The 4" Sea Mine is a bait that can't be over looked when fishing. This popular urchin style bait has a unique presentation that causes tiny vibrations in the water that those bass can feel in their lateral lines. Our 4" Sea Mines have a 19mm ball in the middle and pairs well with most rigging options out their. Our favorite and most simple way to rig this is on a hover rig or a 3/0 Tokyo rig. These are made out of a very durable plastisol that offers a natural sink rate when fished weightless. Get yours today!
