The 9-inch Ernie lure is proven in both freshwater and saltwater applications. The Ernie dives 6 to 15 feet on a cast and up to 30 feet when trolled. The integrally molded dive lip is designed to hold up to continuous contact with rocky bottoms and the durable plastic ribbed construction holds up to the largest predatory fish. The high frequency tight wiggle mimics an escaping baitfish and allows it to be trolled at high speeds. It is surprisingly easy to crank on deep retrievals.
