Made from real whole fresh bait, these pure uncut oils are the most powerful in the industry. Enhanced with powerful antioxidants to assure fresh, quality scent and potent fish-attracting flavor. Oils can be used to marinate baits in, or inject into baits, or squirt onto live bait or lures. When you're after catfish, sturgeon, halibut, fluke, flounder, and other bottom feeders. Heavy Liquids are fish oil emulsions that sink like a rock, then break up and crawl along the bottom, sending out a heavy scent trail right to your bait.
