For over 20 years Pro-Cure has been recognized for supplying the finest quality fish oils in the industry. We all know how effective these fish oils have been. Yet many biologists tell us fish have a hard time recognizing and smelling oil based scents. The perfect scent would be a water soluble fish oil. Well, for the first time ever, that's exactly what Pro-Cure has done. Water Soluble fish oils that totally dissolve into the water column travel faster and further than regular fish oil, and are easily picked up by a fish's olfactory receptors (the ability to pick up smells and scent in the water). Plus they are UV enhanced and loaded with amino acids to trigger strikes. One sniff and you'll realize how much more intense and easy to smell these new water soluble fish oils are. They are perfect for injecting into baits, or squirting directly onto marabou jigs, glow bugs or chunks of sponge. They won't matt down the finest hair or feathers. Water soluble fish oils will wash off faster than regular oils, but don't worry. We packaged them in our new 4 oz. squeeze bottle, rather than our normal 2 ounce size.
