Gulp imitates the natural odor and flavor of live bait! Works good on a lead head. All the advantages of soft plastics and live bait wrapped up in one revolutionary new product. After nearly 20 years of extensive research using expert chemical engineers, fish behavior specialists, bio experts and top professional anglers, Berkley introduces its new line of Gulp! Saltwater Baits. Whether you're fishing expansive flats, a wreck or oil rig, the fact that saltwater fish love shrimp remains the same. Durable and long-lasting, they look, smell and feel like live shrimp. Molded using a 100% all-natural compound, these baits release 400 times more scent than standard scented plastic baits. Fish can detect scent from Gulp! baits from distances that even live bait can't match. And since they look and move like the real thing, fish simply can't resist them. The 100% biodegradable plastic-free construction means they are completely environmentally safe. They are highly durable to last through multiple fish. Per 6. GSSHR4-NP
