The lower nitrogen content of nitrox makes it a safer choice over air in many situations, and it has the benefit of extending your bottom time. As long as you have the proper training to use nitrox, you can use it to dive more and more safely.
Nitrox is a good compliment to both the Deep Diver and Wreck Diver specialties.
