Fitted with the new Pro-Troll EChip™ that gives off a tiny electrical pulse with every tail kick of the flasher, the ProChip flasher adds deadly ionic attraction to your hootchie or squid. The diagonal fin causes superior rotation. Bottom is embossed in silver, while the top is fitted with glow tape. The diagonal agitator causes an erratic action that big predators just can’t ignore. Convenient and easy to use, it never wears out. And a single Echip can be used on several different lures. Per each. Sizes: 4", 8", 11".
