This lure is very productive for all pelagic species, especially dolphin and tuna. The head has a concave face and produces a great bubble trail to attract the fish. It is a color that mimics the colors found on a dolphin and we all know that all fish eat small dolphin. This lure can be run over a rigged bait, or rigged and run by itself without a bait. When used over a rigged bait, it makes it more attractive, easy to see, and prevents the bait from washing out. A must have on any serious fishing trip!
