I've printed off the Arkie and Bandit dive curves listed all over the forum, laminated them and taped them to the inside of my clear plastic crankbait boxes so that I'll always have quick access to them. I started using the Precision Trolling book a long time ago, then transitioned to the iPhone app but never took much to it. I still keep the book under my driver's seat in the boat but just have to flip the lid open one one of my Stowaways to check for a quick reference.
