Simply the best & easiest way to control the depth of your leader with this innovated metal grommet. While everyone around me is struggling to find a solution to control their fishing depth, too high, too low or getting caught in weeds, with Stan's Slip Bobbers just adjust the slip knot and the bait dangles and stays just above the weeds. People are amazed how fast and how many fish I catch and it's not luck, it's the bobber, period. All my fishing buddies now use Stan's Slip Bobbers.
