Nitrox Requirements
Nitrox presents new hazards to divers, with the increase of oxygen being the main concern. The increase in oxygen results in shallower maximum depths, special equipment requirements, and additional dive planning.

To use Nitrox, you must complete a Nitrox specialty course. This course will teach you how to plan your dives, select appropriate equipment, and verify the oxygen percentage in your mixture. Most of this course involves classroom lessons, and dives may or may not be required for certification.

The most significant equipment requirement for Nitrox is a specially cleaned cylinder labeled for use with Nitrox. Another item that's nice to have, but not required, is a dive computer that's Nitrox compatible.
