The SSI Extended Range Nitrox Diving program, or XR Nitrox, provides divers with the training necessary to independently plan and conduct limited decompression (15 minutes or less) dives to a maximum depth of 130 feet, using decompression gas mixtures of up to 50% and technical diving systems and procedures in the equipment configuration used during the program with an equally- or more-qualified team. The XR Nitrox diving program is the entry-level program into decompression diving. This course is a fantastic initiation into back-mount twins, stage cylinder rigging, mounting, and use as well as technical diving systems, operations, and decompression procedures.
Why learn decompression?
learning to use proper planning and procedures for modern decompression diving can open a world of opportunities that no-stop divers or “Sport Divers” just don’t have access to. It can mean the ability to venture deeper with assorted mixed gasses but often it means being able to spend more time on the deeper dives you already do and love. The absolute most time a no-deco or “sport diver” will get at 100 – 130 feet is in the 10 – 15-minute time range. planning and properly executing a decompression profile will get you significantly more time.
As an example… Using a VPM planner, we plan a first dive of the day to 100 feet using 32%. On this dive, we can now do 20-minutes staying at 100 feet without deco. If we allow up to 15 minutes of deco on the same dive using 50% for our decompression mix we can now do a 45-minute dive at 100 feet! And that’s if you want to spend ALL of your time at the deepest point. For most purposes, Planned decompression will open up an incredible amount more time at depths up to 100 feet and those advantages continue as you go deeper. Being able to spend 3 times the amount of time a sport diver can in a single dive is quite a bit of fun. That’s why it’s so much of an advantage to learn to do decompression.
