Tying a uni knot stopper is easy and quick, once you get the steps down.
Here’s how you do it:
1) Run a length of mono parallel to the main line above the cork.
2) Form a loop, with the ends of the stopper mono facing opposite directions.
3) Loop one end of the stopper mono five or six times around both the main line and the stopper mono running parallel to the main line.
4) Pull the tag ends of the stopper mono tight to form a neat knot.
5) Clip the tag ends.
Now all you have to do is move the stopper up and down the line to set the depth for your bait.
