These sand eels will bring large bass into the boat and are pretty much bluefish proof! We fish these rigs for the spring and fall bite. We attach a sand eel trailer down the middle on a 30 inch leader. The big Bass cannot resist this combo. These eel rigs are our favorite bass trolling rig. Give it a try....you wont be disappointed.
