Our Eel Umbrella Rigs feature 7 durable 6 inch eels that are fully rigged and ready to troll. We also include 5 blank replacement eels as replacements. These eels will bring large bass into the boat and are virtually bluefish proof! We fish these rigs for the spring and fall bite. The big Bass cannot resist this combo. This eel rig is our favorite bass trolling rig. Give it a try....you wont be disappointed.
