Pro Cure Bait Injector System - It's no secret that even top quality bait oils squirted onto a bait wash off too quickly. The secret is to inject the oils into the bait. Then oils slowly seep out of your bait, leaving a scent trail in the water that fish literally follow right up to your bait. Oil impregnated baits produce vicious strikes that produce many more positive hookups. Top quality construction. Float your worms with oil, not air!
