The Berkley Dredger has a weight in the lip to help the smaller size bass fishing crankbait get to the bottom quick and stay at depth longer. The hard plastic deep diver has a knocker. The hardware on this crankbait is solid. Solid split rings. Decent hooks. A durable paint job. This particular crankbait caught a bunch of bass and still looked pretty good. The lips are pretty durable. They get scuffed like any good crankbait that grinds bottom a lot. But I was more impressed that the baits didn’t scar up badly with teeth rash and such.
