What You’ll Learn
By taking this combined specialty course, you’ll gain the knowledge, skills, and confidence to safely explore deeper depths while diving with Nitrox. Here’s an overview of what you’ll learn in each of the specialties:
Deep Diving Specialty
- Planning Deep Dives: How to plan and execute dives to depths of up to 40 meters (130 feet), considering dive tables, gas management, and decompression procedures.
- Handling Depth-Specific Challenges: Understand the physiological effects of deep diving, including nitrogen narcosis, oxygen toxicity, and dealing with cold-water dives.
- Advanced Buoyancy Control: Master buoyancy techniques for deep water, including proper weight distribution and the use of specialized equipment.
- Dealing with Emergencies: Learn how to respond to emergency situations at depth, including buddy assistance, out-of-air scenarios, and emergency ascents.
Nitrox Specialty
- Understanding Nitrox Blends: Learn about the different Nitrox mixes (e.g., 32%, 36%) and how they impact your dive planning, safety, and no-decompression limits.
- Oxygen Toxicity and Safety: Gain awareness of oxygen toxicity risks and how to avoid them by monitoring depth, time, and gas mix.
- Dive Planning with Nitrox: Master how to plan dives using Nitrox to maximize bottom time and minimize nitrogen absorption, including how to use dive computers and dive tables specific to Nitrox. As Diving with Nitrox also reduces the surface interval needed between repetitive dives.
- Cylinder Handling and Safety: Learn how to identify and properly handle Nitrox cylinders to ensure safe diving practices.
Course Structure
The SSI Nitrox & Deep Diving Specialty Combination course is designed to give you both theoretical knowledge and practical experience. Here’s how the course is structured:

Benefits of the Nitrox & Deep Diving Specialty Combination
By combining the Deep Diving Specialty with the Nitrox Specialty, you’re setting yourself up for a more enjoyable and safe diving experience. Here’s how these two specialties work together to enhance your diving:
- Extended Dive Time: With Nitrox, you can dive longer without increasing your risk of decompression sickness. This is especially important for deeper dives where dive times are typically shorter with air.
- Improved Safety: Both specialties focus heavily on safety, with an emphasis on managing oxygen toxicity, preventing decompression sickness, and understanding your limits while diving deep.
- Recreational Diving Flexibility: With the combination of these two specialties, you can enjoy a wider range of exciting dive sites, including deeper water sites with wreck diving, caves, vertical dive sites with amazing walls or coral-encrusted walls and deeper coral reefs, all while diving longer and safer than ever before.

The Nitrox Specialty can also be combined with the Deep Diving Specialty on a single dive, which means you will get to see how the percentage of oxygen in enriched air mixtures directly effects how long you are able to spend at the maximum depth compared to on previous deep dives such as on your Advanced diver training course compared to these training dives. It may have been a while ago so you may need to look it up in your divers log book for details from previous training dives. This is why at our dive school we generally head to the deeper dive sites in the mornings so the diving times for the Nitrox course usually involve an early start.
