🛡️ The By The Shore Training Advantage:

Unlike crowded dive shops that rush 10–12 students through pool cattle-calls, By The Shore SCUBA limits class sizes to low student-to-instructor ratios (typically 4:1). You receive individual coaching from PADI Master Instructor Kevin Alexander in a heated indoor Raleigh pool and calm Fantasy Lake spring quarry.

✓ Small Class Sizes • ✓ Heated Indoor Pool • ✓ Stress-Free Pace • ✓ Authentic Competence

Detailed Course Curriculum & What You Learn

Module 01

Module 1: The Physiology of Enriched Air

Understand why breathing higher fractions of oxygen (up to 40%) reduces nitrogen absorption, dramatically increasing allowable bottom times on repetitive and deep dives.

  • Nitrogen absorption kinetics vs. air
  • Oxygen exposure tracking & CNS clock management
  • Equivalent Air Depth (EAD) calculation
  • Maximum Operating Depth (MOD) limits
Module 02

Module 2: Gas Analysis & Cylinder Labeling Workshop

Gain hands-on experience using precision digital oxygen analyzers to test scuba cylinders, verify oxygen percentages, and complete cylinder fill log tags.

  • Digital oxygen analyzer calibration against ambient air
  • Gas verification within 1% accuracy
  • Cylinder labeling and fill station documentation
  • Dedicated nitrox cylinder valve and O-ring inspection
Module 03

Module 3: Dive Computer Configuration & Gas Switching

Learn how to program your personal dive computer for single or multiple nitrox blends, set maximum PO2 limits (1.4 bar / 1.6 bar contingency), and manage audible depth alarms.

  • Programming dive computer oxygen percentages
  • Managing PO2 partial pressure limits
  • Plan safe multi-day vacation dive profiles
  • Emergency air-sharing protocols with nitrox mixes

Provided For You

Heavy Life-Support Scuba Gear

Gas analysis instruments, calibration equipment, oxygen sensors, and training cylinders are provided during the hands-on practical session.

Student Provided

Personal Snorkel & Dive Kit

Your personal dive computer (to practice nitrox programming). No in-water gear is required if completed as a non-diving workshop.

Frequently Asked Questions

Does Nitrox make you dive deeper?

No! Nitrox does not increase depth limits; in fact, due to oxygen toxicity limits, each nitrox mix has a strict Maximum Operating Depth (MOD). Nitrox allows you to stay LONGER at recreational depths (e.g. 50–100 ft) with less nitrogen accumulation.

Do I have to do open water dives to get Nitrox certified?

No open water dives are strictly required by PADI standards. You complete online eLearning, followed by a hands-on gas analysis workshop with Master Instructor Kevin Alexander. Optional quarry checkout dives can be added.

Is Nitrox useful for Caribbean or liveaboard vacations?

Yes! Nitrox is virtually mandatory on liveaboards and multi-dive Caribbean charters (such as Cozumel or the Florida Keys) where you perform 3 to 5 dives per day.
