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 there. These are non TPE and have a natural sink just like your other favorite baits. They can also come in contact with most of your other baits without melting to them unlike the TPE versions. 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!
