Nitrox Certification

What is Nitrox? Scuba divers used compressed air in scuba tanks for diving. Air contains 21% Oxygen and 79% Nitrogen. Increased partial pressures of Nitrogen is what limits our dive times and also causes Nitrogen Narcosis. How do we reduce the amount of Nitrogen in the air that we breathe? Simply add Oxygen to our breathing gas! Nitrox Certification will allow the recreational scuba diver to use between 22% and 40% Oxygen in their breathing gas. This increased Oxygen will increase dive times, and reduce surface intervals. The Nitrox Certification class will teach you how to choose the Best Mix for your dive, how to compute Partial Pressures of gases in your mix, and teach you how to safely analyze and dive your gas. 

Why Choose Trilogy Dive Center for your Nitrox Certification? When you walk into our shop and see our hyperbaric chamber you will realize that we are not your average dive shop. We understand Nitrox and other advanced gases as it is used for treatment gas in hyperbaric medicine. If you want to learn Nitrox, Trilogy Dive Center is your choice. We are the only dive shop in the area that teaches and practices hyperbaric medicine, teaches and practices emergency medicine, and supports commercial diving operations. 

Dive Computer Class

Dive Computer are pretty straight forward but you must know how to interpret what you see on the display. Most users learn the basics underwater through trial and error and by asking questions on the surface. Unfortunately, computers do not operate on the surface as they do during a dive. Bring your computer or use one of ours and lets go for a chamber ride! In the hyperbaric chamber the pressure will change just like on a dive, except you can TALK to your instructor. This allows you to view your computer and ask questions about the display and settings while actually under pressure.

The class starts with general computer information and how they work. You will get a chamber briefing to understand what to expect inside the chamber as the dive gets underway. You will dive to a depth of 60ft and work with your computer, asking questions and learning how it operates. This is also good practice for equalizing ears. Few scuba divers will ever see or a chamber or get an opportunity for a chamber dive. Bring your computer and your log book and see what the chamber is all about while learning to use a computer!
