Precision Diving represents the efforts of Duane Johnson to promote excellence and adventure in scuba dive training for the Chicago and Great Lakes area. Individuals seeking high quality scuba classes, I provide a very comprehensive and rigorous curriculum. Only such a program will ensure divers have the ability and knowledge to increase their comfort and confidence underwater. I've built my unique training programs based on my own personal experience in Nitrox, Trimix, tech, shipwreck, cave diving and DIR training.

We are serious fun!!!
