it about 20' will do, it's cheap at any fabric store. That way you can reel it in then let the elastic pull it back a little at a time. Or if you let the whole thing go, it will leave an awesome wake right thru your dekes.
