This Big Fin Roto chip bait holder has the large head (¾" wide) and two size 5/0 barbless hooks for strip and baitfish from 6" to 7" long. It works well with strip, herring or anchovies as bait. The large E Chip is built in. The strip or baitfish is placed in the head and the adjusting wire ring is clicked tighter until the bait is held in the teeth. The diagonal fin on the back is ¾" high in order to give the large bait the proper roll. The rear hook position is extended to place it at the tail of the large baitfish. See model A for smaller bait
