These HI-VIS planer board release clips are assembled with 200lb mono, high quality crimps with Scotty 1182 mini release clips and a 2 1/2 inch foam oval HI-VIS float. These make setting lines in low light conditions much easier and improves visibility to ensure lines are evenly spaced and running properly. They also can be seen by other boats which is helpful when running Big Planer Boards.
