The Roto-Chip Bait Holder with an EChip has an easy slide locking device and requires no toothpicks, rubber bands, or wires * Embedded EChip bait technology duplicates the electrical nerve discharge of live bait, which triggers strikes by nearby predators * A diagonal fin gives the trolled bait the perfect rolling "wounded fish" action; the patented spacer tube holds the hook at the tail of the bait, which drastically improves the catch * Size #5A is for baitfish or strip up to 5 inches long and size #5B (Big Fin model) for baitfish or strip up to 7 inches long * Available in 11 colors and 2 sizes, it comes fully rigged with tandem 5/0 barbless hooks, 72 inch 40 lb. leader and 75 lb. test bead swivel
