Computer Nitrox Diver (SDI)
$250.00
Includes training plus required PADI/SDI student materials and certification fees.
The Computer Nitrox Diver course is designed for certified adult divers who want to safely use enriched air nitrox with a dive computer. You’ll learn how to analyze nitrox, set your computer correctly, and manage oxygen exposure so you can plan dives more conservatively and extend no-decompression limits. Training is conducted privately or in a private group, allowing time to build real understanding and confidence rather than rushing through procedures.
- Level: Specialty
- Agency: SDI
- Format: Private (1 student) or Private Group (2 students)
- Typical time commitment: Several hours of focused training, often completed in one day
- Training: Nitrox theory, oxygen exposure limits, gas analysis, computer setup, and dive planning
- Prerequisites: Open Water Diver certification or equivalent; minimum age 18
- Notes: Nitrox fills, dive site fees, or boat fees are not included and vary by location

Overview
The Computer Nitrox Diver course is built for certified adult divers who want to use enriched air nitrox confidently with a nitrox-programmable dive computer. You’ll learn how to analyze your gas, set your computer correctly, and plan dives within safe oxygen exposure limits so your dive time and decision-making stay conservative and clear.
Because this course is primarily academic and hands-on (no dives are required), it’s an efficient way to add an important capability to your diving without forcing unnecessary in-water requirements. In a private or semi-private format, you’ll get the time and attention to learn the “why” behind the numbers—not just the steps.
Outcome: earn your Computer Nitrox Diver certification and leave with a repeatable, safety-forward process you can apply before every nitrox dive.

What You’ll Learn
- What enriched air nitrox is and why divers use it (benefits and limitations)
- How oxygen exposure affects dive planning and why depth limits matter
- How to determine and apply a maximum operating depth (MOD) for your mix
- How to analyze a cylinder with an oxygen analyzer and verify the blend you will breathe
- How to label cylinders and record oxygen percentage, MOD, and key dive data
- How to set your dive computer for nitrox (FO2) so calculations are accurate
- How to plan conservative nitrox dives without entering decompression obligations
- Common nitrox mistakes (and how to prevent them) before and during your dive day
Why This Matters
- Helps you avoid preventable computer-setting and gas-identification errors
- Strengthens your pre-dive discipline: analyze, label, log, and verify every time
- Improves confidence by making limits and alarms understandable—not mysterious
- Supports safer decision-making through clear oxygen exposure awareness
- Gives you more flexibility in planning repetitive dives while staying conservative
Course Structure
- Knowledge development: nitrox fundamentals, oxygen exposure, depth limits, and practical planning concepts.
- Hands-on workshop: analyze at least two cylinders, practice proper labeling and logging, and build a reliable pre-dive workflow.
- Computer setup practice: program a nitrox-capable dive computer for common mixes (within recreational limits) and review what the screens and alerts mean.
- Review & certification: confirm understanding, complete knowledge checks, and finalize certification processing when course requirements are met.
Most students complete this course in a single focused session. Timing varies based on your comfort with dive planning and how much practice you want with analysis and computer setup.
Gear & Materials
Required personal gear:
- Mask, snorkel, fins
- BCD, regulator
- Dive computer (nitrox-programmable)
- Exposure protection appropriate to conditions (wetsuit or skins as needed)
Specialty items used during training: oxygen analyzer, nitrox cylinder(s), and an air cylinder for calibration (provided during the training session when required).
If you don’t have properly fitting gear, we’ll help you choose appropriate options. Rental availability varies by location.

FAQ
Do I have to do open-water dives for this course?
No dives are required for certification. The course focuses on knowledge and hands-on gas analysis and computer setup.
Do I need my own nitrox-capable dive computer?
You’ll need access to a nitrox-programmable dive computer to learn the setup process you’ll use on real dives. If you’re still choosing one, we can guide you during the consult.
Will you teach me how to analyze my tank every time?
Yes. You’ll practice a repeatable process: analyze, label, log, and verify—so it becomes your normal pre-dive routine.
Does nitrox make diving “safer” automatically?
Nitrox can offer planning flexibility, but it also introduces oxygen exposure limits and depth constraints. The course teaches you how to manage those limits conservatively.
What if I feel rusty with dive planning?
That’s common. Private instruction allows us to slow down, review the concepts, and make sure you understand what your computer is telling you.
Can this be completed in one day?
Often, yes. Timing depends on your learning pace and how much practice you want with analysis and computer configuration.
Where does the training take place?
Knowledge development can be arranged to fit your schedule. Any hands-on components are planned around practical access to cylinders/analyzer and local logistics.
What if conditions or logistics change?
Since dives aren’t required, the course is highly flexible. If any planned logistics shift, we adjust the session to keep training safe and effective.
Ready to Get Started?
Your phone consult is where we confirm prerequisites, discuss your current computer (or the one you’re considering), and map out a clean, conservative approach to nitrox that fits your diving plans.
If you’re ready to build a dependable pre-dive nitrox routine and understand your computer with clarity, schedule a quick call and we’ll take it from there.
