The Deep-Diving Crankbait
My friends and I fish these baits down to 18 feet or more on Lake Fork. When a swimming lure runs that deep, all its flaws are amplified. These tweaks will keep it working right.

Detail the Hooks
Replace your lure's standard hooks with size 4 or 6 trebles to increase hooking power. Scrape all paint off the hook hanger eyelets, which will allow freer movement during the retrieve.
