When used with 360* Flasher or Dodger the 100lb unbreakable 49 strand coated cable cuts through he water with less drag and interference allowing your lures and bait to move with an action that the fish cannot resist. The speed and roll can be altered by using different length tuning bumpers. For a tighter, faster roll, try a shorter bumper cable. For a larger, slower roll, try a longer cable bumper. 20″ & 24″ are most common.
